Brake lights aren't working?

Post by Mo Power » Wed Jun 04, 2008 2:13 am

OK I was wondering because I don't see exactly why they aren't the bulbs are good and when I turn on my headlights the back will light up but just the drivers side for some reason. But my question is is there a relay thats under the dash and then runs on the side of the rocker to the back? Help would be great for both of my problems

How about the turn signals? or emergency hazards?

I think also that most of the wiring runs thru the trunk,underneath the rear seat and to the front. At least mine does.

There is a connector in the middle of the harness in the bumper that could cause this if it is loose. It is located over the licsense plate.

Well my turn signals work perfect it's just the brake lights and headlights.
