    DRL only Flicker when engine running- HELP

    First off How do you know if GEN 2 and if 2016.5 model year?
    I have 2016 Cruze LS - it has a LED strip in the headlight assembly.
    When key on - steady lights.
    Car running- the strips on both sides flicker not always and not constant, just on of fast every few seconds.

    This car has 32,000 miles on it runs, drives great.
    It was in an accident left front, and bumper, grill, left. fender and headlight replaced.

    Headlights HI and Low and turn signals are fine...

    Any thoughts?
    Thanks in advance...

    There's no such thing as a 2016.5
    A Gen1 and a Gen2 2016 will both have a "G" in the 10th digit denoting 2016 model year.

    you can tell a Gen2 by the 4th digit in the VIN. It's a "B" on Gen2 and a "P" on gen1


    Was the headlamp assembly replaced with a GM part or an aftermarket replacement. I've seen non original lamp assemblies cause weird issues with a vehicles LED lighting.

    Also just as likely is that you've got some form of damage remaining causing the issue. Such as a poor connection, or a chafed/pinched wire.

    Some people refer to the Gen2 2016 as a 2016.5.

    A quick way to tell is to look at at the Cruze Talk banner. Does the front of the car look more like the blue car (Gen 2) or the red car (Gen 1)?

    Unless aftermarket, I think the Gen1 DRL LEDs were always down around the fog lights. (2011-2014 or so, the headlight it self was the DRL - no LEDs). The Gen 2 DRL LEDs are part of the headlight.

    I know some people do, especially on this forum. Doesn't change the fact that there is no such thing as a 2016.5 Cruze, and perpetuating the misinformation causes confusion.

    If the 4th digit of the VIN on your Cruze is a "B" you've got a Gen2, simple, accurate, doesn't require knowledge of the banner of the site, the ability to see colors, or rely on artwork that may change. 🙂

    Now I see the Blue front end - YES just like that- Confirms Gen 2.. THANKS
    Does anyone have a wiring diagram on these headlights or DRL, anything.
    I think I need to trace the wires from lights back, and or look for a ground.

    Thanks Again guys for the help..

    Ground G101 is attached to inboard side of left frame rail, x110 is the plug at the headlight, x100 is the big 40way connector on frame rail.
    While they have separate wiring and drivers you can see the LEDs share a single power source, which is why one being wonky can affect both. CRUZDRL_1556050938535.jpg

    I'll note that failing LEDs are more likely to flicker under higher voltage - such as when the engine is running. So, while this could be bad connection/vibration, I wouldn't rule out failing LEDs.

    Thanks I know, but both of them?

    Was thinking to day I should check the Alternator to see if working properly and not making them pulse.
    Just have to see how to check that at home with volt meter.

    Thanks everyone....
