It can't be a relay causing this as I have remvoed them all in an effort to troubleshoot this problem.
All AC/Heat controls, fuses, ECM Computer, relays have been removed; and their sockets left empty...still the clutch energizes as soon as I connect the Truck's 12Volt battery...
I must now un-plug the compresor clutch coil or unplug the pressure cycleing switch on the receiver-dryer to drive the truck. When parked I must remove the + battery cable...or the battery will run into the ground in very short order.
Very Very Strange Indeed !
