Most likely it its the switch. Least likely the fuse.
You can remove the wire connector to test both the switch and the wires. The switch is located above the brake peddle, under the dash. The connector is rectanglular plastic and has a small plastic lever that you need to push down, towards the wires to release the catch. Then pull the connector straight out and off the switch.
I would first suggest you then remove the switch from the mounting bracket and bench test with a Volt/Ohm meter. I suspect the switch is broken internally. The switch can be purchased from most auto supply stores or online at NAPA. COM or ROCKAUTO . COM Switch costs about $12-$16.
If you are sure the switch is OK, then jumper the wires in the connector and see if the lights work. A loose wire in the connector would be the next most likely cause.
If none of the above works, post back in the comments and I will help you further.
Hope this helps.

There is a brake light switch under the dash that the brake peddle makes contact with, there is also a cruise controll cut off switch that contacts the brake peddle also but it will have a vacumn line going to it so be sure to get the right switck

Check switch first, it may just need adjusted sometimes they get kicked around. if not replace. a bad fuse and u would have no lights. if its wiring try to wiggle and see if u can get light to work with pedal down. if so then its the wiring.

Hi, sounds like the switch. If it looks like it's mounted correctly, I would just buy a new one. They are $11 at Autozone. Please let me know if you have more questions.

Thanks for using FixYa.

Break lights dont work but blinkers and other lights do all bulbs are fine but when u push the breaks they dont work


Check under the dash for the switch hooked to the brake pedal assembly, this switch activates your brake lights, push the brake pedal with your hand does the plunger on the switch move? if not see if you can pull it down if you pull it down see if your brake lights are on if yes replace switch. if no, check it for power with a twelve volt test light, if you have power replace the switch. if no power check the fuse for brakes lights see your owners manual for location. Good luck.

Brake lights stay on permanently on 97 ford escort.


the cause is the brake light switch on the backside on top of the brake pedal. it is either out off adjustment or it needs replaced. this switch activates the brake lights when pushing on brake pedal. if it gets out of adjustment or sticks the brake lights will stay on because it does not cut voltage to brake lights. have a good day !!

Brake lights inop on my 88 T-bird


Check your brake light switch. If your car has cruse control, set it at a safe speed and step lightly on the brake pedal and release. If it doesnt disengage then brake light switch is bad.
