Hello all,

New to the forum. I have an issue with my truck. 2015 GMC Sierra 2500 HD. Just put on tow mirrors. Stock mirrors had full options (integrated blinker, heated, power adjust, power fold in, and puddle lights) My tow mirrors have integrated blinkers, heated, power adjust, manual fold in, amber marker light on back and reverse LED. My issue is, my reverse LED's do not work. I have a cargo light button which turns on the cargo light in back but not the reverse assist lights in the mirror. Is there any way to make them work? A trick or anything? Thanks!

When was your truck built?  Should be in the door jamb.  Or if you've got your VIN.

Open your door, unplug your door harness from the frame. Inspect the dash side (side with the male pins). Using your phone, take some pics (or a video) so I can see/count the pins. What you’re looking for, are pins 9 and 11. If they are present, then the upgrade will be much easier than if they’re missing.

 

See pic

To get the lights to work, there will be a need to either modify your door harnesses and add the missing pins for the lights OR swap them out with a custom built set of harnesses from me.

Also, if your mirrors are aftermarket, it would be a good idea to test the lighting circuits on them to see how the amber light and the indicator on the glass light work. Some manufacturers tie these together as a blinker only. Some have them separate.

Thanks pgamboa! Sorry it took so long for the response. It looks like I do have the pins needed. What is the cost of your harnesses, and how can I purchase them? Also come with instructions? Thanks again for your help!

You do have pins 9, 11, and 41 here, So that’s good. You won’t have to worry running any wiring inside the cabin or under the hood.

 

This is what will take care of that. https://harnessdr.com/product/2014-2019-dl3-tow-mirror-upgrade-pnp-harness/

It kind of sux to get it out but not too bad. Basically just follow pgamboa's pic instructions in this post. If you had a little mirror, you could prolly see the pins that way instead of popping out that part inside the truck.

I have a similar issue. Purchased. 15 high country that has tow mirror. Truck was wrecked before so that may be a cause. The driver side mirror functions properly except the reverse lights on side of mirror. The passenger side mirror is a replacement but has no power to it what do ever heat blinker mirror motor power fold none of that works. I took the mirror off and plugged it into the driver side pig tail and the mirror worked, all except the reverse lights. Anyone else had a similar problem or know a fix? I assume the high country came with tow mirrors as it has a factory button for power folding.

Can you share a pic of the glove box RPO codes? When you turn the headlights on, the amber lights come on?

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I find it amusing the OP doesn’t realize this threads heading includes several engines. He should have posted in the off topic section if he wanted a more narrow focus. I really appreciate and find amusing that he actually pointed out one of my many vehicles. The Odyssey. That happens to use 0-20 oil. I love pushing his buttons.

      Missing thrust bearing? And oil selection

      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.

      By Black02Silverado · Posted

      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.
