There should be a flasher plugged into your fuse box of attached to two wires under your dash. REplace that and see if it is fixed.

there is a flasher under the dash put your 4 ways on and listen for the tick noise find the flasher unit under dash area driver side there is two one for the 4 ways and 1 for turn signals now that you have found them turn on working signal touch the flasher unit you will feel it pulse and hear the noise when you have the one pulseing on working signal this will need replacing can also be in fuse area have a good day

there is not a flasher unit that controls each turn signal seperately...if the right side turn signals still function...then the left side has to have a front or rear bulb that is bad...there is a seperate flasher for the turn signals...and the 4-way flasher...both are located on the drivers side under the dash above the fuse-block...

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

if turn signal does not work, check the bulbs and the flasher. The flasher should be located under the dash near the steering column, but it's not necessary to take the steering wheel off unless the turn signal switch itself is bad.

If the lights only come on but dont flash, activate your emergency flasher with the turn signal off. Take a walk around the car and see that all 4 bulbs light up. If not replace the faulty bulb before looking to replace the turn signal flasher. The flasher unit is located under the dash on the drivers side of the vehicle. You will have to remove the panel under the dash to get at it.

Try replacing the Flasher Relay. It has 2 relays, one for the turn signals and one for the hazard lights. The one for the turn signals is located Front seating area, driver side, under dash, behind instrument panel, mounted on passenger side of steering column.
The hazard flasher is located Front seating area, driver side, under dash, above kick panel, mounted in top of convenience panel.
Replace the Turn signal flasher.

normally under driver side of dash, usually between driver door and steering wheel area

look behind dash panel under steering wheel,mounted to dash brace. if 4-ways work,flasher will 'click'.
