I have 1988 Olds cutlass ciera SL. 3.8L with sudden electrical problem. One day the radio, dome light, electric locks and horn suddenly stopped working. I think this is all that is affected. Fuses are fine, and everything else seems to be fine as far as I know. Is there some master fuse that these particular things are connected to? My inspection is due this month and I need to figure this out. Thanks all!
