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

There are a few possible reasons why your turn signal light is not working while your brake and tail lights are functioning properly:

1. Blown fuse: The turn signal lights are connected to a different fuse than the brake and tail lights. The fuse for the turn signals may have blown and needs to be replaced.
2. Turn signal switch: The turn signal switch, located on the steering column, could be malfunctioning and needs to be replaced.
3. Wiring issue: A wiring issue, such as a broken wire or loose connection, could be preventing power from reaching the turn signal lights.
4. Flasher relay: The flasher relay is responsible for controlling the turn signal lights. A faulty flasher relay could be preventing the turn signals from working.
5. Signal/light module: Some cars have a signal/light module that controls the turn signals, this could be faulty and need to be replaced.

If It is not blinking then it's probably a blown bulb, That's how cars tell you a turn signal is bad. You will only have power to fuse slot when turn signal is on and the blinking part runs through a flasher relay so you could have a bad flasher relay if the bulbs are all good.

These will help.

Thanks.

Did you check for 12V at the bulb base? If not there, you have an open circuit between the flasher and the bulb base. If it is there you have a bad bulb, bad socket, or open ground.

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.

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.

I had the same problem about a month ago myself. I had to replace a fuse which was under the driver side under the dash it cost me $6 to replace. I cant remember the name of the part but call a auto store and explain to them the problem. I think it was called a relay fuse or something! Good luck with that!

Did you check the glove box for fuses? There is a switch in the steering column too that could be the issue.

There's a switch in your steering column. must be replaced
