Need help with front/passenger power window.

Hey guys can you help me trouble shoot my window problem? My front passenger side power window only goes up when it wants to. It started this past month it has done this at least 10 times now. The window will go down with either switch but not up for a few minutes up to several hours or the next day. Just randomly, some days I wont have any problems.
The connections to the switches are secure and they all still light up with the parking/driving lights on. Can you help me get in the right direction to figuring out what needs fixin? It's getting even more aggravating since I just had to replace a window regulator in my Acura MDX last week. OH, I also just moved from Pensacola FL, to North GA last month when this started happening. It's a little colder here if that may have anything to do with it

Here are some test steps in this thread :

Basically you need to pull the door panel, and test to the motor direct, as it could be an issue with the motor brushes having carbon build up on them.
