Question about 1993 Toyota Corolla
Light comes on on the switch but air con pump is not engaging. Seems to be no power to the pump unit.
Hello. Thnaks for choosing FixYa for assistance.
The A/C compressor will not engage (get power) if there is not sufficient freon in the system. There is a pressure switch that opens, and eliminates power to the compressor (pump) if there is not enough freon (which creates pressure), to close the switch and allow the current to flow to the compressor. Check for leaks at the condenser (in front of the radiator).
That is the most common place for leakage to occur.
The graciousness of a FIxYa rating for my assistance would be greatly appreciated. Thnanks in advance.
