A/C Cycling Switch

AIR CONDITIONING (A/C) CYCLING SWITCH

The A/C cycling switch is used to prevent icing of the evaporator core by cycling OFF the A/C compressor clutch when the suction pressure in the low-pressure side of the refrigerant system drops below acceptable levels. When the A/C cycling switch circuit is open, the PCM will disengage the A/C compressor clutch.
