Question about 1992 Buick LeSabre

2 Answers

Taillights, bilnkers, brakelights, nothing back there works

I replaced the battery in my buick a couple of weeks ago and now all of the rear lights won't turn on. Every once in a while, they'll turn on for about a minute and then off again. The caution lights don't turn on, the blinker doesn't turn on, and the brake lights don't work. I've checked the fuses and everything seems to be ok there. Both filaments in all of the lights seem to work. What's the deal here guys?

Check the cables going off of your battery. Sometimes there is a smaller second wire attached to one of the posts. If this isnt attached it can cut power to your fuse box and that will stop many odd things from working right.

Rear tail lights wont shut off no matter what I do. What could problem be and how do I fix it

If your brake lights are on then you will need to replace the brake light switch. You can unplug the brakelight switch or pull the brake light fuse to save your battery charge.

If it is your taillights then the light switch is bad.

I have a 1989 Buick Park avenue. A month ago all of the back lights stopped working. Tail lights, brake lights, reverse lights.

Check your fuses underneath the drivers side steering wheel. Flip the plastic cover over and there will be a diagram showing the fuse that controls the taillights/stoplamp. Pull the fuse out and replace it with the same number fuse and your taillights and brake lights will work again. If the fuses are ok, pull each taillight bulb out and replace it with a new bulb. Sometimes when one light bulb fails, all of them will fail.

Brake lights not working

First check fuse. If good go right to brakelight switch on top of brake pedal under dash. Check for power into switch pedal up. If you have power in, press pedal down you should now have power out. If not you need brakelight switch. If you do have power out you have corroded or broken wire from switch towards taillights. Usually back by rear wheels. Need to trace wire to where there is a problem.

No brakelights or taillights.

How did you connect the test light. Clip to frame or clip to one terminal and pointer to other terminal. If you hooked the clip to frame and the pointer to a terminal and it lit, it means that you have power there but not necessarily ground, because your test light provided the ground. What I would do is first of all not use a test light but use a multimeter instead, you can get relatively cheap one (10-30 dollars). The problem is that a test light only indicates that voltage is available not how much voltage is available, a couple of volts will light the bulb in the test light (you want to see battery volts). It's hard to tell the difference between a half lit bulb or a full lit bulb depending on the light from the sun/garage. Use a multimeter and check the clips on both sides of the car. Also check all fuses whether they indicate lights or not. If you put one lead of the multimeter to frame and the other to a terminal and have battery volts the positive side of the circuit is good. Put the other multimeter lead on the other terminal if you don't have battery volts, you have an open ground. When checking volts make sure the brake pedal is depressed. Good luck

Rear brake lights stay on

Hi, It is probably the switch, located at the pedal, a new one is inexpensive and easy to replace. The shorted switch will run the battery down. Good Luck to you, this should Fixya!

No brakelights or taillights

Yop may have a very common problem unique to that year car.
I have two definite fixes for you:
Open the trunk. Look at the wiring harness that is hooked onto the driver side arm that holds the trunk lid to the body. Untape the wiring harness from the edge of the trunk lid back towards the driver rear seat. You are most likely going to find a broken wire or two, prob a green with a red tracer. The repeated action of lifting/closing the trunklid seems to break the brake/tail power wires. If the wiring harness is perfect, no breaks, AND you have a rear spoiler, remove the trunk interior trim that faces the driver side 1/4 panel. Hidden behind a brace will be a small box. This is the brake lamp sensor. If it has failed, you may need to replace this box. Either fix should resolve your issue.
