2018 JK Sahara with factory lighting.



So this issue started up Saturday. Basically when I turn my Jeep on - the passenger (right) blinker goes on and will not turn off. I can move the blinker stalk down - but the driver (left) blinker will NOT activate nor will the right blinker turn off. It's like the right blinker is stuck on - blinks at normal frequency as does the arrow on the dashboard.



No bulbs are out - all lights function with Hazards. If I disconnect a bulb I do get a "bulb out" warning.



As it turns out - when the blinker is on longer than a few minutes I start to get a really annoying chime (think passenger no-seatbelt chime) and a message on the dash that says "Blinker is on". This chime stays on after I turn the car off (blinker is NOT on, just the chime) Like I turned it off - went into the store and came out 30 minutes and it was still chiming. Only way to kill the chime is to disconnect the negative terminal.


I've checked the plugs/connections on the turn signals and everything seems in order. When I disconnect the signal - the blinker will go rapidly and say that it's out - as it's designed to do.


Basically I can't turn my right blinker off. Even with Hazards/Flashers on - the Jeep still recognizes that the blinker is on and i get the warning chime.



Any ideas/tips on how to solve? Doing some searches it seems that most people who have an issue is that their stalk doesn't reset - mine resets but seems to not change the blinker. My stalk does still correctly adjust lights/flogs/interior lights.

if i had to venture a guess I would say it sounds like your Multi Function switch is acting up, either that you have a wire touching some where but seeing as you state that the issue begins after you have activated the turn signal I would start with the stalk

to clarify - as soon as I start the jeep up after disconnecting the battery - the right (passenger) blinker starts up. I could have my stalk down for the left blinker or centered - it just starts blinking the right arrow on the dash and the light.



It only occurred initially after a right hand turn on Saturday.

Sounds like multifunction switch, or flasher. Flasher is easy to swap first.

picked up a new front passenger side signal. gonna try that later today. If it's multifunction - i'll let jeep handle that. Flasher was only $20 and I can't find a multifunction switch that works with the sahara (has auto headlights) and they're a bit more expensive anyway.

changing the front passenger blinker plug didn't change anything.


Also I noticed that there is a small wire harness that isn't plugged into anything. it sits in the steering wheel area under the flat piece between the steering wheel and dash AKA the area that goes up/down.

Changing bulb will have no effect on your problem. That would only affect not coming on, or fast flash.

There are tons of extra wires in a jeep as the harness is common to all and you probably don't have all options.

Flasher, or Multi.

Wait, where is the flasher located on a JK? I thought it was integrated into the instrument cluster? If it is replaceable what type is it and any pictures??

Stand corrected, this is a copy/paste from the factory service manual regarding the directional lights:

The SCM monitors a hard wired multiplex input from the left multi-function switch to determine the status of the turn signal switch, then sends the appropriate electronic turn signal switch status messages to the EMIC over the LIN data bus. Then the EMIC relays an electronic turn signal request message to the TIPM over the CAN data bus. The TIPM responds to these messages by controlling a battery voltage output and the flash rate for either the right or left turn signal lamps through high side drivers on the appropriate right or left turn signal feed circuits. The TIPM also sends the appropriate electronic messages back to the EMIC to control the illumination and flash rate of the right or left turn signal indicators, as well as to control the click rate of an electromechanical relay soldered onto the EMIC electronic circuit board that emulates the sound emitted by a conventional turn signal flasher.

No 'flasher' per se in the JK. So you down to the TIPM or the MultiFunction, or something realy wierd on the CAN bus.

dropped Jeep of Saturday, pick it up Monday (dealer doesn't really do electrical work on weekends).


It was the multifunction switch. Jeep is within 36k/36months so it was at no cost to me.
