Normal Operation

WARNING: This page is about a different car, the 2004 Mercury Mountaineer and 2004 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.

When the headlamp switch is placed in the PARK position or the headlamp ON position, battery power is supplied to the instrument panel dimmer switch and the dimmer module through circuit 14 (BN). The instrument panel dimmer switch uses the parking lamps ON input and outputs a pulse width modulation (PWM) voltage to the dimmer module and the illumination controls through circuit 235 (RD/BK). The ground signal for the dimmer switch is supplied through circuit 1205 (BK).
