I popped the puddle light out of the mirror and cut the black wire on both puddle lights. The turn signals work on both mirrors and they fold correctly.

Gotcha. You just snipped the wire for the puddle light itself.

I supply pigtails for that part . It’ll land onto an open position in the connector and my custom harness will be wired for it.

I just bought a 2016 Sierra yesterday. The dealer listed it as having power folding mirrors, and it has the button for folding but when I press it I just hear a click and nothing happens. It has the towing mirrors on it. How can I tell if they are the DPN or if they're the DQS but just not working?

Take the door panel off, unplug the mirror and snap pics of the mirror connector so I can see the pins. Only need to do one side...

OK, so I finally got around to installing the door harness and re-pinning the BCM (early 2015 2500hd)  that I ordered months ago. Everything works correctly on the driver's side, power fold - blinker - cargo/courtesy LED light - amber running light. On the passenger's side, everything works with the exception of the cargo/courtesy LED light. I am at work today, so can't pull the passenger side wiring apart until later, but if everything looks ok, is this a common issue (like, hey - you missed this step) or is it possible the LED light is bad. If it is a bad light, can those be changed? Thanks!

Kevin, one way to test the light itself is to use a 9V battery or 12V (if you have one) and apply direct power to the light and see if it comes on.

Unplug the mirror from the harness and see pic.

Apply + power to the cargo light circuit and - power to the ground and see if it lights up.

Found my problem. Cargo light pin wasn't seated correctly. I pulled the plug, re-seated pin, and everything works as advertised. Awesome mod!

I have a 2017 Silverado 1500 LTZ and I want to add tow mirrors and keep the power fold and defrost option my current mirrors have. Is there any tow mirrors out there that will just plug and play without having to do any harnesses or re-wiring ?

Most power fold tow mirrors will have new lighting features. So if you don’t care about those lights working right, then the heat, power adjust, power fold with be PnP.

      so i have a 2003 sierra and the signal and defrost went out of the passenger mirror, so i bought a new glass and the signal didnt work, so i returned the mirror and got to looking into a whole new mirror. i looked at my build sheet and it says i have power folding mirrors, which i didnt know ! i bought the truck used. once i recognized this i tried to fold them in and it didnt work. the production code in the glove box says i have DL3 mirrors. so after all this i just want to know if i have power folding mirrors and maybe there broken? any thoughts or advice and maybe the best place to get new mirrors or mirror
       
      thanks

      Hello Everyone,

      I wanted to start this thread as a continuation from my DL8 to DL3 Mirror Conversion here.

      http://www.gm-trucks.com/forums/topic/190736-2016-silverado-lt-dl8-to-dl3-mirror-conversion-finally-complete-3/page-1

      Based on the 6 months of research in the above thread, feedback from many of the members here, and observing behavior of other member's experience...


      I am now able to officially offer a Plug and Play Harness Solution for those that want to upgrade their Standard DL8 Mirrors to the DL3 Mirrors on their 2014* - 2017 Silverado/Sierra Trucks (LT/SLE Trims).

      DL8 Mirrors - Power Adjust, Manual Fold, and Heated
      DL3 Mirrors - Power Adjust, Power Fold, Heated, Auto Dim (Driver's Side), Turn Signal and Puddle Lamps

      This has been tested on the following models:

      2014* - Silverado/Sierra LT/SLE - 1500* (Known issue with Puddle Lamps - Diode mod workaround required)

      2015 - 2017 Silverado/Sierra LT/SLE

      Please see Vehicle Acceptability for Retrofit Document Here. Keep in mind that this document is intended for Towing Mirrors, but based on feedback, they seem to follow similar acceptability requirements.

      https://www.dropbox.com/s/q4eldhgg2x8i10q/Camper%20Mirrors%20-%2023371780.pdf?dl=0

      There might be additional wiring needed for other trucks. If you decide to purchase the harness anyway, I can assist as much as I can. However, there is no guarantee that it'll work without BCM/Memory Module Calibration (and if that's even possible), or additional wiring for missing circuits in the inline door hinge connector. Also, if you are outside of the compatibility requirements, I would need some additional information/photos of your truck connectors to determine if this harness will work or not.

      The Plug and Play Harness will be pinned for the following functionality.

      Turn Signal
      Puddle Lamps
      Power Fold***
      Auto Dim (Driver's Side)****

      ***For Power Fold, you will need a new Mirror Adjust/Power Fold Switch - Part # 23154702.

      ****For Auto Dim (Driver's Side) - You will need to add a Auto Dim Rear View Mirror AND run the additional (4) Circuits needed to the X51L Fuse Panel and X61A Junction Box. Please see thread here for details.

      http://www.gm-trucks.com/forums/topic/192050-a10-inside-rearview-auto-dimming-mirror-conversion-dd8/?hl=a10+mirror

      The Harness Set for both Driver and Passenger is $225 Shipped (lower 48) via PayPal (as Family and Friends). I ship USPS Priority Mail 2-3 Day Shipping. Once you receive the Harnesses, Install, Test, and Confirm all is operational, you have the option of shipping me your Stock DL8 Harness for a $40 Core Refund.
