But that cold air turns warm fairly soon after because the high side pressures build to the point that the high pressure switch shuts off the compressor clutch. Once pressures equalize, the high pressure switch allows the compressor to start up again. The cycle repeats over and over, providing a short period of cold air, followed by warm air.
Where does the cold air come from in a car?
