1. Move the ceiling light switch in the MIDDLE 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 each door is opened, and go off when each door is closed?

YES -

Substitute a known-good driver's (or passenger's) under-dash fuse/relay box, and recheck. If the symptom goes away, replace the original under-dash fuse/relay box.

NO -

Repair an open or high resistance in the wire between the driver's (or passenger's) MICU and each door switch. If the wire OK, replace the door switch.
