Turn signal flasher
It could be the turn signal bulbs, some vehicles use separate bulbs for the hazard and turn signals. It could also be a bad switch or wires for the turn signals.
I have found that moisture can cause that problem you may also want to check your fuse and bulbs if you see moisture try to get it as dry as possible
Change front light bulbs
Could be the bulbs or the fuses or the flashers or the signal switch assembly
Check fuse,bulbs, flasher
There are a number of reasons that your signals might not be working. First off, I would check your fuses to make sure none of them are blown; next, check your bulbs. If those are all okay it might be your turn signal relay--in many car models these are located around the fuse panel somewhere, although they may not be immediately visible--also check to see if your hazard lights are working--if they are, and your fuses and bulbs aren't burnt it's probably your signal relay (note: there is one for the hazards and one for the turn signals) If your hazards and your turn signals are not working you may have a more in depth electrical problem, or both relays could be blown--however unlikely. One of the last things I would look at is the actual switch in the driving column that turns on your signals.
The year, make and model would help but, check the fuses, the bulbs, the flasher relays and last but not least, the switch.
Check the fuses and the bulbs.
Faulty light bulbs, damaged engine.
have you tried replacing the flasher u need to replace the flasher can for the turn signals there are 2 one for hazards and one for turn signals usually found in the fuse box, and cost about 3 bucks
Check fuse, bulbs, and flasher relay.
Turn signals just quit working- have replaced flasher- checked all bulbs and fuses, checked all obvious wires, cleaned grounds, replaced the turn signal switch (that was an adventure). At a loss- any help out there? Hazards work fine- all other lights work fine- turn signals dead
