'02 95 ARC 190K mi on the clock, original compressor (I think). Air conditioning Compressor Clutch engages and spins when switched on, No Cold Air. Went to add R-134 and when connecting to low pressure port (the only one the gauge can connect to) the reading is in the near max "RED" zone. disconnected w/out adding anything and went "Hummmm???" Anyone done this fix?
