Erratic blinker behavior

I feel silly posting a question about my turn signal circuit on the forum, but this issue is starting to get on my nerves!

So whats happening is my turn signals are occasionally going into "hyper" mode which typically signals a drop in current through the turn signal circuits associated with a burned out bulb. However there is no rhyme or reason to when it happens. I will be sitting in traffic, waiting to turn (doesn't matter right or left) when suddenly the blinker will start going at double speed for an indeterminate amount of time. Sometimes a couple seconds, sometimes a minute or so. Sometimes it will continue for the next few turns and then return to normal.

All of my lights are working, even when the flashers are going quickly. I've been able to pull over when it's acting up and do a walk around to make sure.

As far as equipment goes I have replaced all of the lights. My tail lights are IPCW LEDs which come with the proper resistors to register the correct voltage. I've had these tail lights for over a year now and the hyper flash problem has been from the last couple months. I did the marker light blinker modification so that my fender lights blink with the turn signals. Again, that was probably the first mod I did to my Jeep forever ago and I don't think that is the culprit. More recently I replaced the blinkers and fender lights to clear lenses with amber bulbs. However I was having the hyper flashing with the OEM lights, (part of my justification for swapping the lights was to hopefully eliminate this stupid hyper blink).

Could this possibly be a blinker relay starting to go to hell? Is there any way to check that? I'm really confused by the way the blinking will change speeds and I can only imagine what the people behind me think is going on.

blink...blink...blink...blinkblinkblinkblinkblink. ..blink...blink...blink...

Any help would be greatly appreciated.

Had this same problem, although mine was a little but easier to fix than it seems yours will be. For me the bulb terminals on the front facing markers were filled with dust and dirt which wasn't allowing a good connection, making the jeep thing their was no bulb at some random times. Cleaned those out and it hasn't happened since! Hope yours is as easy to fix as mine was.

I can't remember if I put any dielectric grease on the connectors when I installed the lights but it certainly can't hurt to double check. I hope it's that easy to fix as well. *fingers crossed*

Looking around some more, it could be that your multifunction switch is going out, blinker problems are typically a first indicator of this
