The gearbox lubricant fails: it gets sticky like honey and runs into the motor area literally gumming up the works. Replacing the motor assembly fixes the problem. All four of my windows were affected this way.
It might be possible to fix the motor assembly. The motor looks like it will slide out by bending back two tabs on the housing. The gearbox would have to be cleaned out with solvent and re-lubricated. This might not be worth the trouble since replacement motors are under $50.
