I have a 97 Geo tracker. I had to replace the under dashboard and most of the motor wireing harness. Since then the AC doesn’t work. It did before the swap. I apparently missed a plug along the line somewhere. The indicator light on the dashboard switch doesn’t light up. Tested the switch and it’s good. There is no voltage to the plug. I checked the plug on the harness at the engine compartment. green and yellow wire feeding from the firewall have 12 v on them. When I unplug and plug the plug up the cooling fan will momentarily come on. This is with the ignition on and engine not running. Could that plug be bad?what would be common that I can run power to the system. I’ll want to rig a switch to power the system. Any suggestions to get it running would be great. I’m not pulling the dashboard.
