Compressor Control: Notes
WARNING: This page is about a different car, the 2008 Mitsubishi Outlander. However, it is still accessible from the selected car via links, so may be relevant.
When operating the A/C switch
- The air thermo sensor, which senses the temperature of the air flowing out of the evaporator, deactivates the compressor at 3°C (37.4°F) or below.
- The A/C pressure sensor turns OFF when the refrigerant pressure becomes excessively high or low, thus protecting the compressor circuit. See A/C COMPRESSOR CLUTCH RELAY ON CONDITIONS .
- When the air thermo sensor is activated, and the ignition switch, blower switch, and A/C switch are ON, the A/C compressor clutch relay is energized.
When operating the mode selection dial
- The A/C will work when the mode selection dial is set to the "Defroster" or "Defroster/foot" position, or the temperature control dial is set to the "MAXIMUM A/C" position. In other dial positions, when the A/C switch is turned on, the A/C will work.
