My 1992 sundance's dome light, radio or rear defrost is not working. i check fuses...all good. where do i go from here.

This is a good one. Get your hands on a wiring diagram. What you're looking for is a common wire that possibly links the radio, dome light, and defroster. You're looking for possibly a common power wire. Look for bad grounds under the dash. Mainly look for a common wire between the components. I have seen if one thing goes bad, it would effect things that you wouldn't think had anything to do with it. Honda is good about that.

check fuse #4 in the fuse box uner the hood....it is supposed to be a 20 amp fuse ....check it for being blown and make sure there is power going to it.

SOURCE: Where is the fuse box on my 1992 plymouth

You're fuse box is located under the dash, left of the
steering colum. There is also a chime module located
under the dash, to the left of the glove comp.
Also, I believe the chimes share a fuse with the brake
lights. Hope this helps.

If bulb is good then pin switches in the doors may be going bad.
