Question about Buick Century

1 Answer

Hello sir. I have a 95' Buick Regal. Whenever I turn the headlights on the rear brake light fuse blows out and the tail lights stop working. The headlight switch has already been replace with a new one from the dealer. Any suggestions on where to start looking would be helpful. I read one of your solutions that said to check the power leads to the headlight switch and was wondering if you are still able to upload the wiring diagram. Thank you.

Well, yes, look for damaged and grounded running light and brake light wiring, start at the tail light itself, I usually use a circuit breaker in place of the fuse, for diagnostic purposes and then follow along the wiring with an inductive amp meter. the meter will react until you pass the damaged area, at which time you get nothing. It is likely that the issue is not the headlight switch, as two switches do the same thing..

I have no break lights or turn signals


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:----

1995 Buick Regal where is the Tail light fuse hidden at? What is it labeled as?


That info is not in my wiring diagrams. It should be in your owners manual if you still have it.
The fuses should be in the glove box or the box in the engine compartment labeled cluster lamp or dash lamp and Tail or Park.
Keep in mind you are dealing with two different circuits so two different fuses. If both fuses are good, check for power output at the headlight switch.

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.

No tail lights or turn signal,just running lights and flashers


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!
