The problem is with the brake light switch which is located underneath the dashboard attahched to the pedal support bracket. It is either broken or needs adjusting so that the plunger is fully depressed when the pedal is in it's normal resting position.
That being said, if you replaced the bulbs recently and afterwards is when you noticed the problem check the bulb numbers and make sure that they are 1157's because even though they might look identical there are a fe different types of bulbs, some of which can, in this situation, touch both relay contacts causing your problem.
my back brake lights don't work, but the brake light on the back door does what could be wrong
IT'S PROBABLY JUST A PROBLEM WITH THE PRINTED CIRCUIT BEHIND THE DASH.
whats wrong with them??
=I don't know about the brake lights. I know that most cars, when you turn it off and get out, the head lights and main backlights stays on for a while but then goes off. The brake lights? Maybe it's the way that car is or something is wrong with the brake or you have it on wrong.=
Maybe it is not connected properly or you bought the wrong type of bulb.
wrong bulbs or bad earth
The bulb is burnt out. If the problem was a fuse, then all brake lights and probably the dashboard lights would be out as well.
Check the brake switch at the pedal.
Normally this is an indication of a defective brake light switch.
It is important to pay attention to the warning lights on the dashboard. When the ABS and brake lights flask that means there is something wrong with the brake system.
And 'appen the brake lights come on when you switch on the side lights? Someone has swopped the wiring over... or forced the bulbs into the sockets the wrong way 'round!
Brake light switch near brake pedal
I tried all the fuses, the parts that under the brakes I checked that. All lights come on and working except the brake lights no break lights.
This usually means a bad or wrong bulb in the tail lights
Have you checked all the lights? Reverse lights, tail lights and brake lights?
It sounds as if you have an electrical problem that needs to be checked. You may even have the wrong fuse for your brake lights.
ABS system is inoperable and there is something wrong with the non-ABS part of your brake system.
Its the brake switch on the brake pedal. Its a plunger like switch, its usually the only thing on the brake pedal. Its pretty easy and cheap to change.
The problem points to the directional/lights and hazard switch. The brake light wiring is part of that circuit.You can buy the switch after market it is about $70.00.
What year is the Ford Explorer ? There could be a separate fuse for the lower brake lights
check and/or replace brake pedal switch.
You have a short to ground in that circuit.
