Turn signal driving me nuts

My wife was driving our Jeep home today and the blinker started flashing very quickly, bulb right? Not so fast, changed bulb, cleaned up plate in back where bolts go through, put back together, same problem. Changed whole assembly, didn't help. If the headlights are on it blinks normally for a few seconds the same problem. then the light on dash blinks quickly, but bulb doesn't blink outside. Any ideas?

possibly turn signal relay.

Or, did the dash get wet? I know my turn signals act up after a rain if the top is off. After a few days to dry, it's back to normal.

Mine kinda had this problem. I had brush guards on at that time. The factory screws used to ground the tail lights were rusty and I guess slipping. I replaced them with stainless..self tapping (was a little bigger than stock). Solve my problem.

Cool Funny story...

my left turn signal started blinking and I had to stop and pull the breaker to shut it off...even with the keys out of the ignition. Went to Auto Zone and they gave me two flashers called for...told me to return the one I didn't need. Pulled the instrument cluster trying to track down the "clicking" noise in an efffort to locate said flasher. Turns out...there WASN'T one! It was a printed circuit. I made certain all bulbs were well-connected and circuit was undamaged. Re-assembled and has worked fine ever since. Returned BOTH flashers. Hope your fis is this simple...I was shocked.

Pull the steering wheel cowl and unplug the harness to the turn signal lever then plug it back in. May sound silly but this happened twice and it worked.
