Rear Fog Lamps (Export)

WARNING: This page is about a different car, the 2003 Pontiac Montana, 2003 Oldsmobile Silhouette, and 2003 Chevrolet Venture. However, it is still accessible from the selected car via links, so may be relevant.

The rear fog lamp module requires the headlamps to be ON in order to turn ON the rear fog lamps. The HEADLAMP circuit breaker an RR FOG LP fuse provide battery voltage to the headlamp switch and rear fog lamp relay. When the headlamps are on, battery voltage is applied to the rear fog lamp module. The rear fog lamp switch is a momentary contact switch that, when pressed, provides a ground signal to the rear fog lamp module. When the rear fog lamp module receives the fog lamp switch ON input from the fog lamp switch and the headlamps are ON, the rear fog lamp module energizes the rear fog lamp relay. When energized the rear fog lamp relay provides battery voltage to the rear fog lamps. If the rear fog lamp switch is pressed again, the rear fog lamp module will de-energize the rear fog lamp relay. If the headlamps are turned OFF while the rear fog lamps are on, the rear fog lamps will turn off. If the headlamps are turned back ON, the rear fog lamps will not turn on unless the rear fog lamp switch is pressed again.
