It could also be an internal blower switch fault and that there is a short circuit connection between either the low and Med 1 setting or between the Med 1 and Med 2 setting. The wires will burn out before the fuse will. The blower motor resistor is the component directly responsible for controlling the blower motor fan speed. With that said, if the blower motor doesn't work at all it's also common to find a defective blower motor relay. The blower motor resistor was burnt out. When your Dakota or Durango left the factory, it had a Mopar motor and voltage resister that were compatible with each other. Oh sure it will say MOPAR on the box and say factory original OEM part, BUT ITâS NOT!!!!! Many Dodge forums tell of this problem. If you look into the female end of the plug you will see black in one of the holes where it blew out. They are turning the wiring into fuse wires. The Blower motor resistor in my plymouth breeze keeps burning up. Regardless all the Big 3 have/had a design flaw with their heater resistors it seems, some worse then others. Only use high speed fan setting for heat and AC. The second-generation Dakota began development in 1991, though they were not introduced until 1996 for the 1997 model year. I have had it replaced three time in the last 2 years. What could be the reason it keeps going bad? Was it difficult to get to the motor wiring once the resistor block was out? So no matter what you buy, your blower motor and resister will never be 100% compatible and WILL eventually fail. Note that the resistor is in the duct where the blower discharge is blowing on it all the time when running. I got in my truck this morning and had some frost on the windshield so I turned the defrost on, blower motor â¦ Although this isnât as common, the chances of this happening increase if you have a melted electrical connector. Midsize Utility Vehicles - Blower Fuse 35 located in the Underhood Fuse Block. Then they buy a aftermarket blower motor and again it keeps burning up. Unfortunately, the wire harness has to short several resistors before the mechanic starts to see that something is wrong. © 2021 iFixit — Licensed under Creative Commons — Privacy — My wire harness melted. Go to a salvage yard, find a low mileage Durango or Dakota and pull the motor and resister and then you will be good to go. Hopefully I have not confused you with all this. After years of replacing the blown resister module 3 to 4 a year, I finally bit the bullet and bought a â¦ I there anything that causes this on my car? http://dodgeforum.com/forum/1st-gen-dura... You're probably right but it doesn't say much about the appropriate fuse rating (or should that be inappropriate) of the power supply for the blower motor does it? So replacing both the blower motor and resistor at the same time fixed the problem. Replace the blower motor resistor and module connector using the following procedure: Remove the blower fuse. The double orange has one of the wires going to the blower motor and the other orange wire going to the heater resistor assembly. It's possible for the electrical failure of the blower motor resistor to take out one or both of these fuses as it melts. Parts used - Scitoo Blower Motor - Going on the figures below inserting a 20A inline fuse should be enough to prevent the wiring etc from becoming the "fuse" before the 40A fuse operates. Check the motor draw when it is on high. Still dealing with condensation discharge , as it keeps into the cabin , under the carpet . It is always the second pin on the harness that melts (tan wire). Have you had any time to pull the blower motor and lube it up and make sure it works with out any drag? As a service advisor working at a GM dealership for 9 years, I have seen this problem more times than I can count. It seems the blower it's from a junk yard . The FSM will tell you what it should be. Here is a the blower circuit for a 2002 Dodge Dakota. Edward Wong. and rotate the switch. Then thereâs nothing to resist and damper down voltage and it never gets hot. Excessive current flow, maybe a short to ground between resistor pack and blower motor itself. @dakotafan. It died again this morning. Hopefully it is the same for your particular year model. I am going to wire in a fuse before the connector that keeps burning up. Blower switch on non AC '69 keeps burning out. Related Discussions. I kept replacing them and they kept burning out but while they worked 3 and 4 came back then I would lose 4 and eventually 3 (within a month of new install). If the coils are burning up, they are seeing too much resistance. 