blower motor resistor keeps burning out

Like hard hat said, the blower motor may be the problem (and will burn out the resistor again). My Chrysler Dodge repair shop by me says they open up Mopar brake pad boxes, and the brake pads say NAPA on them. So the resistor gets hotter at the lower speeds, and burns up faster. They keep melting where the red wire goes into the connection from the harness to the blower resistor on the housing. With that said, if the blower motor doesn't work at all it's also common to find a defective blower motor relay. This scenario is the same for pin 5 with the Med 1 position. Dakota Fan Huuuuum ! And then it works, but only for a year and then it burns up again and you say what the F#*@!!! 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). REPLACE THE BLOWER MOTOR RESISTOR AND RESISTOR MODULE CONNECTOR. Does anyone know the current draw specs for these motors? 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. Even if you use 100% OEM parts it still fails: The reason is………….For your 2001 to 2011 vehicle MOPAR didn’t make your replacement part. If that weatherstrip is hanging or fell off completely, then you have found the leak. Not only that but my abs, service engine soon, and trac off light are all on. 2. 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 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. I am going to wire in a fuse before the connector that keeps burning up. 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. Is that possible? Molten, damaged wiring and connectors. So no matter what you buy, your blower motor and resister will never be 100% compatible and WILL eventually fail. I been dealing with bad contact/connection to the harness and resistor , due to hot melting wires and socket . 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? A common symptom of a faulty blower motor resistor is a blower motor that is stuck on one setting. Next time water poured from the motor housing (worked 1 mo ). BUT I am having this same issue. Midsize Utility Vehicles - Blower Fuse 35 located in the Underhood Fuse Block. 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 replacing the connector and couple wires. It all stems from a/c drain design flaw. 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. My Chrysler Dodge repair shop by me says they open up Mopar brake pad boxes, and the brake pads say NAPA on them. Hopefully I have not confused you with all this. My wire harness melted. 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). long that is suppose to be attached to the steel lip just below the windshield. I'm thinking my blower motor is drawing too many amps and burning out the resistor. Edward Wong. 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). Hi folks. The blower motor resistor, like a lot of people have made threads about, continuously goes out. 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. It may be the blower motor itself has bad bushings or some such thing. and rotate the switch. It's possible for the electrical failure of the blower motor resistor to take out one or both of these fuses as it melts. Check that and the plug up to the blower and resistor for any melted wires. If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed. Note that the resistor is in the duct where the blower discharge is blowing on it all the time when running. Hi should not affect it as it is a short circuit through the resistor anyway. If the motor draws more current than the engineer who spec’s the resistors thought it did, this effect would be worse, and the resistors would burn out quicker. 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 Blower Motor Bad Not Resistor - ChevroletForum.com It happens again. 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. It has since conked out 3 different times. I am amazed that they allow such a large tolerance. Mostly on the trucks. It seems the blower it's from a junk yard . Check the motor draw when it is on high. Replaced my blower motor because it was noisy.....that fixed the noise problem; however since that time my blower motor resistor keeps blowing. Have not actually seen too many connector problems on the older Malibu's. I had this problem reoccurring! 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). That's where I would have to start at and make sure the blower has a good ground. After years of replacing the blown resister module 3 to 4 a year, I finally bit the bullet and bought a … Good luck. Good thing it isn't very expensive! So I got it exchanged and popped the new one in earlier this week. Hi jayeff, Definite design flaw. If you leave the blower motor switched continually on you may not notice this. Replace the blower motor resistor and module connector using the following procedure: Remove the blower fuse. Any suggestions on what may be the cause? 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. 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 Lower the hush panel or close-out … 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. Good point AnnMarie. If not then it may be a faulty blower switch. Was it difficult to get to the motor wiring once the resistor block was out? Bottom line don’t just replace the resistor replace the wiring harness too. Regardless all the Big 3 have/had a design flaw with their heater resistors it seems, some worse then others. The blower motor resistor was burnt out. Or the cowl panel is not sealed well against the windshield. A common cause for these failures is that water is getting into those components. heater blower, resistor keeps burning up? 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. Sorry, not the perfect fix but it is the truth, I’ve spent 2 years figuring this out. High blower motor bypasses the resistor pack for a straight shot to the battery. 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. I there anything that causes this on my car?
