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.
