Brake lights permanently lit on 1994 Ford Fiesta Classic

Even though you identify the dash light as traction control check the brake and clutch pedals for switches. The car makers design the car to not start if it can not tell if your foot is on the brake or clutch.

Some car makers use a control on the Traction system
to interrupt the engine by smothering the air intake or killing the spark in order to reduce rpm so the wheels do not spin. Some even automatically apply the brakes to equalize the wheel spin in the right and left wheels.

If you try the first things first to no effect you may have to remove the wheels to clean the sensors so the trouble warning disappears.

Do you still have the old switch and are you sure that the hitch pin is in place holding the switch in the right position there might have been a nylon bushing on the brake pedal shaft that's missing if you press the pedal while looking at the switch and it partially moves this is the problem that switch is not to move and the rod should press in the switches plunger which activates the lights I'm going to try to find a photo watch for the next post

at the top of the pedal area there is a switch that opens when you put your foot on the brake pedal. what could of happened is the switch may be out of alignment causing the switch to be permanantly on. just adjust it. hope this helps

asking where is it? its located on the brake pedal up near the pedal bracket. when pedal is depressed, the switch completes contact to power to brake lights. If you look at it, the plunger will move out when pedal depresses.

Under the dash below the steering wheel and above the brake pedal there is a switch. When you depress the brake pedal the switch is activated and the brake lights are lit. It sounds like the switch has loosened and needs to be slightly adjusted and retightened. The switch is held in place by a single screw and nut. This is also the adjusting point for the switch. If you push upward on the brake pedal the lights will probably go out. That slight movement will show you what a small adjustment is most likely needed to correct your problem.

The shift interlock system prevents the shifting from PARK unless the brake pedal (2455) is depressed. The shift interlock system consists of a shift lock actuator (3Z719) mounted at the base of the steering column tube (3514). If the ignition switch (11572) is in the RUN position, the shift lock actuator is continually on unless the brake pedal is depressed. The shift lock actuator is the logical culprit. Check to see if it's getting voltage when the brake pedal is depressed. If yes: the unit is either faulty, weak or stuck. I can provide wire numbers and colors if necessary. I may need the engine size and Trans. code found on drivers door sticker. Good luck! Aoogha

Sounds like your brake light switch has gone bad. It is located on your brake pedal and is easy to change and relatively inexpensive. Let me know if you have any more questions. Thanks for rating my response and for using FixYa!

Check behind your brake pedal. I don't remember what the parts were called but the same thing happened to me. When you put your foot on the brake there is a plastic or rubber circle attached to the brake pedal that comes in contact with a switch. It causes the brake lights to come on. When you take your foot off the brake it turns the switch off and the brake light goes off. Over time this rubber or plastic circle gets worn and it is still in contact with the switch so it remains on. When this first happened to me I was able to adjust the switch so that the pad came completely away from the switch when I took my foot off the brake. The second time it happened I had to replace the pad on the pedal. I actually made my own because it looked like it was part of the pedal. I also had to replace the switch another time. The switch cost under $20.00 from a parts store.

no disrespect but....
Check the book and make sure you are using the proper bulbs on all sides. (3957 looks just like 3956 but wont work right)

hi simple one the brake light bulb replace the bulbs brake light filiment has gone on one side droped on to the lights circiut hence press brake light headlights come on and vise versa yates210456
