Turn signals hazared signals and brake lights dont work

Most of the time the problem is in the turn signal switch. The third brake light circuit bypasses the turn signals.
Someone would need to check brake light power in and out of the turn signal switch.

Get a schematic and trace out the power source to those devices not working.

does the 3rd brake light in the back window work? check fuses if fuses are OK and the hazard lights work, then the turn signal switch may be bad. I dont know what your sons suburban (trailer?)has to do with your navigator?

i am CONFUSED? you say they dont work, then you say "when you press down on the brake that the switch for the lights causes them to go off instead of turning them on when messing around with it but couldnt figure this out"........ if NO brake lights work, then check fuse 23. . if the fuse is GOOD then check wires at the brake switch. Orange should have 12V, when brake pedal is pressed then the WHITE should have 12V and lights should be on. the center rmounted stop light (BACK WINDOW) has 2 bulbs, make sure they are good. The center light is wired differently. If the center light works but brake lights do not, the turn signal switch could be bad. I assume THE TURN SIGNALS are OK? IF the turn signals are working OK, the wiring between the turn signal switch and the brake lights is GOOD

could be brake light switch but i would be more inclined to think the signal switch is bad, the brake light circuit goes from the pedal to to the turn signal switch then to the taillights

Fuse gone somewhere

If the third brake light works and the regular ones don't, it is most likely a bad turn signal (multifunction) switch. The switch is able to kill the brakes lights to run the turn signals, and in rare circumstances does this. I've seen it several times. It could also be wiring, especially near the turn signal switch, but it is usually the switch.

well u have two seprate problems the hazards and turn signals have a flasher that needs replacing if the fuse is good on the fuse box marked signals .and there is a brake light switch under the dash board near the brake pedal it has two wires on it check the wires make sure they are connected if so replace the brake light switch

I have a 93 4-door grandmarquis and everything works but the brakelights.
I was told that the gear shift is possably tied into this because the gear shift is loose.Is that true?
And what do you suspect is the reason the brake lights dont work?

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.
