Power window problem/question

[Nukes16]

Took the whole damn thing apart one more time tonight. Tried putting a little bend in the channel to reduce the friction at that point. Piece of crap still doesn't want to go up! I'm thinking about trying 2 more scenarios tomorrow night. First, try a new motor, even though I just replaced this one it could be weak????who knows. Secondly, pull the regulator and the vent window from my donor truck and see if that works.
I didn't lube it tonight, though that could be my last resort. Don't really want to get the new stuff all slimy.
