    Left Side Turn Signal Not Working Correctly

    Ok, I have looked everywhere and cannot find any answers.

    I have a 2014 RAM 3500 with an issue I can’t find.

    The left turn signal/brake light will not work intermittently.

    It is a Laramie, so it has LED factory lights.

    I thought the whole light went out and swapped out the taillight. That didn’t help.

    I read that it may be my third brake light, so I unhooked it and checked that light, then hooked it back up, and all lights began working again for about a day.

    Then it went back to not working, and I’ve checked the fuse and third brake light again but getting plenty of voltage.

    Has anyone had this problem or any suggestions?

    Have you tried dialectic grease in the third brake-like connector?

    It may not have good contact with the pin.

    I don’t recall, is the OEM third brake light LED?

    If not, and you replaced with an LED, that could be giving you trouble.

    Is it getting power to the lamps?

    All these are operated now by a body computer TIPM, and your turn signs are just an input to the body computer. Is your dash indicator coming on?

    Are all lamps front and back not working?
