2015 towing mirrors

bbarn3s · December 13, 2015

So your problem is only with the clearence and reverse lights, not powerfold then? Sorry if I read your post incorrectly.

That's correct.

I have the amber clearance lights wired as blinkers for now, but I would like them to work as clearance lights as they are intended to be use.

Everything I've read says I just need to swap out the door harness with the ones sold by GM (23171564 & 23171567) as well have the memory module flashed with new CALS.

The service manager at my local dealer says he has personally performed 2 of the installs without a hitch. The one he is working on now, he can't get the passenger side clearance light to come on. Because of that fact he refuses to work on my truck. Hopefully the other dealers I've left messages with will be willing to dive into this project.

If not, I'm going to run my own wires into the doors and hook up the clearance and reverse LEDs.

Here is your problem the Driver Door Harness - 23171564, Pass Door Harness - 23171567, and the "RZY" - 23387133 accessory harness are only designed to be used with the S4O/Chrome/23372181 and S4Z/Black/23372182 Mirror kits Like I am having installed on my truck that are manual fold only, So that leads me to believe they do not have wiring to support power fold Mirrors so even with the harnesses the power fold function would not work and would have to be wired in on your own. So far I have not heard of anyone who has put the power fold mirrors on and got them to be simply plug and play without extra wiring and replacing switches etc. but I may be wrong. also without the kit you don't have an authorization code to allow the dealer to reprogram the BCM to accept the mirrors witch may add another sticking point as GM has locked down on unauthorized dealer programming in these trucks.

You cannot get the power fold mirrors in a kit, only non power fold mirrors are in the kit.

Dealership I bought my truck from installed the DQS power fold mirrors, correct harnesses and reprogrammed the BCM. They told me that GM wanted to see proof that everything was purchased from a GM dealer and not from eBay, Amazon or any other non GM dealer.

Since everything was thru the dealer (dealership included the DQS mirrors and everything required for the upgrade from DL3 mirrors as part of the deal) I bought the truck from, there was not a problem to do the upgrade.

Everything works as if it was installed from factory.

It sounds like after you get those harnesses you should be good to go, I am assuming that the harness you are ordering is the one that would have came in a power fold tow mirror equipped truck form the factory.

Harnesses shouldn't be a big issue. Where I need GM's help is flashing the memory module with new CALS.

Hopefully the two dealerships I left messages with will come through. The dealership I purchased the truck and DQS mirrors from wants no part of installing said harnesses and the flashing.

This is exactly what I'm looking for. However the dealership I purchased the truck and the DQS mirrors from wants no part in the install of harnesses and flashing or truck. They are just willing to sell me the harnesses.

Hopefully I can find a local dealer that is willing to help me.

I'm done dealing with local dealerships. Most won't touch the project and the one that will wanted 900.00+ for labor.

I'm going to run my own wires into the doors this weekend to get the clearance and cargo lights working correctly.

Buckalew for sure said no.

I've left messages with service managers at Munday and Lone Star Chevrolet. If either of them are willing to give it a shot I'll be sure to post it here for others in the Houston area.

I just bought a 2015 GMC All Terrain from Beck and Masten and had some aftermarket work done at Cassidy Auto Trim.............that's who does all Beck and Masten Souths work. I would check with these guys.

Installed my mirrors last week. As of right now I only have the power and heat working. I'd like to get the harness so I have the turn signals working.

Got the mirrors installed today. Full functionality! the L.E.D. markers and signals are surprisingly bright at night.

Fantastic! Mine are on the way and I have the same truck as you, built the same month.

Just hard wire it yourself and boom! I hard wired my mirrors because the harness was not out when I bought them

Found them for $505 for the chrome manual fold with authorization code. Win!

Do they come in white or chrome only and I would have to get them painted white?

Half_ton · January 9, 2016

I got chrome so I could wrap the smooth chrome in white vinyl.

I just removed my factory power folding tow mirrors, including the original door harnesses, and posted them in the for sale section if anyone is interested. They were factory optioned on my truck. Thanks
