Park, Tail and Marker Lamps
WARNING: This page is about a different car, the 2004 Pontiac Sunfire and 2004 Chevrolet Cavalier. 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. The EXT LAMP fuse in the IP fuse block supplies battery positive voltage to the headlamp switch. When the headlamp switch is placed in the PARK or HEADLAMP position, current flows through the headlamp switch to the park, tail and marker lamps and then to ground at G102, G302, and G304. If the park lamps are turned ON, they will remain ON until turned OFF or the battery runs dead.
