My blower motor resistor is going out and need to replace it . The fan speed blower motor for heater and A/C is only working on high and not the other speeds . Can anyone tell me where a diagram is for replacing this resistor?

Help, thanks Mike

 

It's definately the resistor...I just had to change one out on my Wrangler.

I haven't had to find it yet on the Ram, but according to the service manual:

The blower motor resistor is mounted to the bottom
side of the HVAC housing near the blower motor.
It can be accessed for service from underneath the
instrument panel.

Find the blower motor and there is a wiring harness going to the resistor just to the bottom right of the blower motor. The resistor is held in with 2 screws. It may be easier to remove the resistor before messing with the wiring harness. Sometimes it's tough to figure out how to release them when looking upside down. It also will help if you have the new one so you can see what you're looking for.

Good luck.

 

yah, i replaced one at the dealership but it's been about 6 months ago. it should be held in place by 2 torx screws i think. but yah just follow those instructions and you should be set. best of luck to ya

 

Thanks a bunch guys for the instructions. Everything went great and now is working fine. Again thanks for your help
