Thanks for the response...that's exactly what I did and it works perfectly!...I've been dealing with an intermittent a/c compressor cutting out for probably a couple years now. The compressor rarely worked when the "A/C" button was depressed, but more often than not if I pushed the button above the a/c button, I could force the compressor on. I've tried replacing various other easy to replace components- klima relay, coolant temp sender/switches, full throttle micro switches, etc to no avail. For some reason I dismissed the possibility of it being the pushbutton control unit until I ruled everything else out. Murphy's Law dictated it would be the last option left! Been a long time since I enjoyed a functional a/c system!
