Hello, all. The car in question is 1993 940 Wagon with manual climate control (no climate control, I should say, just old-fashioned knobs). The A/C compressor does not kick in at all. The charge seems to be ok, but I just never see or hear the clutch kick in. Needless to say, there is no cooling. I have read on the FAQ about the PC board on the controller having a problem with weak traces. Took the control unit apart this morning and was disapointed to find that the PCB is fine, no sign of burnt traces or loose solder joints. Too bad, because I am very comfortable fixing loose, cold and otherwise bad solder joints or broken traces or anything else that requires a soldering iron. So, how do I troubleshoot this? I looked at the compressor and saw only one wire going to it. Should I check voltage on that? How do I characterize the problem? Is it mechanical or electrical? I am pretty certain that the charge is good in the system, but will appreciate advice on how to make sure. Before quiting the A/C was intermittent cutting in and out, which I think is normal in really hot weather. This winter the car had an encounter with a deer, which destroyed the condenser and after replacement and charging the system, the mechanic said he did not see voltage at the compressor. I did not verify this, but just deferred it to warmer months (now). Then I read about the controller PCB problem and thought that I had a handle on the issue since the symptoms seemed to match. This morning proved me wrong and I am on a quest once again.

Appreciate in advance any and all wisdom.
