WARNING: This page is about a different car, the 2003 Ford Pickup, 2003 Ford F550 Super Duty, 2003 Ford F450 Super Duty, and 2003 Ford Excursion. However, it is still accessible from the selected car via links, so may be relevant.
The instrument cluster and the panel lighting system consists of both dimmable and non-dimmable (fixed) illumination sources. The instrument cluster and panel lighting system is powered through the headlamp switch and the instrument panel dimmer switch (part of the headlamp switch). The dimmable lighting illumination intensity is controlled by the output of the instrument panel dimmer switch.
