Hi:
The blower motor not working can be caused by several things. To start, I would go to the blower motor resistor and check for power. The resistor is on the firewall. If there is power there, you will need to get to the motor itself to check for power. It's located under the dashboard. If power is to the motor and it doesn't run, it will need replaced.

This guide shows you how

Let me know what you find.

The fan blower for the front passengers quit working. The air works as well as the blower for the rear passengers. Where can I find a print for fuses?
Could it be an overload reset for the blower motor?
How big a job is it to change a blower motor if need be? Thanks. Tom

I was wondering how to go about replacing the front blower motor. What all has to come apart?I can see the motor bolts in from underneath, but I am unsure about the cover underneath.
I am a ford senior master certified technician, but I do not work on dodge vehicles very often, and I dont want to do more work than necessary.
Thank you for your time, dan

When it stops, does it work on any speed? Have you checked the motor to make sure the wires are tightly connected?

Let me know.

If it doesn't work on all speeds, is it only the high speed that it works on?

It will work on all speeds for hours sometimes days, then it won't. Normally after the car is turned off, and sometimes while driving along it stars working again.

It sounds like you either have a bad blower motor relay or a loose, corroded connection to the fan motor, or a bad ground.

Have you checked any of the items I mentioned?

"I am having electrical problems - no gauges, no wipers, cannot turn headlights off, cannot turn heater blower motor off, no aux key position, sometimes transmission will not shift to higher gear, couple other minor things. Any idea what it may be?"

First, have battery and alternator checked for proper operation, an alternator putting out ac voltage will confuse the pcm and make it do stupid dtuff.

Have the bcm checked for codes as it is the common denominator for all these functions

Pcm is the engine computer and bcm is the body control module which all body functions go through

The 2 medium setings on blower for air conditioning or heater does not work. The low and high settings do work. Is just a fuse?
