Park, Tail and Marker Lamps

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The park, tail, and marker lamps, including the license lamps, are turned ON when the headlamp switch is placed in the PARK or HEADLAMP position, or anytime the headlights are requested. The underhood fuse block supplies battery positive voltage to the PARK LAMP relay switch contacts and coil. When the park lamps are turned ON, the body control module (BCM) energizes the park lamp relay. Current flow is from the PARK LAMP relay through the parklamps LH fuse and parklamps RH fuse to their respective park and marker lamps and to ground.
