Rear turn signals not working.
3 Answers
If this has sequential turn signals in the rear then the module could be bad but you need to check for power and grounds to the sequential module. Now if it doesn’t have sequential signals then most likely the turn signal switch has went bad but you should check the 4way switch to make sure it is all the way off, maybe cycle it a few times.
Check the flasher relay. Usually located under the dash.
