To make it short. My AC Clutch relay will not work because it has inadequate voltage. This appears to be ground switched through the controller. There is 12v present on the other side of the circuit and adding good ground to the relay will cause it to work properly. So, this appears to be a bad connection or corrosion. The blue/white wire from the relay to the controller is good. I am trying to determine which wire is used by the controller for ground, so I can check that for voltage drop....although the blower relays work fine, so unless there are multiple grounds to the controller then perhaps it is bad. However, when the AC switch is pushed in, I get a signal on the blue/white wire.
I hate to replace the controller but may have to do so. I can find nothing that shows all the wires in the harness connector to the controller. An the best schematic I have found shows a different color wire going from the relay to the controller, making me no trust any of the other info.
A schematic, any thoughts, or experiences, would be appreciated.
