have had lot's of problems with car's?either your turn signal flasher or ( relay ) blew or burned out, your bulbs, are burned out, or u blew a fuse. anything can happen at any time on a car, don't sweat it.check your turn bulbs, your brake bulbs, and your fuses, and test your relay, if u can't, then replace it., or go to a shop that specializes in electrical problems, good luck.

I had that problem with my 1995 silverado. it ended up being the multifunction switch. if you attempt to do it yourself my mighty careful of the air bag.

Probably the flasher unit needs to be replaced. This is an electronic switch which usually mounts underneath the dashboard.

Check bulbs, fuse, bad ground, brake light switch.

Assuming the signal lights still work, no. But a bad brake light switch or a blown brake light fuse could.

User Avatar

either dimmer switch or blown fuse If you are saying that the tail brake lights are working but the third brake light is not....It may be a defective turn signal switch in the steering column.

It needs checked out but both the hazard and brake lights go through the turn signal switch.

If the turn signal is working it's either the brake light switch or the turn signal switch.

Is the light bulb inside burnt out. If so, that would do it.

I would check the running lights for one with a short. I had the same sort of thing with my trailer and I spent way to much time troubleshooting the brake and signal wires. Turns out a running light bulb connector was grounding out on the trailer and messing it all up.

WEllllllllll as long as you have working brake lights, headlights, and signal lights then yes, yes indeed.

User Avatar

If the fuses and bulbs are okay I would blame the signal switch assembly. They call it a multi-function switch these days.

User Avatar

If you have the same bulb for brake and signal, brake light power needs to be interrupted by the signal lights, The brake circuit has to go through the signal light switch so the problem could be there.

User Avatar

possibly the fuse for brake lights......also could be brake light switch----turn signal switch----broken wiring anywhere in the vehicle---relay not working ---any other item specific to your venicle.

when my 1986 w-250 turn signal switch went out the brake lights quit working.

User Avatar

Be sure to keep the rear tail lights, brake lights and signal lights in good working order. To many times you see vehicles with lights missing.

User Avatar

It is the brake light switch. The 3rd light has a different switch. GoodluckJoe you can check under neith the bed for fire where they come together. if ther is fire it is the circuit board where your lights go. if there is no fire then its gonna be in the turn signal switch

It is important to have working brake lights on a vehicle. If the brake lights are not working a person should first check the fuse, bulbs and at last the wiring.