1. Noboys makes their own parts anymore, mostly China crap. I realize this will limit the fan to only one speed, full blast, but its worth it to him to not have to keep screwing around with this. ... For the medium speed maybe the yellow is the output on the switch which then goes through the resistor assembly and then out to the blower motor. The blower capacitor is weak causing the motor to overheat (a good tech would usually replace both the motor and the capacitor after a motor failure). The usual cause of repeat failure is the blower motor draws too much current upon starting, the connector is burnt or melted or the replacement part is inferior quality. High blower motor bypasses the resistor pack for a straight shot to the battery. I'm replacing the connector and couple wires. That is why the resistor keeps burning out. Have not actually seen too many connector problems on the older Malibu's. Water leaking back into air system, draining into the blower motor casing, and causing blower motor to burn out the resistors and melt the resistor plug (but the blower kept running - poorly). Dennis Smith, Only mine to 05 Monte Carlo with a 3.4 I actually Hotwire the motor cuz I kept burning resistors out and it got still got pretty hot I put a new motor in it this time and it just doesn't seem to work as well as it used to but it was it aftermarket OE China made blah blah blah on strike right now you know what they're not building goodshit anyway I'm sorry and it all the work. HVAC Blower Motor Resistor - Compatible with Ford, Lincoln & Mercury Vehicles - Expedition, Escape, F150, F250, F350 Super Duty, Mustang, Mark LT, Mariner Replaces 3F2Z-18591-AA, YH-1715 4.6 out â¦ If you've read the comments in the answer below, since you have to replace the harness etc, perhaps you should consider connecting an inline fuse on the power supply feed to the blower circuit as well so as to protect the harness etc in the event of the blower motor going low resistance (shorting out between motor windings) in the future and burning out everything before the designated fuse can operate. Molten, damaged wiring and connectors. Bypassing or adding a relay to keep blower motor resistor connectors from burning out. Huuuuum ! Think I need to solder each wire. If you leave the blower motor switched continually on you may not notice this. Hi jayeff, Definite design flaw. heavyduty April 15, 2018, 5:36pm #6. Mine quit and moving the connector caused it to make better contact and it would work for a while. REPLACE THE BLOWER MOTOR RESISTOR AND RESISTOR MODULE CONNECTOR. The reason isâ¦â¦â¦â¦.For your 2001 to 2011 vehicle MOPAR didnât make your replacement part. That's where I would have to start at and make sure the blower has a good ground. Thanks for the interest, I wondered why also. I got this truck from a previous owner if not more . A common symptom of a faulty blower motor resistor is a blower motor that is stuck on one setting. The blower motor draws too much and causes the resistor to fail again. Good thing it isn't very expensive! Sep 25, 2017 | â¦ It almost seems like manufacturers were just happy to let the resistors burn up and kept their fingers crossed no body got burnt to death to sue their buts off. Then thereâs nothing to resist and damper down voltage and it never gets hot. Sorry, not the perfect fix but it is the truth, Iâve spent 2 years figuring this out. My number 5 setting quit working so I got the new resistor and it fixed the problem. There should never be a reading between the wires with the switch in any position. If the blower motor looks like it is rusty, or the resistor keeps burning up, then it is most likely water intrusion. As the blower motor runs, if a bearing is worn, it will seize up after getting hit, then this causes extra resistance and this will cause the resistor to burn out. From the passenger side fender, you can lift that panel from under the hood and look for a black weatherstrip about 18 in. I've had it replaced 3 times in 3 years, and today it â¦ My Chrysler Dodge repair shop by me says they open up Mopar brake pad boxes, and the brake pads say NAPA on them. It starts out slow and you figure there is something wrong with resistor, resistor connector (which melted) or the blower motor's old, or they-don't-make-these-blower-motors-like-they-used to. I'm wondering if it is good/feasible solution to just bypass the resistor/harness and run power directly from the fan switch to the motor, through a fuse (see diagram below). It happens again. Next time water poured from the motor housing (worked 1 