This question has been driving me crazy since this summer.
The A/C on my car works fine until I am forced to slow down or come to a stop, when this happens the A/C quits blowing cold and starts blowing extremely hot air, hotter than the highest heater function. My theory is that the phenomena happens in conjunction with a downshift in the transmission but beyond that I don't know what to do. The dealer wanted to start throwing parts at it but that can be very expensive without knowing. The compressor seems to be ok.
Help would be appreciated.
