Hopefully someone can help me out... Due to a military deployment, my '02 Jetta TDI sat for several months without being driven. When I returned, it started right up (after a jump start) and ran perfectly fine, except no AC.
The console button illuminates, the cabin fan blows, and the radiator fans both operate, but the compressor doesn't engage.
I ran battery voltage to the compressor and the clutch does click.
I tested the coolant temp sensor and the fans will run properly (both low and high speeds).
The high pressure switch connector has 12 vdc at pins 1 and 3.
After all those tests, could it still be the Fan Control Module? Or, is there another test I can try, without having any pressure gauges?
Should I try to add a can of R-134?
Any assistance or recommended gurus in the Northern VA area would be greatly appreciated...