mo ). Damaged wiring on the right side. Thanks for the link. The blower motor is probably worn out and drawing too much current causing the resistors to blow. Jump to Latest Follow ... has the blower motor and resistor easily accessed. It has since conked out 3 different times. If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed. You can even use cheap eBay parts etc. Blower Fan Speeds Not Working On My 2002 Chevy Impala, Chevrolet Malibu Overheating Even After Engine Replaced, Location of Blower Motor Resistor On 2001 Chevy Silverado, Location of Shift Control Solenoid in the Transmission, A/C Vents Blow Cold on Passenger Side But Warm Drivers, Engine Noises | Knocking and Ticking | Common Causes, Engine Dies and Then Starts Right Back Up, Dodge Avenger 2.4L Crank Position Sensor Location. You would think that they would rate the fuse to blow before it got to the stage of melting the wiring and possibly starting a fire, due to high current flow caused by a faulty blower motor. Replaced my blower motor because it was noisy.....that fixed the noise problem; however since that time my blower motor resistor keeps blowing. Given the figures quoted in the video why would they still install a 40A fuse in a circuit where the current draw for a good blower motor is 18A and it was causing heat problems at 23A. 11/03/2019 by Why hasn't NHTSA recalled here? If you are using aftermarket resistors try one from the dealer, inspect the harness connector for burning or melting of the connectors or housing and do a current draw test on the blower motor. And then it works, but only for a year and then it burns up again and you say what the F#*@!!! It is located under the glove box, it takes about 15 minutes to fix and costs about 20 bucks. I did soldier each wire from the resistor plug . I was about fit to be tied before I figured it out!! Only use high speed fan setting for heat and AC. My motor works but keeps melting the connector to the fuse. I'm thinking my blower motor is drawing too many amps and burning out the resistor. Itâs made buy a number of after market companys, mostly NAPA. Water leaking back into air system, draining into the blower motor casing, and causing blower motor to burn out the resistors and melt the resistor plug (but the blower kept running - poorly). Resistors do not burn out first. The Dodge Dakota (called the Ram Dakota for its final two years of production) is a mid-size pickup truck from Chryslerâs Ram division (formerly called the Dodge Truck division). Check that and the plug up to the blower and resistor for any melted wires. So I got it exchanged and popped the new one in earlier this week. The 40A fuse is to be the circuit fuse, Items in this circuit should be fused separately and should not add up to more then 40A circuit fuse. Does anyone see any issues/downsides to this workaround? If so I suspect that there is an earth fault on one of the wires connected to either pin 4 or 5 of the resistor. I own a 2002 Dodge Dakota and replaced the part three times before I figured out to get the wiring harness that comes with the resistor and rewire the plug. I finally replaced the blower motor and was fine for about a year. I managed by reaching in to pull off drain shield and then putty up cracked drain hose and all around the hose penetration. Retro the resistor to get better connection and problem solved. This scenario is the same for pin 5 with the Med 1 position. I would like to test it to see if it is out of spec before I replace it. Before I could tell when it blew, because it would only work on high. After 10-15 years the motor wears out , begins to draws more amps burns up the resister. Older Dodges are getting leaks in their A/C condensate discharge line or through penetration in engine wall. Figure 3. These have been recalled in Canada. I had this problem reoccurring! Trent, one of the biggest reasons for blower motor resistors to have shorten life is actually because of faulty blower motor drawing too many amps, some times melting wires/plugs, heating up resistors shortening their life. Checked other things first (since the blower motor was fairly new (fuses, relays, etc. Go to Edmonds.com with samequestion. heater blower, resistor keeps burning up? Is that possible? 