Tai lights won't work on my truck. Any ideas?
I have a 1995 Chevrolet c2500 truck. The headlights, turn signals and brakes work fine
but the park lights and tail lights and dash lights won't work. The signal indicator light,
check engine and bright light indicator all work. I installed a new switch thinking that was
the cause but it didn't fix the issue. I thought I heard a pop noise when I started it one day
but didn't think twice about it. Trailer lights don't work and brake controller indicates that
they are not connected but when you tap on the brakes or use the turn signal, they work
fine. I'm stumped.
