Ok, so driving down the road, 20 below outside (or felt like it)
rolled the window down for something, and when i tried to roll it back up, it went extremely slow then not at all, so i lowered it and tried again

not until the third time when i assisted it with hand, that it went back up

no problems since, every now and then, even before that i would get a semi slow roll up.

what can i do to fix this? was thinking a stronger motor, but then thought about the battery.

EDIT: i did not notice any binding, i already know about that problem. they just went slow for a bit
