Brake lights dont work

Thanks for choosing FixYa Rick and welcome. You probably have a bad brake switch. It is located right above the brake pedal in the cab. The pedal hits the switch and activates the brake lights. It is a round looking chrome cylinder usually. Change it and the brakes should work. It cost 10$-30$.

they are fussed separately possible both low beam brunt out really

It could be a relay.. Find the location in your manual..

Have a great day !

The brake lights are routed through the signal light switch.
Looks like that will be the next switch to replace and the problem.

check the fusse for the brake ligt and the righht and left rear lights. also check the brake switch white is located underneath the dash board an over the brake pedal

I have a 2001 Ford F150, my brake lights dont work. Ive replaced the bulbs, checked the fuses,and the brake switch on side of the brake pedal was replaced. I still dont have any brake lights. My third brake light works fine, along with my running lights,flashers, blinkers.

check the fuse for the brake lights. The brake lights and siganl lights use the same bulb filament. The parking and running lights use a dimmer filament in the bulb. There are 2 filaments.
Your brake lights work through the multifunction switch which operates the signal lights. If the signal lights work, you may have a bad brake lamp switch which is on your brake pedal arm.
Let us know what you find.

It's most likely the breaklight switch. it's a common problem in the cateras.

Could you take out a bulb and with a testlight/probe check that you do in fact have power to that circuit .Also check that they are the correct bulb for that application I have seen people put indicator bulbs in where therse supposed to be a double filament bulb.Does the base of the bulbs lead contacts line up with the two steel terminals inside the plug?

it sounds like you need a new brake light switch its down by the brake pedal
