2000 jeep wrangler, brake lights don't work

trace all the wire sounds like its shorting out on something else


hope this helps

Make sure all bulbs are working. All blinkers, tail lights, brake lights etc. I know you mentioned most of these lights work, however it only takes one light to throw off several others. Trace wiring from each as far as possible to locate a possible break in the wiring (shorts). Also, check the headlights and make sure they are plugged in all the way (even tho they work). Also check all relays. One dirty connection can cause all sorts of problems. Jeeps also are known for their poor wiring and common electrical issues.

sounds like a bad ground

If the bulbs and the fuses are good, check the brake light switch. You might of shorted out the switch when working on the pig tail. Always use a test light or volt meter when installing pig tails. This way you can check for power and ground before hooking a wire up to help prevent shorts. But by what you have said it does sound as if the brake light switch is now bad.

you have a bad ground the brake light are independent of the rest of the lights if the turn signals work and the brake lights don't you have a bad ground blowen fuse or your turn signals are not grounded properly so the turn signal lights may be dim or erritic in nature you can also check the blinker switch for it can be shorted (remember that there are two 1 for the turnsignals & 1 for the fourway flashers

if it is rusty underneath you could have a shorted wire

try refitting bat make sure you have all wires on the connectors, maybe you have blown the bulbs but sounds like a wire somewhaire

Usely dash lights and taillights are on the same fuse, if you don't have dash lights you won't have tailights. If you got dash lights than you could have blown bulbs or maybe a bad headlight switch.

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

I would guess the brake fuse ( this does not use the same fuse as the tail lights/blinkers) or the ground for the brake light bulb.
