Try replacing the flasher relay.
turn signals and emerg flashers work off a flasher can. go to any auto store and buy a new one they are cheap and easy to replace
either a bulb or the signal flasher relay located on the fuse panel usually opposite the hazard flasher relay
have you checked your fuses?
Check out the "Related Question" below for lots of information about malfunctioning flashers on Taurus - Sables. It's not as bad as you might think...
Because the hazard/turn signal relay has failed. A defective/intermittent turn signal switch can also cause this symptom.
the most common thing is a faulty multifunction switch.
you might have a bad Flasher relay.
It is your multifunction switch that has gone out. It is located in the steering column. I used my emergency lights and it blew out brake lights, turn signals, and emergency lights. In newer models Chevy did a recall not so for our older models. Mine is a 1995.
There is usually a relay for the flashers and turn signals. It is usually a round metal looking thing in the fuse box. This is usually the norm. I have never worked on this specific vehicle, but they are all simular. Good luck.Brad.
Check the bulbs - they are doubloe filamented with the smaller being for brake/turn signals Check the fuses
More than likely the flasher relay is defective. Replace it.
It can, if you leave the lights or flashers on too long.
