I have this same problem with my 95 SLE. See my post from years ago (Head/Park Lamp Switch). The switch gets too much power and therefore heat from something. It gets scorched, the harness actually deforms from the heat, and I lose my dash lights. Eventually, I lose the tail lights too. I found that if I keep Twilight Sentinel (automatic lights) on, everything works OK, for years I might add. I presume you have this option. But, I have found no help from the wiring schematics or my old post on where I should look to find the source of the problem. There are miles of wires in a car... I suppose I would have had an electrical fire by now if it was going to happen (I've got 262K), but I would really like to solve this mystery and prevent such a nightmare for me or anyone else.
