We have a buick lesabre 1993. The blinkers quit working. The emergency flashers and all lights work. What could be the problem?

Check the wiring from the signal stalk

check to make sure there is a relay for the hazard lights as normally the switch just connects the 4 flashers and works thought the indicator flasher unit.

sounds like u have bad wires. your car might need to be re-wired

This vehicle should have 2 flasher relays one that operates the emergency flashers and one operating the turn signals.Easiest way to locate these would be to turn the emergency flashers on and listen to where the clicking is coming from usually the flasher are pretty close to each other.Once you find the flasher unit you can swap the flasher unit that is working with the one that is not and if the turn signals work after that you will need to purchase another flasher relay.

Yes all the wiring needs to be complete. Then all the bulbs must be inserted into sockets. left side marker right side front turn back turn reverse lights brake light everything. Then make sure they all work. The problem could even be a bulb thats on the fritz ready to blow but still on and dim little light. if that's all fine then it's probably your flasher. There are 2 flashers one for turn and one for hazards but I think they are the same but still separate. located under dash on either side of the steering wheel. The flasher closest to the door is up in there pretty far it's size is about like a 2 liter cap and it's silver. good luck

It's the same bulbs I believe, so look for the flasher module, the most likely suspect. It should be a round metal or plastic can, pretty accessible under the driver's side dash.

They use a different flasher module for the emergency lights because it's turning on and off more bulbs.

RIGHT BLINKER dead ,front,back, or both..???? If front works, and rear doesn"t (REPLACE REAR BULB).....and vice a versa....If rear and front both don't work replace the FLASHER ..Flasher is located in the FUSE block area.......Listen to the operation of the LEFT or RIGHT flasher operation and you should notice a dirrerence....

The flasher is in with you fuses under your dash. Turn on the blinker and follow the sound. If it wakes any sound you will be able to find it easy, if not I think it is toward the bottom, in the middle of the fuse panel.

Do u mean the hazard flashers work, but not the turn signals? If so, check the turn signal flasher, it should be replaced. If I didn't understand your question, let me know.

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.
