Question about Cars & Trucks
My brake lights and turn signal lights do not work
If an American car- Ford, GM or Chrysler-they all have one thing in common: the brake lights and the rear turn signals share the same circuit. The brake light wire is routed through the turn signal switch. If neither work, it's likely you have a bad turn signal switch.
Japanese and European cars keep the brake light circuit separate.

SOURCE: brake lights and turn signals
I had this same problem on a 1995 Lincoln Towncar -- thought I might have to replace the Signal Switch - then it was suggested to check the ground for this wiring. However I was told to check the HAZARD SWITCH. The Hazard Switch was not On or Off it was stuck in the middle. Simply pushing it up and down correct the problem. I was also told that maybe a little WD40 on the HAZARD SWITCH might help.
This is an easy try me first fix. It worked for me and cost 0.

I had this problem, and to be honest, it happened to the left side about a week later...it's the board that the bulbs plug into...it's a very common problem with this model. So popular that you can normally get the socket board off the shelf at a parts store! it's extremely simple to replace, and I replaced all the bulbs at the same time!
