1. Move the ceiling light switch in the DOOR position.

2. Turn the ignition switch to ON (II).

3. Watch the ceiling light and the door indicators on the gauge control module.

Do the ceiling light and door indicators come on when the door is open, and go off when the door is closed?

YES -

Substitute a known-good under-dash fuse/relay box and recheck. If the symptom goes away, replace the original under-dash fuse/relay box.

NO -

Check for an open or high resistance in the wire between the MICU and each door switch. If the wire is OK, replace the door switch.
