The A/C blower will not come on heat or A/C. Fuses are okay, the blower checks good and runs with jumpers. Have not found the HVAC power module so I can check volts.

I am assuming you have not done self diagnostics which you should do it is in picture because it may not be that module. That module is by blower motor we have no picture. See picture for self diagnostics then get back with codes.

Hello,

I find two diagrams (below) that can show different locations, one is under the dash on the passengers side while the other is under the hood on the passengers side.

Let me know if you find it.

Please let us know what happens.

Cheers, Ken
