Brake lights on my wrangler won't work

Either lose wiring or 292nd fuse box under the hood

Check the brake control switch situated just above the break pedal arm under the dashboard. Could be a wire loose or unplugged or the switch itself could be faulty

Check your Fuse holder for the brake light fuse. Its likely it[the fuse] blew.

Its usually a 15AMP fuse, as for the literal location of the fuse box check any of the following places: Under your glove compartment(by the footwell) or the drivers side footwell... .or under the hood.

This is a good fuse:

I had the same issue. Check fuse number nine.

Have yoiu changed/checled the lightbulbs? (In other words,do your turn signal lights work? If the front turn signal lights work, but the rear don't, then turn on your four (4) way flashers. If the rear lights still don't work, then all the bulbs are bad. It is rare for all the bulbs to be burnt out at the same time, but it does happen.

If the turn signal/four way flasher lights work, then you probably have a bad brake light switch. However, first check your owner's manual to make certain there is not a separate fuse for these lights. If there is, then swap the fuse for the brake lights for another fuse (or relay) of the same size/amperage. (Facing the hood, the power relay box is located on the right side (usually) under the hood.)

The fuse box is located under the dash, on the driver's side of the car. Usually there is a plastic cover that has to be removed to access the underside of the dash, and then there is a plastic cover that has to be removed to access the fuse box. If you don't have an owner's manual, nprmally the fuses and power relays are normally marked on the plastic covers your remove ot access the fuses and power relays.

If the fuses/relays are good, then you have a bad brake light switch. This is located on a bracket just above the brake pedal. When you push the pedal down, the switch makes contact. Disconnect the plug to the switch, and jump across the plug contacts (not the switch) with a small piece of wire, or if a piece of insulated wire is unavailable, you can use a paperclip, you won't get schocked, just make certain that the paperclip does not come in contact with a ground while you have it plugged in to the plug for the brake light switch.

If the lights stil dont work, check for power to the plug for the brake light switch. If you have power to the plug, the turn signals and four-way flashers work, then my guess would be that you have a broken power wire (probably iside the steering column, or a bad turn signal switch. If the brake lights work whe nyou jump out the brake light switch, then the brake light switch is defective.

It does sound like brake light switch, some have separate circuits for 3rd brake light. One question for ya... do you have trailer hitch/wiring on the car. Sometimes trailer wiring will short out and give same symptoms.

check brake light switch on back top of brake pedal. it may not be getting any power or it may be out of adjustment or bad. the fuses are in under hood fuse box.

cheak the fuse

Check the Inside Fuse Box with a Flashlight for Blown Fuses. Then Check the Fuse Relay Box Under the Hood. Check the Fuses in that one to, If the Fuses are all good, Locate the Illumination, and Brake. Replace these Relays. That should get them back on, Let me know! Please Rate my Response, I need all the Help That I can Get! Thanks!

if the 3ed brake light works , rapidly move hazard switch back & forth & recheck, if they now work change turn signal switch , they are being canceled by switch
