95 buick regal brake lights burn out when i turn on signal

That happened in my 1999 Buicke Century. Replaced the bulb 4 times kept burning out all within a week. Finally replaced the blinker socket and no more issues.

The bulb has two filaments; one for brakes and turn signal, the other for tail lights. One filament is probably burned out. Replace the bulb with a new one

it could be a bad seal around the lens, letting moisture in. see if there is condensation inside the lens as well.

Turn signal tail lights and BRAKE LIGHTS NOT WORKING

It can be faulty brake light switch causing the problem or its blown brake light bulb. First check and confirm brake light lamp is working and that's not the case.

For turn signal not working it can be faulty turn signal switch or its issue with wiring:----

These will help.

Thanks.

I'm inclined to believe it is the turn signal switch. When you select left or right, the brake light is removed from that side, and the flasher is connected to the bulb instead, making the brake light on that side flash as the indication that you plan to turn. You have lost everything, but the simple answers check out.

If you have lost signals, brake lights and tail lights, then it is more likely that the ground supplied to the bulbs is not working, since the tail lights share noting in common with the brakes lights and turn signals but ground.

If the tail lights work, the fact that the brake lights and rear turn signals share that switch starts to look meaningful — even more so if the front turn signals also don't work. But the front signals and the rear signals use different circuitry in the switch, so it would be something more mechanical in the switch than electrical in that case.

could be brake light switch but i would be more inclined to think the signal switch is bad, the brake light circuit goes from the pedal to to the turn signal switch then to the taillights

If the third brake light works and the regular ones don't, it is most likely a bad turn signal (multifunction) switch. The switch is able to kill the brakes lights to run the turn signals, and in rare circumstances does this. I've seen it several times. It could also be wiring, especially near the turn signal switch, but it is usually the switch.

Could be a fuse or relay..
Or try replacing the break light switch..
Its located on the break pedal brace just above the break pedal..

Hope this helps !!
rate me good ;o)

Get the Chilton book on this car. Follow the brake lite circuit to ground, make sure it is not corroded. The brake-turn circuit is sort of complicated, so check it out carefully. If the brake lite is controlled by a switch on the master cylinder, check it out.

i had the same problem had to replace the turn signal switch....GM for some reason wired the brake lights through the turn signal switch. to check if this is the case with yours. put some pressure on the turn signal lever as if you were going to turn on your brights and press your brake pedal and see if the lights work at that point that is how i found mine. hope this helps. if indeed they work with pressure on the turn signal lever. the new switch cost me $60 at autozone and that is with the steering wheel radio controls, make sure you get the proper switch should be part# sw771 if you have the radio controls on steering wheel and you will need a steering wheel puller and lock plate compressing tool.
