Here you go, made eveything work in my 2015 Yukon SLE except the puddle lights

Did the harnesses have all the pins in the connectors? I suspect the harneses you got were not the right ones as your original ones would have at least worked the power adjustments.

Your harness is definately missing some of the pins (and I assume the wires). My Yukon's harness had every pin in the chart I posted above.

The pin and wire chart I posted above are for the mirror plugs and harness to the mirrors. The switch plug is different. If you get the mirrors and the correct door switch it should work, but like I said above "Your mileage may differ" but it worked for me.

Also how to remove the mirror switch bezel with switches just pry it up with a panel removal plastic tool

I made up a how-to to remove the door panels on my 2015 Yukon the trucks should be the same with the exception that they have another screw holding the panel on below the switches behind a plastic panel that snaps off. 2015+Tahoe-Yukon+Door+Panel+Removal_1.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_2.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_3.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_4.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_5.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_6.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_1.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_2.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_3.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_4.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_5.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_6.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_1.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_2.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_3.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_4.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_5.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_6.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_1.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_2.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_3.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_4.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_5.compressed.pdf 2015+Tahoe-Yukon+Door+Panel+Removal_6.compressed.pdf

I purchased new DL3 mirrors (23464428 drivers & 23464427 pass) with the power fold, turn signals, auto dimmers, heated and also the drivers door switch (23154702) with the fold button and amber led indicators in the mirror adjust buttons. I just installed these in my 2015 Yukon SLE and they were plug-n-play, no new harnesses, no bcm flash and everything works except for the puddle lights which I personally don't care about. I also don't know about the automatic dimming as I hardly ever drive at night (my Yukon has the inside rear view mirror auto dimmer so the DL3 probably does work). I wanted folding mirrors and the turn signals (they are amber). The mirrors come with no caps and you just pop off your old ones and snap them back on the new mirrors. Here are the pin locations and wire colors, if your vehicle has the wire colors for the folding and turn signals they should work, but your mileage may vary!
