Normal Operation
When a door or the liftgate is closed, the ajar switch grounds the circuit from the vehicle security module. The vehicle security module monitors the door ajar switch status and transmits an interior lamp on signal to the instrument cluster indicating an entry point is open. The instrument cluster energizes the interior lamp circuits, lighting the interior lamps.

Possible Causes
- vehicle security module
- instrument cluster
- fuses
- circuit 3049 (BK/LG)
- circuit 1203 (BK/LB)
