What Does This Ac Switch Do?
The AC switch on the instrument panel activates and deactivates the air conditioning system by energising the AC compressor clutch relay and enabling the blower circuit. Some units also incorporate mode selection for recirculation, fresh air, and fan-only operation.

If your machine is showing any of the following, a faulty ac switch may be the cause:
- AC system not activating or deactivating when the switch is pressed
- Compressor clutch not engaging despite the switch being on and refrigerant pressure being correct
- AC switch indicator light not illuminating when the system should be active
