You know how the new Sierras and Silverados turn off their running lights on the side of the blinker when engaged. Is there a way to keep the light on when the blinker is on? I have a 2016 Sierra Denali. I notice the new Escalades do not turn off those lights any more.

I am going to piggyback on this question, any way to keep the turn signals yellow, rather than the dim white hue that they put now? I like the look of the yellow in the led a lot better when the signal is turned on.

Turn your headlamps or park lamps on. In DRL mode, it cancels out so the signal can be seen over the brightness of the DRL. Every car I've seen with LED DRL cancel the DRL when the flasher it turned on. It's all BCM controlled.

This. The brightness actually is a Federal law (the blinkers cannot be brighter than any lights located within a certain distance of them -- I can't remember the number but it's in the FMCA code).

 

OR:

 

You could always buy a Silverado LTZ (they have a different light setup with 2 rows of LED's and the top one is a switchback).

DOT FMVSS - article 108 covers exterior lighting standards. It has not been updated in about 2 decades. You can google it.

And look for this GMC Sierra Turn Signal DRL Override Harness.

I hope this helps.

Thats all fine and dandy but a local cop pulled me over last week just to 'give me' a friendly warning that my front 'light bulb' was out. I said, what do you mean? And she said, one side was lit up around but the side where the blinker was on was out. I knew what she meant and said I think this is a feature. Having looked at it closely now, it does look really strange at intersections. I did order the harness and will install it ASAP.

      OCI, not when but why?

      I imagine the cold winters up here with repeated short runs in town every day for those that live and work in town and given what I have come to learn on this forum with DI engines having fuel dilution issues, and if they don't change the oil until it says to but keep driving it for a while, I bet all that is just lovely on those finicky lifters.

      AWD conversion to Z71

      By teamjnz · Posted

      I just did some reading and Stabilitrak is more than a what I had originally thought. It is more of a vehicle control system to help the driver in precarious situations. I thought it was only the AWD system. Now I know. So I changed the title for this thread to AWD conversion to Z71

      Sounds like converting will be a bigger endeavor than I was thinking. This truck doesn't have 2Hi like the Suburban did. The Tahoe has 4Hi and 4Lo and a button to turn of traction control.   From what I understand the Stabilitrak uses open diff in the front and rear. When wheel speed is not the same the stabilitrak uses the ABS system to slowdown the spinning wheel(s) to transfer power to the slower non-spinning wheel(s). I thought the transfer case was open too. Being able to transfer power either more to front or rear depending on wheel spin. Maybe I miss understood some information with you saying and power transfer is 50-50. Thanks

      My brother has a 2007 Avalanche with afm 5.3. It`s got 176,000 miles. Runs like a clock. Never been apart. Co worker has a 2010 Tahoe with afm 5.3. 230,000 miles. Never been apart. Runs like a clock. So, even though cyl deac is a weak spot, they can go the distance.   BUT, these engines had the oil changed regularly, AND had 5w30 as spec. I wonder if they would have lasted this far on 0w20? I`ll bet not.

      I certainly could be wrong but I hear of pickups far newer than that 2007 cutoff which may not be going to the wrecker but are having engine work done and be that a reman engine or new engine or trying to repair the existing engine. Some of it would be design issues as per the cylinder deactivation system that GM has and one of those lifters wiping out the cam and the question of oil changes moving the needle or not on that whole mess, or in the case of Ford pickup engines that have the long timing chains and wearing them out and the roller followers and phasers and some of that certainly goes back to oil change intervals. But in those various cases the truck has all sorts of life left in it and so the unfortunate owner and may be original owner or used market owner that is pouring money into repairs so the truck is not seeing the salvage yard yet but damage is happening by infrequent oil changes. A friends son had bought a 2018 I think it is half ton GM and it had some sort of extended or used dealer warranty on it and of course the lifter issue bites and its rattling and so the dealer had to swallow the bill and was at least 7000.00 and I think they only replaced what they felt they had to replace so yeah, I can see that being a ticking time bomb in the not too distant future. Would frequent oil changes cure all these engineering "marvels", probably not but some engine designs have shown that they do much better if the oil is changed a lot more often then if the manufacturer service claims are followed. New trucks cost so much that there is an incentive to keep the existing truck on the road by repairing.
