go to radio shack and get a really cheap "test light". It looks like a probe lookin thing with a light bulb inside. Take it and a friend of choice and put the alligator clip to something grounded. Put the probe in the middle of the bulb socket (take the bulb out 1st) if the little light comes on when the brakes are on then the wiring is fine. If not, go to the next power place--the fuse box. You don't have to pull the fuse to check it w/ a test light. Just put the probe on the top of the fuse where the metal shows on it. Do BOTH sides of the fuse.If the light does not come on both time-- then change the fuse. I think there's even a fuse under the hood for brakes but don't quote me on that. Also check the little switch that the brake pedal is connected to. Good luck. BTW-- Do the blinkers work????
