2014-2017: DL8, DL3, Towing Mirror Upgrade – Mirrors Explained

[TeamsterGene]

Sorry, but you may have noticed I am a novice on this stuff.  Does the harness you build have one plug on each end, and where do the ends connect.  My body man that switched the mirrors actually got some harnesses from GM, but they did not have plugs on the end.  He didn’t want to tackle that.
How do I make the purchase?
 

Rest assured, novice or not, that with Phil’s harnesses and by watching his how to videos you’ll be able to accomplish this as I did. I have very little ‘mechanical’ ability and the wiring especially frightens me although I tore into my doors 3X to upgrade my mirrors to exactly what I wanted with Phil’s assistance. You’ll find a great deal of praisegamboa from the members here on various topics, primarily the mirror upgrade.

Hello Phil,

I'm new to this forum. But I wanna start out by saying thanks to all the work and knowledge your providing here.

Looking to purchase DL3 power folding mirrors for a 2015 sierra SLE 2500 w/duramelt.

Currently installed are the dl8 tow mirrors non power folding. So watching your youtube channel and reading this thread I took the door harness off to determine if I'm missing any pins. I noticed we're missing the #9 and #11 pin.

The option I'm looking for to work is the power fold, don't really care for the running lights working right away. at least till I'm ready to tackle installing of the RZY jumper harness.

How do we know if the pin is there for the power fold mirrors. will have to swap out the power folding switch...

Thank You!

RZY harness takes care of pins 9, 11, and 41 at the door jamb. When you say DL3 Mirrors, do you mean Tow Mirrors? If so, power fold tow mirrors are DQS Mirrors, non-power fold are DPN. Just want to make sure of the mirror type you’re looking to upgrade to.

 

Also, since you’re a 2015 - 2500, can you tell me if you have the AVF RPO in you Glove Box?

 

Power fold circuits are on pin 4 and 18 on the 18-Pin Mirror Connector. These are usually present and doesn’t require anything extra except for the switch needed to fold/unfold

You need to look at the very first page of this thread and do some reading sir. From there you will need to provide more info about your truck along with current mirrors and the ones you actually want to upgrade too. You should really only need the mirrors of your choice along with a custom PnP harness from@pgamboa

Thansk for reaching out and welcome to the forum. Like@chrispassas21 says, please read the very first post in its entirety.

You’ll need to decide what type of mirrors you want. GM or Aftermarket, Power Fold or Non-Power Fold. These are the two cost differentiating factors.

You’ll need to you Harnesses. I make this Plug and Play, so let me know what direction you want to go once you’ve decided. You can also PM me for more info if you have questions after reading the first post. There is a lot to consume and can be confusing, so PM if you have any questions.

Thanks,

Phil

Thought I would give an update on my continuing upgrade saga. 

 

Story so far... 2017 2500 LTZ Midnight. Came with DL3 mirrors. Dealer agreed to remove and install DQS mirrors. DPN were installed because ADI claims a DQS install cannot be done.

 

Update:

Heard from the dealer today. Service manager has been working hard to resolve this situation. They have the TSB I sent them which covers 2015 and 2016 models. They had several conversations with ADI and "Partech" about the mirrors. While they now admit the mirrors CAN be ordered, they claim there is no way to install them. While they acknowledge the TSB, they claim it does not apply to "new" vehicles. (Again, if anyone can show me documentation that covers 2017 trucks, it would be greatly appreciated).

 

I'm tired of arguing this. They claim the mirrors are $700 each (although I see them on many authorized parts sites for around $500 each). I proposed they get me those mirrors in exchange for the DPNs they already installed. They can get me one with a GM credit based on other problems I have had. They are going to the sales dept to see if they will cover the cost of the second mirror.  I don't know how much luck I will have getting them to honor they DQS paperwork they provided. I might consider small claims court if necessary.

 

I told them I would install the DQS myself. I'm really hoping the process is as easy as people here say it is. Maybe I can get them to not reassemble the door panel when they remove the old mirrors. I would still rather find a dealer willing to do it.

 

The whole process (along with some other, unrelated issues on my truck) has left such a bad taste. I totally regret this truck purchase and am counting the days until I sell it. Chevy really needs to get their act together. This mirror upgrade should be a simple thing.

 

If anyone knows of someone in the New York area who can do this install, please contact me. If you can recommend a better after-market mirror, I'm open to that as well. It shouldn't be damn frustrating to do a simple thing.

 

Edited to add: There's also another factor. What if they are right? I could go through all this and the mirrors will not work! Can anyone confirm they have upgraded to DQS on a 2017 truck?

Ordered mine from this website a week ago. 1 day after I ordered it, it showed up at my door. Good experience from what I’ve dealt with them. https://www.generalmotorspartsonline.com good luck!

I had the chrome caps painted the color of the truck. My question and I searched some videos but still not that clear as to getting the bleach ones off. Anyone tried changing the caps on the A1 tow mirrors thanks.
