I’m not sure if this is the place to ask, or in the “electrical” section of the technical page, but here goes. My 75 Blazer headlights work, but the parking lights do not. When I turn on the parking light switch, the fuse burns out immediately. All the bulbs are new and I don’t see any obvious issues like bare wires, so I’m not sure where to look next. Is it possible that the issue is in the headlight switch itself? Any help would be appreciated. I’ve owned this Blazer since 1980, but I only drove it 14 months before I parked it when I joined the Marine Corps. It has been off the road since February 1982 and I’m close to getting it back.
