Brake lights wont come on

most of them are under the dash on the back side of the brake petal so when you push the petal it hits the switch

maybe brake light switch located near your brake petal needs adjusting...its simply a push button that the brake petal hits as the brake petal is depressed usually u can just pull on them toward you and they'll "self-adjust" after pressing on brake petal...push on brake petal with ur hand and make sure this button is depressed while the pedal is down...

Did they no what they were doing,? Replace the master cylinder for the brakes, End check the lines going to the Brake perporshener that they are not leaking,

if the third brake light works check the turnsignal switch. if none of the brake lights light i would check the fuses and than the brake light switch

the fact that you have lights means your fuse is good-lights all the time means your brake switch (located above the brake petal) is hung up or stuck. You need to get down low enough to see it, under the dash and immediately above the brake petal-as you push the petal with your hand, you will see it attached to the brake linkage-for some reason, it is always 'closed' which causes the lights to stay on, even with the key off (safety reasons, this circuit is always hot). you should be able to 'unstick' it by manipulating it, or you can spray a light coating of wd40 on the assembly to sree it up. Worst case, you will need to replace it, the usually run under $20.

Hi, you may be looking at the cruise control release switch. The stop light switch is behind the pedal as shown below. You're right--this is not an easy fix. After replacing, you need to make up a special tool to adjust it.

1. Disconnect the negative battery cable.
2. Remove the three fasteners from the left side insulator panel.
3. Slide the steering shaft protective cover towards the cowl.
4. Remove the vacuum hose at the cruise control cut OFF switch, if so equipped.
5. Remove the stoplamp switch-to-steering column bracket retaining pin.
6. Unplug the electrical connector.
7. Push the switch arm to the left and towards the cowl to disconnect switch-to-pedal arm. Release the snap clip and remove the switch.

To install:

1. Install the switch and push up until it is seated into the top snap clip.
2. Attach the electrical connectors.
3. Connect the switch to the pedal.
4. Install the switch-to-steering column retaining pin.
5. Connect the vacuum hose if equipped with cruise control.
6. Install the steering shaft protective sleeve.
7. Adjust the stoplamp switch.
8. Install the left sound insulator, connect the negative battery cable and check switch operation.

1. Depress the brake pedal (push down), as far as possible and hold.
2. Using a stiff wire with a hooked end, gently pull the switch set lever forward (toward the front of the vehicle), and listen for an audible click that indicates release of the automatic adjuster.

If no click is heard, release the brake pedal and repeat the above procedure.

1. After release of the automatic adjuster, slowly pull the brake pedal all the way rearward. Listen for the switch to ratchet into the set position (setting the brake light switch). At least three clicks of the ratchet should be heard.
2. Inspect the operation of the brake lights, as follows:
   1. The brake lights should light at maximum brake pedal travel of 1 1 / 4 in. (32mm) and throughout the remainder of the pedal travel.
   2. If the brake lights do not light, repeat the switch adjuster procedure one more time.

the brake light switch may be bad, or the brake pedal is not coming back enough to turn the switch off, look up under the dash where the brake brake is, and you may see if the pedal is depressing the switch properly.

There's a ratchet in the top of the pedal which holds the pedal down when depressed. This ratchet is worn, broken, loose, or it just needs lubricating. I would first try WD-40 on the top of the pedal where it attaches to the frame/chassis.

check the brake switch, you might need a wiring diagram to see exactly how the wiring is, but that is a possibility or it could aslo be the flasher
