Dome Lamp: Initial Inspection and Diagnostic Overview
1. Check to see that the HORN-DM Fuse is not blown. If fuse is blown, locate and repair short or source of overload. Then replace fuse.
2. If only one Dome/Stepwell lamp does not operate, INSPECT wires at lamp socket, check for poor bulb/socket connection or REPLACE bulb.
