Well got a new tail light from Frankie. Great to deal with.
However, that didn’t help with my hyper flash.
Anyone have any thoughts?

Thanks

Hey everyone. I am still having an issue with Hyper Flash with my 2016 Denali. It comes stock with LEDs. I didn’t change bulbs or anything. Something happened one day about 6 months ago. Just happened. I am hoping someone might be able to help. Dealer here is saying a new board. That is $1000 plus Installation. Help! TIA

Sorry to hear the problem is still present.

 

Could you be more detailed in the term "board"? Do you have a work order quote from them with the actual description of the "board"? Might help some help you.

Actually I don’t. While at the dealer, the mechanic told me this is what he thought was the solution. Also the price for the board was about 1k.
I didn’t want to spend that without knowing for sure.

Thanks

If they can not even provide the actual name of the part, I would personally find another lot who is not just trying to take advantage of you.

 

Ask for details, where is it located, what does it control, is it covered under any warranties, can they show you where it is, so you can take a picture?

Just for the hell of it I would try slicing in a 50w 6 ohm load resistor. This is what you do for trucks that come with incandescent taillights rather than LED. LED take way less power to light. So you need to trick the computer into thinking the led taillights are taking just as much power. Sounds like your computer is misreading the power running through the light. You can buy a 2 pack on Amazon for $20

      Acceptably cheap tires?

      By Atlas · Posted

      Looking at cheap tires for this project '95 Blazer. I'm seeing all sorts of brands I don't recognize. 235/75/15 are the size I'm after.   "Dirt cheap" (<$100/each) Starfire Solarus (AS or AT) Rocky Mountain HT2  Mohave HT Westlake SU318 H/T Laufenn G FIT Entry Level AS (yes, Entry Level is the name of the brand!)   "Somewhat cheap" (<$150/each but >$100) Kumho Solus TA51a Ironman (Les Schwab) Cooper Discoverer RT AT Hankook Kinergy ST (H735) Milestar Patagonia H/T Toyo Extensa AS II   The only one that stands out is the Cooper Discoverer in looks and actual brand recognition for me. $120/each. The buyer for this truck will probably want a visual look of not a completely smooth car/highway tire and this one has slightly blockier tread.   Starfire is supposedly a sub-brand of Cooper. Mohave is a house brand of Discount Tire. The spelling bugs me, I've always known it as Mojave. Kumho, the name, still makes me giggle.   If I was selling it tomorrow, I'd probably go with anything in the Dirt Cheap category. But I may drive this around through the fall and my mind would be ruined knowing I'm rolling around on "Laufenn" or "Entry Level" tires, name alone.   In a world where *most* tires are now offshore-produced, is one low-buck tire much better than another?

      Is your l8t engine bay super dusty?

      By KARNUT · Posted

      Most vehicles have engine covers. The cooling fan’s are below the cover. That probably doesn’t help. I cleaned collector car engines. The rest not so much since the last one protested by missing for a few days drying out.

      Transmission temperature 10speed with 3.0 LZO Duramax

      By Grumpy Bear · Posted

      Point of clarification on this graph. It is the life of the FLUID not the Transmission being graphed. Compare to his comments below the graph. Get it to the top of the graph and you can kill one in an afternoon.
