brake lights don't work at all.

they stopped working last night. all the other lights work (hazards, headlamps, parking lamps, turn signals). i checked all the fuses, none were blown. there was one wire that was previously repaired because i kept hitting it when i pushed the e-brake. it's a green wire with a violet or red tracer. looks more like violet. other than that i couldn't find anything else. the only thing i can think of is the brake light switch, but after going to 6 places i couldn't find one. when the hazards are on and then press the brake, they keep blinking instead of stopping. also, not sure if this is related, but when i have the key in the ignition and have the door open, the buzzer does not sound. just an observation.

get a manual with wiring diagrams and a multimeter and begin checking for power

You dont have a trailer harness in the back do you?

I do, and i lost my left rear light and was doing the same thing. I disconnected where the trailer harness plugged into the factory harness in the back and that took care of the problem. Something to check

no i don't have a trailer harness. i have a haynes manual but the wire colors don't match up. does anyone know what color wire runs from the stop/hazard fuse? and concerning the stop light switch: one side is supposed to be hot at all times right? the only time it was hot was when the ignition was on, and still no lights.

afaik, one side will always be hot on most of the fuses (which would include your hazard/brake lights). Your brakes will be getting juice regardless of what stat the ignition is in....just a fyi.

here's the wiring diagram: http://www.autozone.com/az/cds/en_us...rInfoPages.htm

Click on figure 31 and 32



You can check the brake light switch with an ohm meter. If you need a switch, quadratec has one. http://www.quadratec.com/products/55217_05.htm

thank you for the help guys!! thanks for the schematics, jeepsurf! they were much better and more informative. in fact it brought something to my attention. whenever it rains, my soft top leaks water down on the steering column right where the steering wheel and column meet. according to haynes, there's a key buzzer switch there under the turn signal switch. the buzzer does not sound when i have the door open and key in the ignition. after the stoplight/hazard fuse it splits into two circuits: one goes to the brake lamps switch, and the other goes to the buzzer module. my theory is that the water shorted out the key buzzer switch in the column, thus shutting down power to the brake lights. but if this is so, why didn't the fuse blow? does this sound like the cause?

If you had rust in there or some corrosion, It would cause an open circuit. Thus not a short so no blown fuse. 1st thing I'd test would be the brake switch. Pull both wires off and touch them together. If your brake lights illuminate, You've got a bad brake switch. If not, Then you can use the schematic to trace out the prob. I'd try that before tearing into your column.
However, If you have to do that here's a write up ----> http://www.epiccomputer.com/dale/jee...tilt/tilt.html.
Hope this helps.

well, problem solved! after i replaced the key buzzer switch and cursed for an hour that it didn't solve the problem, i checked the fuse again and this time it was blown. why i have no idea. so i replaced it and now they work fine. btw, don't use those stupid 2 prong fuse testers that come in the fuse assortments. they don't work good at all.

thanks alot, guys!
