Brake lights don't work

Your brake switch has gone
bad!

check the dash fuses and open the trunk and inspect the wiring for breaks or other damage.

Sound like a fuse.i would start there first and if still dosent work check the bulbs...hope this helps and if so please rate this post and good luck.

Have had this problem many time's here at my shop, if center brake light come's on which you said it does, fuse and relay are good, the problem is your turn signal switch cause the brake light circuit goes through the switch, the switch is bad even though the turn signal's still work's, good luck, hope this was evrey helpful.

There could be two reasons for this problem of yours.
1. The connections have gone off from the brake pedal switch.
2. The brake pedal switch itself if out.
Open the hood and locate the switch. At the out of the switch connect a wire from the positive of the battery. The brake lights should come on. If the do then the connection is fine and the switch is faulty.
If the lights dont come on then the switch MAY be OK and the wiring faulty (unlikely as from here the wiring has to go to two sides and both could not have gone off simultaneously).
So I feel it is the switch that is at fault and should be changed if confirmed so.
To check the switch connect the same wire to the in of the switch and press the brake pedal. if the lights come on then the switch is OK else not.

Sounds like shift interlock cable. Do you hear clicking noise when pressing brake?

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!

hi, i have sorted this problem on my 99 focus ghia.,check both your tail light bulbs.someone put the wrong bulb in and i had the exact same problems you described.the bulb for brake/tail light has two steel connecters and and all other bulbs have one.i put proper bulb in and the problem disappeared.now lights working perfect and sidelights dont come on now when i brake :)change both brake/tail bulbs on each side.1 euro will fix this problem.hope this helps.

Check the bulb holders, its quite common on these for the bulb holders to burn out, also check the fuses

Probably the brake light switch located near the brake petal.
