Park, Tail and Marker Lamps (Export)
WARNING: This page is about a different car, the 2002 GMC Savana Special, 2002 GMC Savana Camper Special, 2002 GMC Savana, and 2002 Chevrolet Chevy Express. 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 ON position. The PARK LPS 20 A fuse in the IP fuse block supplies battery positive voltage to the front park lamps and side markers through the normally closed daytime running lamp rear park lamp relay. Current flow from the DRL rear park lamp relay is license lamps, and the LH and RH 5 A in-line fuses to the rear park lamps. The front park and marker lamps are grounded at G108 and G109. The rear park and marker lamps are grounded at G400 and G401.
