I have an 02 TJ at first the signals they would click slow sometimes, and really fast, now nothing at all. I checked the fuse and it's ok. Could it be the turn signal switch? If so how do I replace it, is it the whole assembly on the column?
Could be the flasher...maybe the switch...bulbs...wiring...
Lots of stuff...rule out the easy/cheap stuff first before going out and replacing the switch which is approx $75 for the switch alone + labor if you aren't comfortable with swapping it out.
IMO...and this is just a guess with no reasoning to back it up...if it were me, I'd be replacing the flasher after checking the bulbs...and then if that doesn't work, I'd start looking into the wiring and the switch.
