From the video I watched it looks like a very easy job. Gently pry off the window switch pod, using a plastic trim tool (if you don't want to damage it).
Then check the switch using a volt/ohm meter to check the power coming to the switch (with key on). If power is found then check the switch and window motor using the ohm function and replace the bad part.
If no power is found then you will need to take it to a shop to find out what is wrong. The fact that you asked this question means you should stop at this point.
BTW I'm assuming you have already checked the fuse right :W .
Good luck Don
