Air Conditioning: Notes

The air conditioning only functions at ambient temperatures above 0 °C. At temperatures lower than this, the pressure in the system is too low and the compressor is never engaged.

The air conditioning only functions when the engine is running. It functions regardless of engine speed (RPM) and vehicle speed. The blower fan must also be operating before the climate control system can be engaged.

The air conditioning system has only two positions, off and on. If it is too cold in the passenger compartment, the temperature can be controlled with the normal heat and blower fan controls.

Air conditioning is based on the same principle as that used in refrigerators.
