No power to motor fan resistor?

Hi,

I attached the wiring schematic below for a manual climate control. If you have an automatic climate control system, let me know.

As far as power to the resister, there is a 40-amp fuse and a blower motor relay. Both are located in the power distribution module under the hood,

Note that this vehicle has an integrated power module. These have a history of connector pin failure, so that is something to keep in mind.

Take a look at the schematic and let me know if it helps and what you find.

Take care,

Joe

See pics below. Note: I cut the schematic in half to make it readable for you. I did overlap the two so you can follow from one to the next.

Hi:

Do you have power to the blower motor resistor if you jump pins 30 and 87 at the blower motor relay?

If I had to guess, I would say the integrated power module has failed. Check the connectors to it under the hood to see if any are damaged, corroded, or actually broken.

Let me know.

Joe
