Stop Lamps

WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.

The HZDL fuse in the console fuse block supplies battery positive voltage to the normally open stoplamp switch. When the driver presses the brake pedal, the switch contacts close and battery positive voltage is supplied to both left and right stop lamp assemblies and to the center high mounted stop lamp (CHMSL). The CHMSL is grounded at G301. The left stop lamp is grounded at G401 and the right stop lamp is grounded at G402.
