The compressor works and there is refrigerant in the system, I have got power at the relay but no ground, I can start the compressor by jumping it, what wire is for the relay ground, and where does it go?
Does it pass through the PCM before going to the switches?

the relay is controlled by the front control module to when it goes on and off.which may be part of the TPIM module under the fuse box. so it is either a control or TPIM module problem which a mechanic will have to scan for codes to find the problem. It can also be a can/bus problem which means one is not talking to the other or some other module like the HVAC so It will not work.
