Normal Operation
WARNING: This page is about a different car, the 2007 Mercury Mariner and 2007 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
Under normal operation, the A/C system is activated when the function selector switch is in the NORMAL A/C, MAX A/C, FLOOR/VENT, MIX or DEFROST modes. The PCM controls the cycling of the A/C compressor clutch.
