Just removing the motor won't help, it's attached to the regulator. He needs to remove the regulator, the regulator removes with 2-3 bolts, and the motor removes with 2-3 - all as one assembly.
Just take a look at it, it's really not that complicated. Once you have the door panel off, peel the protective plastic back and look at what is inside the door(it's all just simply the door, as said theres no separate panel). There are a few (I think 10mm?) bolts holding each the regulator and motor in place.
