Exterior Lighting Systems Description and Operation: Headlamps: Notes

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

The turn signal/headlamp switch lever is located on the left side of the steering column. A twist-type knob on the end of the switch lever controls the operation of the parking lamps and headlamps. A solid tone will sound as a reminder if you open the drivers door with the key out of the ignition and the park lamps or the headlamps on. When either the parking lamps or headlamps are activated, the following lamps also illuminate:

The tail lamps
The rear license plate lamps
The instrument cluster assembly lamps
The cigar lighter lamp
The I/P ashtray lamp
The manual selector lever lamp

Voltage is applied continuously to the HLP relay pins 2 and 4 through the 30 A H MAIN fuse. The coil is energized when the daytime running lamps control module is active in normal park or headlamp operation. When the coils are energized current flows through the HLP R and HLP L fuses and then into the lamps mentioned above.

The instrument panel and instrument cluster assembly illumination lamps intensity is controlled by the I/P lamp dimmer, instead of remaining at 100 percent.
