03 Odyssey Rear Window Problem

I believe this is a common problem, but nobody seems to have a direct
solution. My rear windows in my Odyssey will crack open slightly, but then
won't close when I try to. One of the two behaves this way; the other is
pretty good either way. What's the suggested solution? Standard motor
replacement? Lube inside the motor?

 

Replace the motors. Otherwise try lubing the motors and then replace them in
a week or two.
