Map Light: Description and Operation

MAP LAMP (Without SUNROOF)
On vehicles equipped with a power sunroof, a map lamp is incorporated into the power sunroof switch. The map lamp consists of the following components:
- The map lamp bulb
- A clear lens
- A two-position push switch

Power comes from the dome fuse, through the Left Instrument Panel Junction Block and then finally to the Courtesy/Reading lamp. When the light switch is depressed to the ON position, it provides power to the courtesy/reading lamp. Current flows through the lamp and then continues to G200 and G201. Pushing the switch a second time turns the map lamp off.
