I have a 1993 90. Today the windshield wipers, turn signals, headlights, fog lights, rear defogger, sun roof, windows, power mirrors, and AC/Heater fan stopped working. At first I thought it was just a fuse, then I figured out that 4 or 5 different fuses were involved. Hoping for the best, I replaced them all, but I'm still having the same problem. Any suggestions? -Frank
