If fuses are good, I would check the flasher. Located under driverside dash by the steering column.

Why my emergency flashers work and my signal lights don't


the hazard lights use a different flasher(relay)then the signal lights.you don`t say if the signals work on one side or not,you should check the fuses for the signal lights in the fuse panel under the dash on the drivers side.if you put the hazards on and find the flasher then you will know what the signal flasher will look like,it is on the fuse panel and replace they should work.

1990 buick lesabre turn signals don't work,hazard flashers work, bulbs are ok, running lights & brake lights work, just installed a new turn signal assembly, thought that would fix the problem, it did...


the turn signal flasher is a small canister-shaped or rectangular unit located under the dash, either in a clip adjacent to the steering column or in the convenience center which is located located under the right side of the dashboard and houses relays and other components. The fuse.faulty flasher unit a broken switch or a loose or open wire. We have eliminated the switch, I would check all fuses inside and out, you can replace the flasher with the hazard flasher as if I remember correctly they are the same shape and size, then it is just a matter with a tester light running it from the column to the sockets and finding the break. Hope this helps Tim

My turn signals don't flash


make sure all the bulbs are working. If not check the fuse but i doubt its a fuse cause none of the lights would be on but check the flasher. Flasher Location

It is located under the dash board on the drivers side. You will need a flash light, zip cord for re-installation, a long non metallic rod 1/4" dia and a wire hanger. Bend hanger straight and make a little hook on end. Remove turn signal fuse located at fuse box under driver side dash. Lay on floor with flashlight on drivers side. Look above fuse box it is located above it about 10" it is round and silver. Use rod to push off clamp. Now use hanger to retrieve flasher unclasp and install new flasher. Reinstall flasher and clip under dash with zip cord for access later. Replace fuse. If you need further assistance please let me know. Thanks, midwest-tek

Can't find flasher on 1990 buick lesabre


A friend of mine restores cars and he said:

There are two different flashers.
1. The hazard lights should be found on the steering column.
2. The turn signal flashers should be found under the steering column to the left.

I think that your flasher is bad I believe that the 4-ways flasher is a seperate flasher unit it should be in the fuse box and look like the 4-way flasher , to find the flasher turn on the 4-ways and you can feel it or hear it flashing and lok for the flasher for the turn signals

No turn signals


Have you tried replacing the flasher? They're typically round, and with the fuses under/in the dash. They probably cost 10-15 bucks, usually available at your local autoparts store.

Signal light problem


If the signal lights don't work on either side, front and back, check the flasher, usually located on the fuse block. If this isn't it, let me know, we can continue from that point.
