Brake light problems
I'm new to the site, I've got a 1990 C-4 with no brake lights across the back, I've got tail lights and turn signal just no brake lights except for the one above the rear hatch, it works.
I've replaced the turn signal multi switch and also the brake switch but still no brake lights. Oh and yes I checked the bulbs. Once I changed the turn signal switch I got brake lights on one side
so I took the car for a drive and when I got back they were all working , then left again and had nothing when I got back and nothing again since. I thought maybe a ground problem
but wouldn't that be a problem for all the lights across the back and not just the brakes? Any ideas?
