Normal Operation

WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 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 ON position, voltage is supplied to the instrument panel dimmer switch through circuit 14 (BN). The instrument panel dimmer switch then sends a variable voltage to the backlighting lamps through circuit 235 (RD/BK). The ground signal is supplied to the instrument panel dimmer switch through circuit 1205 (BK).
