Why my turn signals won't work on my 1990 Chrysler new yorker?

If your turn signals aren't working on your 1990 Chrysler New Yorker, it could be due to a blown fuse, a faulty flasher relay, or a bad turn signal switch. Check the fuse box for any blown fuses and replace them if necessary. If the fuses are intact, the flasher relay may need to be replaced, or there could be an issue with the wiring or the turn signal switch itself. A thorough inspection or consulting a mechanic may help pinpoint the exact problem.
