Stop express window down sooner
With the door panel off, I noticed the motor/track are binding and pushing out on the inside of the door. I replaced the motor, which uses bolts/nuts to replace the old rivets. The bolts/nuts are listening and widening the holes in the the plastic/fiberglass door frame when the express feature tries forcing the window down further.
I read threads about disabling the auto down feature all together, which I’ll use as a last resort.
thanks
It is also highly recommended that you use the shbox method for motor replacement. This will prevent many other types of damage to the door. It will also give you more room for the motor-to-regulator hardware.
You aren't talking about using nuts and bolts to attach the door regulator to the composite door skin, are you? This would be a HUGE problem. That attachment must use specialized rivets from GM. Standard hardware will destroy the composite panel. (structure of the door)
1) Get the proper GM rivets in the door to secure the regulator. They are special steel mandrel/aluminum jacket rivets, made specifically for the composite door. Any GM dealer can get them for you. You'll also need a special oversize riviter that does 1/4" rivets. Menards has a great price on a tool for this: https://www.menards.com/main/tools/h...241182&ipos=13
The rivets are critical. If not used, bolts will tear through the door like this and throw off your window geometry so the glass will not seal:

2) Follow the shbox instructions to drill holes in the panel to access the motor bolts: http://shbox.com/page/windowmotor.html
Then, replace the nuts you have on the motor with nylock nuts. If those things vibrate loose, the motor gear will grind and remove the regulator. This is the way you want to replace the motor in the future, also because the process for drilling out the regulator rivets enlarges the holes in the door. (No doubt, as you found the hard way.)
^^ All of this should also resolve the concerns you originally posted about.

I’m going to add it to my winter project list. I also noticed the pass side window has slowed down, so I’ll grab the rivets and riveter and get to work on both doors.
thanks again.
BTW - The Rivet Part Number is 10157547. I have three if anyone needs a random one. (They come in packs of 5, so for a new project - mine won't be helpful.)

I think when I do the pass side i'll have a better understanding of the internals and go back to the drivers side to see how I re-secure the regulator without bolts/screws. I did, however, get my ds window to seal perfectly around the weatherstripping and being careful about not rolling the window down all the way...but suspect this may not last long
Thanks again.
The GM Service Manual left out a procedure to do this, but shbox (again) pioneered figuring this out when the third gen came out: http://shbox.com/1/adj_window.html
^ You'll want to back track and make sure that you followed this procedure in this order to make sure things don't get bent out of shape in the door.
