Good Evening All,

 

I have a 2014 Silverado 1500 LT Z71. Aftermarket LED headlights and tail lights. Never have had any issues with them but yesterday my running lights just randomly stopped working. My low beams come on but that is it. No side markers up front and no brake lights in the back when I'm in drive or when I remote start the truck. The brakes work when pressed but at night they don't light up until they are pressed.  Turn signals work up front and in the back. Reverse lights work. License plate light works. 

 

I saw a video on youtube of a guy who has a 2016 who had the same issues in the rear and he bypassed it using a butt connector but it wasn't detailed enough for me to do based off the video and quality. Doing that also wouldn't fix the fact my front running lights won't work (the amber blinkers). I could live with the front ambers not lighting up but I'm more concerned with the brake lights not illuminating in drive at night. 

 

I know the running lights are controlled by the BCM. Is there a good chance this has gone bad? Anything I can do to test and see or is this something I need a dealer to test. 

 

Looking for any suggestions. Thanks

So the fuses were blown. Replaced and they blew immediately. Replaced the relay and the fuses again. Fuses blew again. So I’m assuming some sort of short. Could it be the bcm. Any suggestions?

having an issue with my daytime running lights. only one of the 2 on each headlight come on. the bottom one on the passenger side comes on and the top one on the drivers side comes on. But when I hit my lock and unlock button on my key fob all 4 come on. I checked the 2 fuses for the drl's and they are both fine. anybody have any ideas on what to check next?

      Missing thrust bearing? And oil selection

      By Black02Silverado · Posted

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      By revmanii · Posted

      So, lot's of googling and reading, and a trial fit found, that indeed they hit the newer fatter caliper. I did some re-testing today, and found just 3/16" worth of washers was enough for the wheel to spin freely. I added 2 more on each, and again it spun freely. Tested lock to lock with the 4 washers, about 5/16" not quite the 3/8" Im considering, but pretty close. No issues. I've been looking at the BORA .375" spacers and using extended lugnuts to get back lost thread due to the spacer. All the ET lugs I've seen are all .33" reach inside the wheel lug holes. For those that don't like spacers or think they're unsafe, I think it depends on what type of spacers you're using and making sure you get good quality hubcentric ones, and if you're using bolt on ones, regular mainenance, checking the spacer lugs. Not wanting or needing that much spread. Looking for the minimum that will let me run these rims and tires.  it does look to stick out a little, but I really want put these on. and use the stock all-terrains in the winter.
