The passenger front window is stuck in the up position. I just replaced that motor. on 1996 BMW 328i

Is there a control module? Should I replace that next?

99% of these are a defective window regulator. take the
door panel off and check voltage at the motor while pushing the window switch. if there is no voltage at the motor, you either have a bad window switch or a wiring problem in the r/f door hinge.
so, is the regulator a part that is separate from the switch and window motor?
