I just bought a 1995 850 sedan. Runs and drives good, problem is that none of the interior lights come on (dash cluster, heat and ac controls, radio etc all work fine) when the doors are opened up, or the switches are turned on. I have replaced all the bulbs, checked the fuse and even replaced it even though it showed good. I'm at a loss and I work at night so lights would be really nice.

 

The dome light assembly might be bad.

 

Darn it, Tech beat me to the punch again! We had bad dome light assembly when we bought our 95 a few years back. A couple of the switches were not making contact. Take the assembly off and check it out, I bet that is your problem
