Bulletin No.: 56-82-02
Date: April, 1995
Subject:
Operation of the Instrument Cluster Dimmer and Interior/Dome Lamp Rotary Wheel Switch
Models:
1995 Chevrolet and GMC Truck C/K Models
The instrument panel dimmer wheel now has two detent positions. The first detent position puts the radio display and PRNDL light emitting diode on
maximum intensity, along with the instrument cluster illumination. This is often called the "Parade Mode". The second detent will turn on the
interior/dome light.
The switch directly below the park/headlamp switch, labeled dome lamp, will not illuminate the dome lamp. Its purpose is to prevent the dome lamp
from coming on when the doors are open. In addition, it does not interfere with operation of the rotary dimmer switch described above.
