ac help please

[Goat]

I have the digital ac controller in my tahoe. It turns on and the blower motor dont so we replaced the resistor and now it isnt getting power between the control unit and resistor. Father in law checked it. Every fuse and wire looks great. Did I miss something? blower will not kick on at all..

I changed the climate control out to one that I know is good and it does the same thing.

Could the resistor be bad?

could be but we put a brand new one in it

Check the connector on the resistor and blower, my connector went bad (over heated) and would cut out randomly, bumping, wiggling and eventually kicking it would set it right again. I did splice in a replacement eventually.

Thread from 2022. It's all good. You might actually get a response when we get some of the old members back.
