After having my battery die at Sonic Drive-in with my window partway down, somehow the one-touch auto up/down feature stopped working for driver's window. I could manually raise it up/down, but the one-touch auto didn't work.

Turns out there is a reinitialization process you can run though in less than a minute. Works perfect now!

If any of you have an inoperable one-touch auto window feature, try this before going down the path of replacing physical switches or looking for sunroof drain leaks & wiring harness corrosion.

 
You need to operate them manually, one by one. Fully open, then fully closed. The car needs to read the limit switches again.
