Here are complete step-by-step instructions (with photos) on how to test a power window motor to determine whether the problem is in the motor/regulator or the switch/wiring

It would depend what's wrong with the motor... it may be the motor or the assembly.. if your not having any sounds coming from the assembly, then check at the connector if power is actually getting to the motor..In many cases just by opening and closing the door, the wire inside the sleeve that feeds the motor and switch, gets broke , then you have to repair it... The motor itself is a simple motor, nothing fancy, I found a couple of times that the magnet which makes up the field in the motor breaks and jams the armature (the part that actually turns in the motor).. that's why I suggest to make sure that power is coming into the motor. once you verify this and there is, try running the motor without any cables connected.. you could have a jammed cable or dry track allowing the window to pull sideways and jamming it some more.. . if you find that it is the motor, you will probably find that most of them are self destructive, as they are not screwed together, they are assembled and another machine basically folds the metal closed. so to open the motor may make it impossible to re-assemble.
