Just got a z4 and noticed that the driver window only goes down and not up no matter which way I press the button. So I toke the door apart and toke the window motor off and got a new one, put the new one in and same thing happens. So I cut the wires of the window motor and reversed them and noticed now that it now only goes up and not down. Does anybody know why this is Happaning? Do I have a bad button?
 
Sounds like your switch is knackered. They can get wet as the water drains nicely into the door pocket if it's raining and the windows open. Change the switch.

Can the switch from the opposite door be used to just check it?

passenger side only one switch, but no doubt drivers side only has one plug, so I would say no.

sorry to hear...so how hard and how long did it take you to take apart the door... my window won't go up or down, but i was told its the clips...did you use regular trim tools or the specified bmw trim tool to remove the door panel? thx ..
 
no warrenty on the car, but what i did was make a custom switch that will reverse the power - , + . and it works perfect now.
