Window motors are bi directional. The windings to the motor are not grounded so polarity can be reversed. Find a "hot" source. clip a lead from a good ground to one motor lead and touch the "hot" to the other lead. The motor should move the window either up or down. If the wrong way, reverse the clip leads. Disconnect the switch first to eliminate any possibility of damaging feedback.

Depending on the make of car the "ground" changes color. American: black. European: brown.
