These cars have a little plastic guide that breaks and sometimes causes the window to exhibit these problems.

In these cases, it's almost always a problem with the regulator. Problems with the motors are more uncommon. The labor to replace is very similar, though. If it's a problem with the motor, you will be out the additional part cost.

I just experienced this problem a week ago, it was a pulley that was broken.
