went to work in the morning, had the heat(defroster) on and everything was fine. got in the vehicle this afternoon and tried to turn on the a/c. Nothing came out of the vents. It sounds like the compressor is engaging and the lights on the control panel seem to be working also. What could be causing this problem? Any help would be appreciated.
