I have a 2017 GMC Yukon SLE with DL8 Mirrors - Question on the Escalade Mirrors Upgrade.

Don't know if you get more in an SLT or not so it may be more plug and play for their trim package.

Do you have to do anything to the door harnesses for the these to work?

I would prefer to remove the door panels one time if I can help it and have everything needed on hand.

I have the Convenience Package, and Enhanced Driver Alert Package if it matters and would like as much function/features available in the Esky Mirrors as possible.

Ok. DL3 gives you all the perks. Heated, power, blind spot and turn signal. Meaning your ride needs to be dl3 as well as the mirrors your plan to install. The camera on the Esky mirror will not be used.

I'm talking about wiring harness from DL8 to DL3 in an SLE trim 17 Yukon.

I know there would be very little issue going from SLT DL3 to Escalade mirrors. (Plenty of posts there will be no camera)

My question is will the SLE door harnesses have the wires to Plug n Play DL3 mirrors minus the memory

I'm looked for heated, pwr fold, power adjust, blind spot, puddle and turn signals in the very least.

Had DL8 on my LT - each feature you speak of is separate.

The non PNP: The blind spot needs a radar system, so its a lot more than just a harness, but I will say the 75% increase in mirror size does a lot for blind spots alone. The turn signals and the puddle lights each require extra wiring - cmatt was doing custom harnesses if he is still on here. I just wasn't interested in pulling wires through the door bundle.

The PNPish (that require plugging in new switches as well): Adding the power fold switch gave me folding mirrors. Adding the correct passenger window switch gave me mirror memory. Neither required coding.

I believe most LTs came with the Luxury Package (mine didn't), and that adds the DL3s, so GM may just use 1 harness in LTs. Not sure if the SLEs Yukon had the option. In any event, just the size and OEM fit is worth the upgrade...

you probably just need dl3 mirrors without uft, the door harness and door switches or maybe just the mirror switch.
I added dl3 mirrors to my 18 silverado I needed the mirrors, harness, and mirror switch. I bought everything from the harness doctor. I got credit for sending my old harness back because he add's the needed wires and re-wraps it like oem.
everything was plug-n-play

So, bought a nice used pair of 2017 Esky mirrors, received them yesterday and installed today.

Also bought a mirror switch to swap out.

Upon first test the turn signals and puddle lights work on both mirrors but no fold, no 4way adjust on either mirrors and the passenger window does not want to roll up or down from drivers door switch now.

Any ideas on what might be wrong before I take both door panels back off.

Was thinking about plugging in the old mirrors and running the 4way test with the old switch to start with and also see if the 4ways will work on the Esky mirrors.

Just to be clear, you replaced the driver AND passenger window switches, correct? The driver added the fold button, while the passenger synchs with the driver side for memory. It made no sense to me, but you had to buy a new passenger window control to make them work correctly. I recall someone saying you had to fold and unfold 3X for them to work, but mine folded right away. Of course, SLE may not be compatible...

I only changed out the mirror switch to gain the power fold options (no window switched were changed).

I do not have seat memory option so does this matter for memory (I did not think there would be any memory without that option)

Also it I press either mirror button I do not see any led lighting on the buttons themselves.

As for the SLE - yes I wondered that too but why would I at least not have the 3way adjust like I did before?

I do love the size already, backing in the garage was a completely different view on the passenger side for sure already.

To put all the info in one post:

2017 Yukon SLE Factory Options - DL8 Mirrors (heated, 4 way power, no power fold) Convenience Package, and Enhanced Driver Alert Package if it matters and would like as much function/features available in the Esky Mirrors as possible. ( I understand the cameras will not work and not an issue).

Purchased 2017 Escalade Mirrors they have the lane alert in the corners - turn signals and puddle lights are working but no 4way or pwr folding, passenger window not working from the driver switch.

After some diagnosing what Pins should I be looking for in the event missing wiring is the actual issue?

Not sure if GMC includes more in their harnesses or not but interesting the turn signals and puddle lights are working.

Diagnosing update:
Each Window will only work from its own switch (Master Driver Door Switch will not operate any other window) Swapping another Master Switch - same results

Swapping back to original DL8 Mirror Switch and connecting DL8 Mirrors back to the door harness - 4 ways do not work on either mirror.

DL8 Mirror Switch and connecting Esky Mirrors - 4 ways do not work either mirror.

Further visual inspection of the backside DL8 and DL3 connection plug keys do appear different as in the DL8 has a single large key and the DL3 switch has a split two notch key. (is this a possible issue, are there more than one DL3 switch?)

If the switch was wrong could this be why my Master Window Switch stopped working?
Is there any type of reset?

Master Window Switch solved - It ended up being a blown 10a fuse, specifically #18 "Mirror Window Module" fuse in the drivers side fuse panel.

4 Way Mirrors now work in both mirrors with the DL8 non-folding switch, Turn Signals and Puddle Lights also working so far, all of which are new options with the ESKY Mirrors.

So question now - did I get the wrong DL3 Switch and this caused the BWM 10a fuse to blow?

So researching it appears there are indeed two different DL3 Power Folding Mirror Switches.

Trying to determine if the two split notch is a with seat memory switch and the single large notch is w/o memory

Hi Art. Just saw your email.

To all, I build these and other harnesses on the side during nights and weekends around my day job and family commitments. So I don't have a lot of spare time for the forums, but am happy to help where/when I can. Phil (Harness Dr) and I work together, referring customers (trucks for him, suvs for me), etc. I've come close to standing up a website a few times, but worry that the flood of activity (per Phil's experience when his launched) will severely impact service levels. Each harness is hand built by me which can take some considerable time, especially the more complicated ones. The order queue's been pretty active lately and I'm very grateful for that.

I'll weigh in on the mirrors. In true GM fashion, although the circuit types are similar, adding factory DL3 mirrors to the trucks is different than the SUVs. Typically, the GM SUVs (Tahoe, Suburban & Yukon/YXL) will have all necessary wiring in the door harnesses for DL3 mirrors with the exception of the camera wiring. I have seen some exceptions (less than 5). The GMC SUVs will usually also have the necessary wiring in the body harness for things to be plug & play with the exception of the blind spot monitor. As previously mentioned, it also requires radar modules located in the rear bumper fascia. Tahoe & Suburban models that did not come with factory DL3 mirrors will be missing the puddle, turn signal and driver auto dim circuits at the connector to the door harness. The harness I build adds those circuits to the body harness.

For the mirror and window switches, it's dependent on whether the vehicle has the driver memory seat feature. If so, both the mirror and passenger window switch must be swapped out. This is due to how the components communicate with each other. GM routed a data circuit that tells the passenger mirror to fold through a specific window switch. If you were just to swap the mirror switch, only the driver mirror would fold.

If your vehicle doesn't have the driver seat memory feature, then only the mirror switch needs to be swapped out, but it's a different part number, more expensive and the connector is keyed slightly different. You can make the wrong mirror switch fit, but its pins are different and will blow a fuse as Art discovered.

I'll throw this out there... Wiring schematic for the side blind zone alert along with the rear bumper harness mating connectors. Takes a power, ground, data and a signal wire to each mirror. Typically, power and ground are already at the rear bumper connector. So the other three wires are all that's needed in the body harness in terms of wiring. For the rear bumper harness, I recommend folks just swap it out with one that has the additional wiring. You should be able to get it for less that I can build one. You still have to contend with the radar modules and their mounting.
