HVAC controller not working
I just changed out my alternator last week and every thing works except my HVAC. No screen, buttons or lights. I don't know if there is any connection, but that is the only work that had been done.
I tried another box that the seller said worked when pulled from another rig. Does anyone have a schematic that shows where the wires from the 12 pin plug go. I need to find where the switched power comes from. The truck is a 92 ECSB K1500. Thanks Steve
