What did you do to your NNBS GMT900 Tahoe/Yukon Today?

[Fless]

I don't think you need to program it if you buy used.

I think this is correct if pulled from a truck with similar options.

Did you use a pencil eraser on the contacts? It works great. James @swathdiver can probably hook you up with a link to a Tech2.

I'll try the eraser tomorrow. Can't hurt. But I find it extremely discerning none of the 3 functions on that certain switch work but the rest are perfectly fine. My gut is telling me whatever relay's that are built into the circuit board for that function on that certain window position are beat. Or whatever circuitry thingamajigs control it. You can hear a distinct "clicking relay" sound when it decides to work on that side in the switch. You can hear it from the pass door switch too no problem.

I'd be happy just to have a working drivers side window and not the rest, or the door locks or mirrors for that matter. If I could plug and play a new unit just to have that one working to get me by for now i'd be so relieved.

You can also blacken the valve stem tips with a sharpie and turn the motor over a couple times and look at the wear pattern

Yup. This is what I did when measuring for mine:

I was gonna do a "Black Valves Matter" message but I don't think I will.

I DO!!! Please report back! Do you have one locking nub in your hole or 2?

1 locking nub. And the new filler tube sucks just like the old one. It rocks back and forth if you wiggle it. These need to lock on 2 sides. Is there an updated rocket cover/ filler tube combo for that side? BTW check out that awesome rocker! I never get to see those works of art.

I thought that's what this one was. What's the difference? My Denali one has retractable, pivoting covers that close to make an unbroken expanse of fake wood. It looks okay. But the doors take up so much space that there isn't enough room to even put my sunglasses in it. This one is far more useful, and only slightly less attractive. That's a compromise I'm willing to make.

I have the same one with the little doors in my LTZ

Your filler tube looks so tight and solid. So jelly.

an extra o-ring on there really got it fitting tightly.
