Re: Cigarette Lighter and Blower Relay Wiring Questions
Its my experience that GM typically doesn't fuse the cigarette lighter which can be problematic. I had a lighter short out internally while driving down the freeway in my old S10.
I don't smoke and never used the lighter but out of the blue one day smoke starts billowing out from the dash area where the lighter is. Needless to say I made a sharp right to the side of the road and started tearing wires out of the dash.
I believe that the cigarette lighter and the high speed fan power can share the same connector at the fuse panel. The link explains the circuit as well as has the wiring diagram.
