Problem with driver side window
 

Hey guys im having problems with the driver side window of my 95 325i...
it will go down but it wont go back up.
i tried to check if maybe it was the switch so i switched it with the passenger side one but still didnt work.
the thing is it goes back up when i apply direct current form a battery.
anyone know anything that could help me fix this or what it might be?
thanks in advance

Sounds like a bad wire connection btw the switch and window or switch and power supply, maybe in the harness where it goes from the car to the door, lots of movement can happen there
