Why does the front passenger window on my 1995 four door Camry only go down, but doesn't go back up?

Started the car recently and the passenger side
window went down on its own. Thinking it was the
motor, I ordered a new window regulator and
motor. When I connected the new motor, it did go
down, but it still wouldn't go up. Neither the
master switch in the drivers door nor the
passenger door allows the window to go up. All
three other windows work fine.
