My Lexus was in the repair shop for touch-up paint on roof and rear side panels, and a windshield replacement. Over the past 30 days, I have lost power to the dome light, reading light, courtesy lights, door locks, side view mirrors, security system, remote key lock, trunk release, and radio antenna. I replaced the Dome fuse several times, and it sparks and shorts out. Do you know where the problem might be, and how to fix it? The repair shop will not claim responsibility, so it is my nightmare to fix.
