Bad ground Bad switch in steering column
Check the bulbs Check the flasher
You have to start by checking the bulbs or the flasher I think it may be the flasher.>>>>>>>>>>>>>
If neither signal light works, the flasher may very likely be the problem. The hazard lights and the signal lights work off different flashers.
How bout the turn signal indicator switch located in the steering column.
First check the fuse, then the bulbs, then the flasher relay, then the signal switch.
First check the fuse if none of the lights even come on. If the lights come on but do not flash then the flasher relay is defective and needs replacing. If the fuse, light bulbs, and flasher relay are good then the turn signal switch may be the problem.
Could be anything from a bad flasher, bulbs are out or the turn signal bulbs could have dirty contacts.
Change the turn signal flasher relay.
Check the fuse, check the bulbs, check the flasher relay, in that order.
You have to replace front and rear bulbs.
Replace the signal flasher relay.
Check your bulbs and your flasher.
