1500 Denali tow mirrors

[Sierra50BMG]

I’ve got a 20 GMC Sierra SLT with the power folding, heated, blind spot monitoring regular mirrors. Looking for a part # or vin of the power folding, heated, blind spot tow mirrors. These should be available on the Denalis and select AT4s. I found a site that is working on making some aftermarket ones with a harness but GM does not currently offer anything other than the manual fold tow mirrors. Thanks in advance.

84819537 and 84819536 is what I’ve found after searching and now I can’t find that thread.

I'm no help with part numbers, but they must be available from GM as a crash part -- which suggests they could also be available thru accessories.  

 

They factory installed power fold tow mirrors on my '21 Denali 1500. 

 

What they don't have available (afailk) is power extend on the 1500 tow mirrors.

I think the last year for power extend was the old body style 2007's.  My '04 2500HD had them.  They were nice.

Would love to have power folding tow mirrors on my '20 Trail Boss but they weren't an option on an LT and they are way to expensive to add.  New mirrors, harnesses and BCM programming.

Yes. I believe I found them, however They’re 800 a piece at a discounted rate. Not including the harness. Gm will not sell these as an accessory option. Boostauto.com has some in the works but no eta, they’re listed as 500$ but that could change as they are going through r&d right now. I believe if I got them through gm as a replacement they would be 1200$ a piece and they won’t install it because they are only for the Denali with the cameras. I don’t have the camera function and I read a thread somewhere that the way the different options are wired and programmed causes issues and potentially would not allow anything else to work other than what was factory installed without going through the entire system. I saw somewhere where someone did the swap themselves but I didn’t get enough info, so if someone has done this successfully I am all ears! My passenger mirror got busted on a tree and the garage so I would like to only do a swap one time to the mirrors I want

Can you get the build date on your truck?  Should be month/year on the label in the door jamb that has the VIN on it.

84879428 and 84879427 are the mirrors you need.  84655846 and 84655845 harnesses.

Sweet. Will all the lights work and whatnot?

The rear facing cargo lamps will not work, that requires a BCM update of some sort.  But everything’s else will work if you do the mirror and harness.

Badass. I’ll ask my dealer if they would be able to do the update. I’ll be back. Probably not but it’s worth a try. Assuming the only way to update it would be through the dealer

Any update?

No. I’m going to wait a little while. I’ve been super busy with work and they are pretty expensive. I haven’t talked to the dealer yet. I know there’s some aftermarket ones coming just don’t know when. With the holidays I’m just going to spend 200$ and replace my passenger side with the regular mirror for now. It’s a lot cheaper than $2k. I’ll either wait for aftermarket or pony up around tax season. I’ll update when that time comes.
