Circuit Operation - Interior Lights

Voltage is applied at all times to the I/P Compartment Lamp through the CTSY Fuse. When the I/P Compartment Door is opened, the I/P Compartment Lamp is grounded and turns "ON." Voltage is applied to the Overhead Console, Center and Rear Dome Lamps, Stepwell Lamp, and Cargo Lamps through the CTSY fuse. With the Courtesy Override Switch "ON," these lamps can be grounded by the Front Door Jamb Switches, Sliding Door Jamb Switch, or Liftgate Jamb Switches. Also turning the Headlamp Switch "ON" will ground the Interior Lights.
