Normal Operation

WARNING: This page is about a different car, the 2006 Mercury Grand Marquis and 2006 Ford Crown Victoria. However, it is still accessible from the selected car via links, so may be relevant.

The lighting control module (LCM) supplies a variable pulse width modulated (PWM) voltage to the instrument panel switches through circuit 484 (OG/BK). The LCM uses the instrument panel dimmer switch to determine the intensity of switch illumination.
