Do you have power to the compressor? Do you have freon in the system?

Roy

Do you have any pressure in the system as you need at least 25-30 lbs to engage the compressor

Roy

Yes its full

Well, you have replaced many parts with no result. It is time for help from a shop to at least diag it for the failure. At this point, it could be a wiring issue.

I had the same issue with my taurus it turn out to be the ECT sensor it looks like a temp sensor, it only has one wire coming from it make sure its plugged in and wires are intact
