Faulty electric window on drivers side on 1998 Toyota Sienna

The electric window will not close most of the time without several attempts, sometimes turning a corner or turning the engine off and on gets the window to close little by little. Is this a switch problem or a motor problem? There is no problem lowering the window. How do I access the switch mechanism, does the assembly just pry out?
Thanks,
Rudy

If the window works fine with the engine running, but not so great with it off, I would check 2 things:

1)Check your battery, it could be getting weak.
2)Spray some dry silicone where the window slides, the rubber can get really,really hard and will almost stop a window, especially if the battery is weak. I used to spray silicone at each 30k, and the customer was always amazed at how well their windows worked.
