1990 GMC S15 Jimmy QuestionsHow do I change the break switch, what does it look like, and where exactly is it located on a 1989 S15 Jimmy? (1 answer)
I brought a part but It doesn't seem like right part. It's long, with two terminals on one endend, and a threaded end with plunger. The same switch is on the front of my break shaft not the back, that's why I think I might have the wrong part.
We replaced wires and plugs already. It showed no warning b4 it died. Just didn't start back up one day.
Checked fuse, i am getting continuity up through the push button on turn signal lever, replaced small black box under dash, left of steering colmn. i have great vacuum to throttle actuator. please help!
