I'd need to look at the wiring for a door switch, but I think the wires are on opposite corners to the switch. Meaning the two window motor wires go to two corners, and the other two are going back to the main switch wiring as grounds.
The switches all do two things, one pair of contacts is made, and one wire(window motor) is cut out of the circuit. All wires except the power wires test as ground when no switches are pressed. The switches apply power to one motor wire, and remove the connection to that wire from the other direction through the switch.
From those pictures it looks like you didn't cut the yellow/red wire, you just spliced to it. You cut the yellow/white wire.
The module is made to control one direction of the motor, and that wire is cut and connected to two wires from the module. It sounds like the yellow/red wire is what needs to be cut.
Go back in and carefully follow the motor wires up to the switch. Identify which two they are. One gets cut and the other is just tapped onto by a module wire. If you got those two wires reversed, it should go up automatically. Have you tried to just tap the up button?
