Courtesy Lamp: Description and Operation

Voltage is applied at all times through Fuse 8 to the Trunk Lid Lamp, Engine Compartment Lamp, Glove Box Lamp, Instrument Panel Dimming Rheostat, and Door Switches.

On vehicles equipped with Keyless Entry, voltage is applied at all times through Fuse 8 to the "BATTERY SAVER INPUT" of the Keyless Entry Module. the Module contains an integrated battery saver relay, which supplies power at the "BATTERY SAVER OUTPUT" through the 705 (LG/O) circuits to the Engine Compartment Lamp, Glove Box Lamp, Instrument Panel Dimming Rheostat, and Door Switches. The battery saver relay is activated anytime the Keyless Entry Module receives an input signal, and is deactivated approximately forty-five minutes after the last input to the Module. Once the relay is deactivated, power is removed from all the courtesy lamps except the Trunk Lid Lamp.

If the Instrument Panel Dimming Rheostat thumbwheel is rotated to the detent position or if a Door Switch is closed, current flows through the Instrument Panel Courtesy Lamps, Dome Lamps, Underseat Lamps, Door Courtesy Lamps, Lock Lamps and the Rear Reading Lamps.

Individual Reading Lamps can also be turned on by the individual Reading Lamp Switch if the Ignition Switch is ACC or RUN.

Vanity Mirror Lamps have voltage applied to the individual switches at all times. When the mirror cover is opened, current flows through the 2 amp fuse and resistor to provide subdued lighting to the mirror. Closing the mirror lamp intensity switch applies full battery voltage to the lamp circuit and the brightness of the vanity mirror lamps is increased.
