SOURCE: Blinkers not working
Did you check the bulbs? If one bulb is burned out, the blinkers won't word on that side. You could have one bulb burned out on each side. Start the car, put left signal on. Check front and back lights. Is one light on but not blinking? If that's the case, the light that's not on at all is burned out and has broken the circuit so the good light stays on and won't blink. Check the other side. You also have a 'flasher' , actually 2. One for emergency flashers, one for the turn signals. It could be that the turn signal flasher is shot. You just have to unplug it to remove. It's probably located near the fuses. good luck countrycurt0

Check flasher unit on fuse box (some may use "module", under dash on right side of steering column, usually)

there is a small fuse in your acctual operating stick or indicator arm, if warning lights are working then i would strongly recommend changing this as only the relay/power supply to baord could stop them working. there is also i have been informed a relay under the bonnet which you could try to replace as well.

What you need to change is the flasher. Go to any auto parts store and buy one. Ask them to help u change it.
please mark this as a fixya! thanks

Hi Bill,I think before replacing anything else you should give that hazard switch a good workout.The switch doesn't get get used very often and the contacts get corroded and can upset the indicators.Good Luck.
