Electric window on passanger side will go down but will not go back up.

Window on drivers side making clanking sound, getting harder to raise window.

Any ideas on how to test ?:banghead:

NOt going up because of too high friction of because no juice to the motor? Will it do it either when asked for from driver switch and also from passenger switch..?
IN case that helps, this is the wiring diagram:
