I have a '96 STS. None of the brake lights/running lights are working except for the strip/3rd brake light(s). The "brakelight" fuse is OK. I checked the bulbs and they're all OK too. Would this have to be wiring issue? Thanks
It was the ground. The ground wire in the trunk on the left side under the carpet. I took it off and the metal was actually painted (at the factory I guess), so I sanded it down to bare metal, put it back and they all work. Who'da thunk that it would go "bad" 13 years later?
