electrical on 2004 GMC Canyon

the passenger side window only works in the mornings briefly, what would cause that?

You must have some sort of electrical problem--could be anything from an issue with the switch to a short in the system. A shop should be able to figure this out with an hour's worth of diagnosis. Ask them if they'll include the diagnostic charge in the price of the repair.
