The wiring harness melted in. I have most of it repaired, but I have no A/C . I can turn it on snowflake lights up but wont engage compressor.
I can however engage the compressor with my HP tuner through Obd2 port. I can't figure out which wire coming out of the back of the climate control unit needs to be replaced. Do you have a schematic for the back of the unit? It has the dual climate and auto feature.

Good afternoon,

I attached the wiring diagram for you of the A/C system for you to view.

I enlarged it so you can see it better.

Let me know if you have any other questions.
