Anyone know what controls the wire to the AC compressor clutch? The wire is energized whenever the key is on. I replaced the drier and low pressure switch. The interior heater/AC switch and push button vacuum lines seen to be functioning properly as well. The fan switch is in the off position and the push button is in the off position also. Just can't figure out why the compressor wire would be energized all the time. Any comments are appreciated!
