why doesn't my rear brake lights work on my 1993 ford mustang lx work?

check fuse, bulbs, and if not either of those it's probably a bad brake light switch that is on top of your brake pedal.

If you've already checked the bulbs, I'd say it's the switch on yer brake pedal. Most mechanics will only charge you about 25-30 bucks to fix it. Or you can order the part yerself and pop it in.

What you're asking for is "Limewire for Auto Repair".......Sorry, it doesn't exist........ AutoZone has repair procedures for various makes at their website. That's probably as good as you're going to find, without risking copyright infringement.

Bulbs?

Fuses?

did you check the bulbs and also the fuse also make sure you ahve the correct bulb number in the socket and make sure the socket are tightly seated

it could be a fuse or brakelight on the brakepedal look at the wires on the elec connector at the brakelight swicth one could be broke

YOU MIGHT WANT TO TRY CHANGING THE LIGHT BULB. IF THAT DOESN'T WORK, IT MIGHT BE AN ELECTRICAL PROBLEM.
