Parking lights problem

[joehfd]

Ok Guys heres a good one,
I've finally got the[u] engine problems fixed on my 95 S10 blazer and i guess i havn't gone through enough misary. I went out to the car last Saturday and my parking lights were on, everything was off so i figured it was the switch so i replaced it and everything was good. Well I went out to the car tonight and they were back on.....Question is where do i begin to trouble shoot I did notice that when i put the car in drive the rear hatch would go off but that seems to have stoped for now

If you have an aftermarket alarm system, aftermarket keyless entry, trailer hitch wiring, etc etc, I would check there first. Most aftermarket add on accessories cause an electrical problem eventually, especially if it was installed by a rookie. If there are no aftermarket accessories installed on the vehicle, I would pull the fuse for the rear hatch (being you’ve had a problem with that) and see if park lights still come on by themselves. If that fuse doesn't make the problem go away, pull the fuses one at a time until the problem disappears. That would be the circuit to trace for a B+ short to the parking light circuit.
