2004 Escalade EXT
My A/C is just blowing air from the vents. It is not hot air...just warm air...like wind. My heater works fine. I did replace a blend door actuator about 2 years ago. I figured it needed some refrigerant this time, but it is actually showing too much refrigerant. The line coming off the accumulator is cold as ice! I placed a gauge and hose on the low pressure line and the gauge goes from low to high as the vehicle is running with the A/C on full blast. It goes to high charge and then it drops to low charge after the compressor clicks off. It does this repeatedly. I don't think it is normal the way the compressor is constantly clicking on and off, but I am not sure. I will appreciate any suggestions.
