I would check the wire leads to the light inside the truck. The trunk seals are prone to leaking and cause the exposed wires and leads to rust out. If they are dirty or rusted up, pull out one wire connector at a time from the wire harness plug going into the light. Take a fine grit sandpaper and clean it up. If the break off or are brittle, go to your local Radio Shack and pick up some new ones for about a buck. Cut the old ones off the wire and crimp the new ones on with a pair of needle nose pliers... Easy cheap fix...

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 signals lights won't work on my 1991 Buick Regal. I changed the fuse and thats not the problem. I need to know where the flashers are on a 1991 Buick Regal; 4 doors, 3.8.


The flashers and the signal lights are two entirely different items.

If your blinkers are not working, change the bulb(s), if you turn on the flashers and they don't work then the flasher module needs to be changed which is usually found on the fuse box next to your left foot under the dash.

This will usually either look like a square block or a cylindrical plastic tube. If you turn on the flashers and go down there and don't here it ticking or feel it ticking with your finger on the plastic housing, chances are it is shot, just pull it out go to your local auto store and get another, plug it in and you're done.

Turn signal comes on,but doesn't blink;all 4 hazards work.


Check near the fuse box and the left side under the dash. There are two flasers in a car, one for the hazards and one for the turn signals. You are on the right track for if the hazards are working the bulbs and wiring to the bulbs are eliminated. Once you replace the flasher your problem should be fixed. When checking for the flasher remember they sometimes are clipped or taped up, so feel around as well as looking.
