1999 Volvo V70 Question: Air Condition worksd for awhile and cuts off



skipper4, 2.4L 5 Cylinder, Huntington Beach, CA, July 18, 2010, 23:26

Air unit runs ok until wheather temp is hot. Will run for 20-30 min and cut off. If turn unit "off" for approx 10 min, will work when turned back on, then will go off again. Unit does not have a diagnostic code.

    This can be due to low refrigerant, a bad pressure sensor or the A/C clutch is failing when it's getting hot. It will require checking the voltage signal to the compressor when the A/C starts blowing warm air.
