Air Conditioning Compressor Solenoid Valve
WARNING: This page is about a different car, the 2011 Jaguar XKR, 2011 Jaguar XK, 2010 Jaguar XKR, and 2010 Jaguar XK. However, it is still accessible from the selected car via links, so may be relevant.
The air conditioning (A/C) compressor solenoid valve is integral with the air conditioning (A/C) compressor. Operation of the solenoid valve is controlled by the automatic temperature control (ATC) module using a hardwired drive current of differing values. By controlling the flow of refrigerant through the compressor, the solenoid valve can control the air conditioning (A/C) system pressure and the evaporator operating temperature.
