Air Conditioning Switch: Description and Operation

A/C Switch:

ACCELERATION CUT SYSTEM
The A/C switch turns the air conditioning system ON and OFF The on-off signals from the switch are transmitted to the engine control module (ECM).

When the ECM receives a full-throttle signal from the throttle sensor during compressor operation, it deactivates the A/C relay to interrupt electric current to the compressor magnet clutch. This prevents the degradation of acceleration performance. The A/C relay is in the main fuse box located on the left side of the engine compartment.
