Interior Lamps Dimming: Notes
WARNING: This page is about a different car, the 2002 Buick Regal and 2002 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.
The second group of lamps include lamps which may be dimmed. This group may use a combination of vacuum fluorescent (VF) illumination and incandescent lamps:
- Ashtray lamp
- Automatic transaxle control position indicator bulb
- Fog lamp switch
- Door switches and window switches
- HVAC control head assembly
- Outside remote control rear view mirror
- Radio
- Radio control switches
- The Instrument Panel Cluster (IPC)
- Heated seat switches
- Electronic traction control switch
When the headlamp switch is placed in the PARK position, battery voltage is supplied through the headlamp switch to both the TAIL LAMP, LIC LAMPS fuse and the FRONT PARK fuse. Battery voltage is then applied through the TAIL LAMP LIC LAMPS fuse and the FRONT PARK fuse to the front and rear park lamps and the rear license lamps illuminating the park lamps.
Battery voltage is then applied thorough the rear park lamp fused circuit to the I/P dimming switch and the VF dimming components.