06/14/2017 by terrywoodward74. When I replaced the resistor connector and wires (melted) I took the blower off the truck . Chevy it don't matter you know but I wish I understood the pain solution so I can figure that out cuz I am burning up in on the resistors which means it's getting too hot hi guys you did you doing a great job thanks a lot for a guy that you're working on 40 cars for 40 years, 09/16/2019 by That leaves you with no slow speeds and only the high speed. After a little while of A/C running , I check the wires and not hot . I've replaced the blower motor a total of three times, and the resistor a total of 5 times. This time, it all went out without warning and wouldn't even work in high!! Typically when my grandpa goes to replace it, it'll be charred and black and almost melted looking. BUT I am having this same issue. Look here for the "how to" with pictures. If the motor draws more current than the engineer who specâs the resistors thought it did, this effect would be worse, and the resistors would burn out quicker. Lower the hush panel or close-out â¦ also when you go to replace the resistor check the connector for signs of melting or burning you may end up having to replace that conector I changed the resitor for my blower motor in my HD about a month ago. Thousands of people have the same problem with their dodge. In my experience, the blower resistor shorts out due to an open in the pigtail harness. My hose was cracked. Hi..as I said the damn heater blower and resistor keep burning out on my intrigue. I finally found the simple solution and ultimately the actual cause to the issue of the blower resistor burning out and over-heating the plug wiring - The blower motor itself is the culprit! Replaced the resister ONCE AGAIN, and it works!! The motor is undersized. ), all seemed ok. Thanks for the input ! 2 people found this helpful. Blower Motor Bad Not Resistor - ChevroletForum.com When it burns up, will only work in high. Susie Whitacre. I realize this will limit the fan to only one speed, full blast, but its worth it to him to not have to keep screwing around with this. Noboys makes their own parts anymore, mostly China crap. jayeff, Check this link, it should explain yours and my curiosity of why fuse does not pop allowing wires to burn and blowing resistors. Like hard hat said, the blower motor may be the problem (and will burn out the resistor again). If not then it may be a faulty blower switch. Then again if your resistor appears burned or melted you may need to replace the plug with the wires (the wiring harness) and the resistor and probably the blower motor. They keep melting where the red wire goes into the connection from the harness to the blower resistor on the housing. There is a post I did some time back on the blower motor showing how to remove it and clean it. Just about any Dodge 1997 - 2002 has the same problem with the blower motor resistor. Replace everything or soldered wires to resistor to no avail. Even if you use 100% OEM parts it still fails: The reason isâ¦â¦â¦â¦.For your 2001 to 2011 vehicle MOPAR didnât make your replacement part. I replace it 3 times will work for a day or two in all fan speeds. Have replaced my blower resistor 3 times already in the past 2 weeks. I had to keep replacing the blower motor resister. Itâs made buy a number of after market companys, mostly NAPA. long that is suppose to be attached to the steel lip just below the windshield. Hi should not affect it as it is a short circuit through the resistor anyway. Noticed moisture on blower cage. Not only that but my abs, service engine soon, and trac off light are all on. 2004 Dakota with 4.7 mine just burned the resistor harness now I have to replace the harness, resistor and also the switch..i took the switch apart and the circuit board is burned out the fuse itself is good so the circuit board failed, 01/16/2019 by However I am suggesting that if for example you had an wiring earth fault on pin 4 and the switch was on Med 2 then not only would you have the normal current flowing through the resistor connected between pins 1 & 3 BUT you would also have more current because of the circuit path available thru pin 4 (which shouldn't be there). I put lots of WD-40 aot both ends and that makes spin much easier . It will work fine for a few days, maybe a week....then will only work on high setting....take out the resistor and it's blown. The one thing that caused mine to go bad was leaving the fan on when I shut the truck off, next time I started it, it blew the resistor. So no matter what you buy, your blower motor and resister will never be 100% compatible and WILL eventually fail. Bottom line donât just replace the resistor replace the wiring harness too. Does anyone know the current draw specs for these motors? This is because this is the resistor which carries all the current when the switch is in positions low thru med 2. cheap replacement from Autozone / Advanced etc. If the blower motor looks like it is rusty, or the resistor keeps burning up, then it is most likely water intrusion. Ok , think I figured it out . So the resistor gets hotter at the lower speeds, and burns up faster. This is a Video of one of the reason why we have to change this Piece so many times. My 1998 Chevy Malibu blower motor keeps going bad. The warranty covered the initial replacement but otherwise I am getting nowhere. 