Back after a hiatus: 2018 Denali Build Thread

[adventurenali92]

Wasn’t able to find any info on here for it, but I know the older trucks were direct swap and the connectors appear to be the same. Worst case, they all look like the same four wires so it should be an easy splice if not plug and play. Ordered this one today from a 2007 through 2009 Escalade that have the stitch on the front. Will post an update when it comes in and I try it out.

Should be a direct swap. All the SUVs from 2007- forward that have the buttons for the manual shift mode in the transmisison all have the same wire pigtail connector from what I’ve seen so far. I had a GMT900 Escalade shifter in my 2006 Denali XL for a couple years and then bought a shift handle brand new from one of the GM online parts suppliers for a 2020 Escalade platinum edition in the maple color, as it’s tan-ish and close to the interior of my truck and that fit directly in and had the same exact 4-wire pigtail connection that the other GMT900 handle had.

Brought it home today! Absolutely loving it after the 150 mile ride home!

Question: the passenger side mirror signal is not working, but power adjust fold, and Blindspot all work. From what I could find on here it seems like the consensus is getting a new glass for it. Can’t seem to find an OEM part and I see a lot of people saying that aftermarket glass has a much dimmer signal than factory. For $80 on Amazon it might be worth a shot, but before I do, hopefully someone will chime in here with some advice. Thanks in advance

Weird that the turn signal LED isn’t working. That’s not an issue I’ve ever seen before. In all the trucks I’ve detailed for clients, or driven or been in, other functions stop working but not the turn arrow. Not to say it can’t happen obviously as yours did. Just weird.

As much as it sucks to pay the OEM price for the mirror, if you can find it, I’d definitely go that route over an aftermarket solution. My drivers side DL3 mirror on my 2006 went all brown and groty looking from the heater fluid leaking into the glass a few years back, so I replaced with an aftermarket part, cuz the OEM ones for my year are still close to $400 a piece…… and the aftermarket one was still like $250…. Anyways the aftermarket glass had a weird imperfection in the glass that gave a funky halo effect, like a fun-house mirror almost. I have read many times here and elsewhere that this is a very very common issue with aftermarket glass options at least where mirrors are concerned. I put up with it but it was so hard to use. Plus it only lasted a couple years so it wasn’t worth the price they were charging on it. I finally had enough with the it and 86ed the bad mirror glass. I was able to pull an OEM part off the same year Denali as mine a few weeks ago at one of my local pick n pull yards. All the functions worked on it but the glass was brown from the heater fluid issue just like my original one had and the aftermarket one. Ironically it was still way better and more usable than the aftermarket part because the glass was right with no weird halo effect imperfection. I got really lucky though two weeks ago when I headed down to another pick n pull years for an Escalade that came in to try and grab some parts for one of my clients with a GMT800 esky that Ive been helping her take care of. That esky’s mirror glass was already gone but I stumbled on a burb with the right glass, grabbed it and the yard only charged me TWENTY BUCKS for it!! Cleaned up perfectly and works perfectly and isn’t brown. I was so stoked that I lucked out with that. lol. your truck is too new I’d think for a pick n pull yard to be a solution but hey never hurts to look and see if any of your local yards have any in your year range.

Appreciate the input. I’m going to test that it’d getting power this weekend and then if all good order a used oem glass from eBay for now. I’d like to do the Escalade mirror swap down the line

Great news! That’s what I assumed but wasn’t able to find anyone who’d done it. I’ll probably throw up a thread for it when I get it. Hopefully tomorrow

Always good to check that first! I have fired the parts cannon before checking for power continuity first many times lol.

I really the Escalade mirror upgrade on this gen truck! Looks great!!
