replace the flasher(underneath driver side dash panel)
check light bulbs in both lights
The turn signals are not fused front and/or rear. If the rear are not working you need to check for power and grounds for the lights.
Check the bulbs first but it can also be the flasher.
you need a new bulb in right front.
On many cars one bulb on one side will cause both front and rear turn signals not to work so 1st check bulbs. Hope it fixes.
Your fuse box cover should have a label inside showing which fuse is for which componet. If you don't see it on the fuse box inside the car, try looking at the one under the hood. I don't think it's under there for the turn signals, but the headlight fuses are under there. If the back signals are working, it's probably not the fuse, but burned out bulbs in the front. You can tell if the front bulbs are burned out just by looking at the turn signal indicator on the dash. If one of the bulbs is burned out, it will blink real fast on the dasn indicator. I hope this helps shed a little light on it for you.
Defective flasher relay.
usually one or two bulbs are out
One of your turn signal bulbs is burned out. Either the front or the back.
You need to remove the front grill to get at the front turn signals (and bulbs). A lot of work for what should be much easier.
AnswerReplace the Flasher Relay. did you look at your bulbs
Pull the panel in front of the battery box, it the shape of a triangle, there are fuses and relays in there.
