Interior Lamps

Voltage is supplied at all times from the CTSY Fuse 3 to the Courtesy Lamps, Dome Lamps and UP Compartment Box Lamp. The Courtesy and Dome Lamps turn on when a ground path is provided by the Headlight and Panel Dimmer Switch or one of the Door Jamb Switches.

The I/P Compartment Box and Vanity Lamps have their own switches that provide ground paths when their switches close.

Underhood Reel Lamp
Voltage is supplied at all times to the Underhood Reel Lamp from the Horn Mini Fuse. When the switch is closed a ground path is provided.

Component Illumination Lamps
When the Headlamp and Panel Dimmer Switch is turned to the PARK or HEAD position, voltage is applied through the PARK LPS FUSE 9 and the closed contacts of the Headlamp and Panel Dimmer Switch to the Components Illumination Lamps. Since all of the Component Illumination Lamps are grounded G200, they light.
