BRAKE LIGHT WONT WORK. APPEARS THAT PEDAL SENSOR IS JAMMED

which make of car and year search finds you the part

are you up to DIY and purchase of parts fitting new parts

its sensors near the top of the brake pedal under the dash

P0571 Cruise Control/Brake Switch A Circuit Malfunction
P0573 - Cruise Control/Brake Switch A Circuit High

C107C - Brake Pedal swithch 1/2 Stuck
C107D -brake pedal switch 1/2 correlation

some examples of locations cruise/brake switch

brakes locking on is an indication of a failing master cylinder and not allowing the brake fluid back to the reservoir
At this point I would suggest a visit to an accredited professional brake shop for a proper diagnosis and an explanation of what would cause the fault
I am thinking that the rubbers in the master are enlarged and are jamming the return of the pistons in the cylinder

There are two switches on the brake pedal, one for brake light, and one that kicks out the cruise when you hit the brake. That switch is closed when depressed (ie; brake pedal is up) and opens when pedal is pushed away from the switch, (unlike the brake light switch which closes when the pedal is pushed). This means it must be positioned and adjusted correctly for cruise to work.

brake pedal switch the long part of the switch should touch brake pedal arm.in which turn off brake lights, when press brake pedal this will cause closed circuit and brake lights will turn on.

Car wont shift out of park, the most common reason for this is the brake light switch may be bad. have someone look at the brake lights as you step on the brake and see if they are working. the shifter release works off the power for the brake lights. if the brake light dont work then first check the fuses , if the fuses are good then you will need to check for power at the switch which is located at the top of brake pedal bracket, there will be wires connected to switch, the way it works is one wire will have power at all times and then when the brake pedal is pushed the power will flow through the switch to brake lights and also to shifter release, now if the power is not going through switch then replace the switch. another setup used is the tps sensor, im not sure but this year may use this setup, a bad throtle postion sensor will cause this problem as it thinks the gas pedal is pushed. this is a safety thing if the tps is out of range it will not allow the shifter to be moved, this would need to be checked with a scan tool to check the readings.

Hi,

When you say you checked the fuse, was this just a visual check....or did you try replacing the fuse the a new one? Sometimes a visual check doesn't show minute breaks in the fuse wire, which gives a false appearance that the fuse is fine.

When the fuse is ok, this problem normally relates to the brake switch (mounted to the brake pedal). When this switch is replaced, you should always use a multimeter and check the switch is operating correctly when touching the brake pedal.

If the switch is ok, then suspect a faulty relay (if applicable to the Dakota).


Cheers,

there is a brake light switch on your brake pedal it seems very well that it is stuck on look under dash at brake pedal arm you will see a switch with wires to it push pedal down and see if switch releses if not you need a new one

Most likely this is due to the brake pedal sensor. It is mounted on the brake pedal arm, under the dashboard. The sensor can be adjusted. Loosen the locknut, turn the adjustment bolt, then re-tighten the locknut. Adjust it so it opens when the brake is released and closes when the brake is applied.

check for loose parts of coluume and ignition switch for adjustment

check the brake switch. It sits above your brake pedal. Just follow the brake pedal arm up and you can't miss it.
