Air Conditioning problem
1997 Audi A6 6 cyl All Wheel Drive Automatic 115000 miles
----------------------------------------------------------------
ac will cycle on for 3 seconds, then off intially. will not cycle on again. "compressor on" snow flake will light and then turn off. can't find charging (low side) port for 134 coolant. any help greatly appreciated.

The best advice I can give is take your car to an A.S.E. certified repair shop for a diagnosis. The cost is nominal and is often applied to the repair.
