    I have a 2015 t680, and the right side led fender blinker has quit working. When all the lights are switched off, it works. When you switch the lights on, the marker light works, but does not blink. All the rest of the right side blinkers work, and the indicator on the dash blinks about twice as fast as usual. Has anyone else had this problem? What was the fix?
    The plug was still connected, and gave no appearance of broken or loose wires.

    Have you tried shutting the truck off and restarting it?

    Yessir. It didn't make any difference. I noticed it doing this a couple of months ago and wasn't sure what was causing it. It just happened randomly, and I thought it was an issue with the trailer. It would start blinking normally, then after 30 seconds or so, it would start blinking fast.

    When mine starts blinking fast on the dash there is nothing blinking on the outside. If I turn the turn signal off and then right back on, it works normally.
    And it only seems to happen turning left.

    I suppose I'll just have to get either our company mechanic or the local KW dealer to look at it.
