You know that might be the newer comp that has the clutch engaged all the time. It uses a solenoid in the comp that works when you turn the AC on to let the wobble plate move and now have a stroke to comp and flow the freon. When off the solenoid lets the stroke stop wotking so that even if the clutch is engaged there is no stoke in the comp and nothing flows. I will try to see if it calls for that one. Ron
