I have a 2003 Dodge Durango 4WD 8 Cylinders N 4.7L SFI. The other day my A/C went out. I tried to switch out the fuses for the A/C unit that did not work. I found a bunch of information that it might be the Blower Motor resistor. Most of the posts say that they have some air flow in the high fan speeds. I have nothing coming out on heat or A/C. I am thinking of just changin out the whole blower motor and the resistor. The problem I am having is I cannot find anything online on how to take out the blower motor, just the resistor. If someone could help me out it would be cool.

Thanks

 

The reason for such a high traffic count on resistors is the high failure rate. One theory is that the motor puts out too much voltage and that is what causes the resistor fails. I removed my motor a couple of years ago and it is not that difficult. There should be three bolts and a electrical connector. If I remember correctly after the screws are removed the motor turns a slight bit, kind of like r/r a home sink garbage disposal. Being a 2003 I would recommend changing the motor and resistor at the same time. When changing the resistor check the electrical connectors, look for burn marks, melted plastic, etc..if in any doubt replace the wiring harness, you can get them at dealer for about $75 plus installing the wiring or in my case I got the harness of a donor at the junkyard and only cost me $25 including the resistor for testing/troubleshooting.

Good Luck!!

 

Well I took out the reistor and it was fused to the connector that the resistor connects to. Anyone know what that is connected to.

 

Your resistor must have overheated and melted itself to the wiring harness adaptor. Cheapest fix is to replace the wiring harness adaptor head. You can problaby find them at the junkyard on the cheap. Heard it is not cheap from dealer and you have to replace the whole harness.

More or less, it is problaby your resistor totally blown which will not give you any power to the motor at all. I would get this fixed first before spending alot of time to remove the blower motor.

Also, check to make sure your wiring harness is in good shape overall. We hear some cases, the harness gets a little wet/damp due to condensation buildup and ruin the harness and possibly resistor pack.

 

i agree with kensai replace the resistor and wiring harness BEFORE pulling the dash apart

 

+ 2 on that!
