Welcome to 2CarPros.
The master switch is directly connected to the driver's window. For the window to go back up, the switch sends power a different direction to the motor (reverse polarity) which causes the engine to run in a different directions; thus the window goes the opposite direction.
The only thing I can think of that would cause this is if one of the wires is disconnected on the motor or the switch or the switch is bad.
First, remove the door panel and confirm that the wiring is in good condition. Here are the directions for removing the panel.
Now, if everything is connected, I need you to unplug the connector at the motor. Using a test light, check for power to the wiring. Here is how it should work. When you press down, one of the two wires will get power. When you press up, the opposite should get power.
Here are a couple links to help with testing for power:
Here are the directions for panel removal. The attached picture correlates with the directions.

Removal and Installation
1. Remove the rear door handle bezel.
2. Remove the rear door window switch bezel.
3. Disconnect the window control switch electrical connector.
4. Remove the 2 rear door trim panel screws.
5. CAUTION: To avoid damaging the trim panel, do not pull directly outward to carry out this step.
Lift the door trim panel by pulling directly upward on the armrest to disengage the panel clips.
6. To install, reverse the removal procedure.
Let me know what you find, if you have questions, or if you need help.
