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.
turn signal switch needs replaced!
Yes if the wire is part of the brake lamp switch
Assuming the signal lights still work, no. But a bad brake light switch or a blown brake light fuse could.
Check the fuse
It needs checked out but both the hazard and brake lights go through the turn signal switch.
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.
If the turn signal is working it's either the brake light switch or the turn signal switch.
Check bulbs, fuse, bad ground, brake light switch.
Bulbs may be burnt out.
in dash lights
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.
Is the light bulb inside burnt out. If so, that would do it.
WEllllllllll as long as you have working brake lights, headlights, and signal lights then yes, yes indeed.
If the fuses and bulbs are okay I would blame the signal switch assembly. They call it a multi-function switch these days.
the turn signal switch is probably bad
blubs blown? Check the turn signal switch.
Bad bulbs? Sockets corroded?
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.
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.
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.
when my 1986 w-250 turn signal switch went out the brake lights quit working.
Short circuit , maybe ????
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.
