Brake light switch?

Get under the dash Switch on the brake arm may have went bad. If your car has cruise control there will be two switches. The one with just the plug is the brake lights. The one for the cruise will have a plug and a vacuum line.

Could be the sending unit in the tank went bad for your gauge problem.

One other thing I thought of. One time a buddys van was doing the same thing. Ended up the hazard switch was pushed in but he didn't know cause the flasher was burned out. Pulled out the hazard switch and wa la Brake lights.

No hazzards? Your switch in the clolum may have went out. Do you have turn signals? Brake lights, hazzards and turn signals all use the same circut.
I have seen the hazzard, turn signal switch go bad and cause this condition.


I would still check the switch on the brake arm with a tester to make sure contacts are closing.

It's sounding like the switch in the column to me.

Did you try unpluging the switch on the brake arm jumping the conections on the plug?

Switch flashers with the turn signals. you know thats working. Not going to fix the brake lights but will help narrow it down.

You can also unplug the harnes to the column and check conections.
