WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2009 Jaguar XKR, 2009 Jaguar XK8, 2008 Jaguar XKR, 2008 Jaguar XK8, and 2007 Jaguar XKR. 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.
