This morning it was only -1 and dry, I had difficulty opening the driver's door, and I experienced the same issue with the windows. I got back to my car after work (0 degrees) and the same thing: two window buttons flashing on the driver's side, the windows would not auto-up when the doors closed, and you can't make the passenger window go up or down from the drivers side (you have to use the passenger side switch). I can't wait to see what real winter weather will do.
I picked up some
Kleen-Flo Rubber Care at Crappy Tire. There wasn't much to choose from in this category, but it is silicone (and petroleum) free, so hopefully it will do no harm.
I guess I'll find out in the morning if it works or not. My last car had frameless windows as well (Genesis coupe), but I only had issues with the windows once, and that was forgiveable as it was during an ice storm.
