No it is not controlled by the BCM the issue is most likely caused by the turn signal switch itself, a bad internal connection, very common on GM cars and trucks.

Hello, Well there is not much more it could be unless you have a shorted wire or a burned fuse. I would normally think that the turn signal canceler was bad but the 3rd brake light will still work if that is bad so I would check all fuses and for bare or shorted wires.

Running lights work but no blinkers or brake lights. Changed fuses and bulbs no luck


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.

My 94 buick regals turn signals and brake lights dont work the head lights and tail lights do work we replace the bulbs flasher relay and fuses what could it be


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

95' Buick regal, 3rd brake light works, tail lights work, turn signals work, stoplight switch seems to work ie 3rd brake light working, fuse is ok, changed bulbs, but no rear brake lights.


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.

2000 Nissan Maxima. Headlights work but tail lights won't come on. How do you fix the wiring of this?I have changed the bulbs and nothing. The brake, reverse, and turn signal lights work, so the bulbs...


tail lights work on a different filament than the rest of the lights you mentioned, it is possible both bulbs are burned out for that filament. if not, check the fuses as the tail light circuit in some cars is on a seperate fuse. the remaining possibility could be bad socket contacts.

Rear Brake Lights not working, 3rd light is working


check the fuse for the stoplights. Even though the 3rd one is working it should be on a different fuse. With both of them not working even after you changed the bulb it would seem to lead to a fuse.

Brake lights dont work untill i turn the lights on, then stay on


Hi, are the tail lights and the brake lights in the same light unit?
If so, there is a possibility the bulbs are in the wrong way. If it is a stop/tail bulb then there are two locating pegs on the side of the metal part. If you look, one is higher than the other which has to locate into the correct slot in the holder.

Another possibility is the bulb is wrong, there are double and single contacts. Check the contact on the base of the bulb is the same as the contacts in the holder.
