car repair help
i have a 2000 grand prix the blinkers work the passenger side the back tail light on the driver side dont work had water in it changed the bulb and it worked but now the driver side brake light dont work need advice.
Have a buddy apply the brakes, turn on the lights, use the blinkers, in every combination. With the harness removed at each light, test each lead, one by one, with a cheapo volt tester. You're checking for voltage and a good ground at every bulb contact. You need to do the methodical testing to find it. It could be a bad socket, loose ground, anything. Worst case is that you have no voltage at the bulb, and that means the brake/turn signal relay is bad, and it's not hard to replace.
