Brake lights not working on 2002 durango Bulbs have both been chaged 3rd one works as does tail lights What is wrong?
Did you try switching out the bulb's socket? On my 2002 durango, it was a simple fix. (Bulb change didn't do it.) I got a new bulb socket from our local parts store, screwed the old one out, and the new one in, with a new bulb, and she fired right up. Well, almost. I had to fiddle a little, to screw in in just right to make good contact. Cost about five or ten bucks.
Then fix them. Start by checking the bulbs - those are dual filament bulbs, and it's possible that the filament for the brake lights was compromised. If those check out, see if you have power to the brake light circuit with the brake pedal depressed by using a test light. If you don't have power, what I'd do next is find the relay and test that. Remove the relay, check for power at the 30…
How do you fix the problem of a 97 expedition brake lights not working but all other lights are working?
The brake lights and tail lights are separate wiring systems. Even some of the bulbs may have two separate bulbs in the same glass housing. If the bulbs are in fact working, then the next step would be to test the brake switch under the dash. When you depress the brake pedal the switch is pushed creating a connection to turn on the brake lights.
