In my 2004 GTS, my A/C light is flashing Green. I thought it could be the coolent level, so I bought one of those compressed air/freon cans. Connecting it I find that is seems to be topped off already because it just sprays everywhere instead of entering the tubing...and the pressure gauge is high. Im wondering if there is anything I can do to tell if my AC compressor/condensor is bad without taking it in somewhere. I know HVAC work will definitely be outta my league.