6 weeks ago I replaced my blower motor and blower motor resistor. I suspect that there will be no reading between pins 1 & 3. The solution was to buy a new wire harness kit, get yet another new blower motor resistor and replace the front blower assembly. Like I said, there are multiple videos and forums discussing this A/C condensate leak back into the vehicle and how to repair that. I'm wondering if it is good/feasible solution to just bypass the resistor/harness and run power directly from the fan switch to the motor, through a fuse -- like this: https://ibb.co/iBC7qV. Dakota Fan It will only operate on a full s/c. A usual place for water to enter into this area is a loose, or missing weatherstrip under the upper cowl panel. The cowl panel is the long plastic panel under the wiper blades/arms. I hope this helped you out, if so let me know by pressing the helpful button. I'm thinking a defective blower motor that isn't cooling the resistor as it should. You can even use cheap eBay parts etc. FINALLY they buy all three components from the dealer or at least MOPAR OEM factory original parts. A half watt resistor would burn out to prevent further damage while the 1 watt or bigger might allow too much current to flow through another component. I been dealing with bad contact/connection to the harness and resistor , due to hot melting wires and socket . I am amazed that they allow such a large tolerance. If that weatherstrip is hanging or fell off completely, then you have found the leak. 09/10/2019 by My Chrysler Dodge repair shop by me says they open up Mopar brake pad boxes, and the brake pads say NAPA on them. Need to glue that strip back into place to fix the water leak problem. Just the way it is today. With the plug disconnected from the resistor measure back toward the switch between the wires for pin 3 & 4 (light blue and light green/yellow) and 4 & 5 (light green/yellow and tan). So what is causing the resistor to burn out? Or the cowl panel is not sealed well against the windshield. It may be the blower motor itself has bad bushings or some such thing. It starts out slow and you figure there is something wrong with resistor, resistor connector (which melted) or the blower motor's old, or they-don't-make-these-blower-motors-like-they-used to. Then a couple days later itâs melted again. 05/30/2019 by To check the blower motor for bearing failure, pull it out of the heater box, leave the wiring hooked up, run the system as normal and keep an eye on it. Does anyone see any issues/downsides to this workaround? Getting tired of replacing it!! Matt Bennett. Replaced blower motor, resistors, and plugs multiple times. A lot of mechanics don't bother to troubleshoot the resistor failure, they just replace the component and move on. Accessibility. Figure 4. Does the blower motor run with the switch in the OFF position? Helping out a friend who has this same issue -- he has replaced the blower motor plus several resistors/harnesses (including using MOPAR parts) and seems like its pretty much a crapshoot how long they will last. Fix leak. It is a part that should have been recalled by Dodge the first year it came out. If there is no strip at all, then there was not a seal, and the cowl panel to windshield will need to be sealed with silicone or other sealer. Terms — Helping out a friend who has this same issue -- he has replaced the blower motor plus several resistors/harnesses including MOPAR parts and seems like its pretty much a crapshoot how long they will last. I have also had the blower motor resistor replaced once. Thank you for input totally appreciated it, 04/01/2020 by With a DMM (Digital Multimeter - Ohmmeter function) remove the blower resistor and measure the resistance readings on the blower resistor module between pin 2 and pin 1 (should read 0 Ohms) then between pin 1 and pin 3 then 3 & 4 then 4 & 5 and see what they are reading to find out which one has failed. Green eyed baby boy. Just the way it is today. It all stems from a/c drain design flaw. Hi folks. Mostly on the trucks. I try to run it in high so hopefully it last longer .
