    My brake lights are always on for some gawd unknown reason. the pedal is a bit loose. if i shake it violently, after a few times it justs "stuck" where the brake lites are not on constantly.

    And tips are appreciated /forums/images/graemlins/thumb.gif

    There is a tab that holds the brake switch...just bend the tab a little until the brake lights stay off when your foot ain't on the brake. I had to do that to my truck a couple of weeks ago.

    The hardest part is geting into a position to see what's what under the dash.

    On both my truck the threads on the switch were stripped. I found a small radiator clamp fixed the problem.

    any suggestions as to where to look for the pedal?

    i can get my dash of with 2 screws and cutting a zip tie /forums/images/graemlins/crazy.gif so it's no problem to gut it

    Just lay on the floor and follow the arm of the peddle up. the switch is on the bracket that hold the peddles on. WHen the peddle is released it pushes the button.
    Now if the lights are not coming on at all it's an electrical problem or the switch is bad. WIth your other problems I would bet electrical.

    Sounds like the switch needs to be pushed IN a couple of millimeters. When the plunger is depressed, the lights are off.

    Of course, this is assuming the earlier brake switches are set up like later ones (80's) in that the switch "plunger" assembly is threaded...you just kind of wiggle it and push at the same time.
