I suspect an ignition switch problem, but would like a second opinion. As of this evening, my power brakes, turn signals, and climate control are all dead in my 1992 SC with both dash board brake lights on. I looked through the owner's manual hoping to identify a fuse common to all of those and came up empty. All fuses under the hood look intact and the bigger ones under the dash do. I haven't checked all of the ones under the dash. Do the other electrical problems differentiate this from an ABS accumulator problem?
