Electrical
I've been chasing some electrical gremlins in my '71 Suburban for a while now. My brake lights stopped working. I tried adjusting the stop light switch. I've checked fuses. I've checked bulbs. I even bought a new brake light switch. Unplugged the wire from the old one, plugged the new one in and....THEY WORKED before I installed the switch. Installed it and.....no brake lights. Any help is welcome.
Also, dash lights aren't working.......😡 |

Re: Electrical
Dig out your test light and see if you have power to the switch.
I'd check the fuse because it is easy to pop the fuse when you are moving those hot all the time wires around.  With that you might also want to check the hot wire from the fuse block to the brake light switch to make sure that it hasn't rubbed on metal and shorted out.

Re: Electrical
If the lights came on when you plugged in the switch, you don't have a fuse or wiring problem.. the switch has to be adjusted correctly when you install it.. It sounds like the switch needs to be adjust farther away from the pedal arm...
