A/C clutch will not engauge all elect. test out OK
System Press. to high let out all press.
went to refill before even 1/2 a can in system press. to high again.
Does anybody have an idea of what would cause such a thing ?
If you have a ATC perform a byte check if you have no codes then disconnect connector at A/C Compressor and see if you have 12 volts to engage the clutch. If 12 volts is present then clutch is bad. If you have no voltage try switching a relay there should be a match you can swap with. On my 93 I had a intermitten ATC and a bad evaporator probe located inside the evap. What are your pressures on your low and high side? Hope this helps
