I have a Chevy Suburban 2003, and the dome lights don't work either with door open/shut or using the overhead switches. I've tried the Dome Override and changing the fuses on the side of the dash, but to no avail. The odd thing is that the lights on the sides of wing mirrors work, which I thought were on the same fuse as the dome lights. Also, all 4 inside lights have gone at once, leading me to think it's not bulbs or loose connections in the roof fitting. Are there any other options I can try?
