For awile my window would stop when it was going up, but it didnt happen very offten. After it would stop i could press the botton agian and it would continue to go up. Just recently it stoped and wouldnt go up and then once i got it to go back up it would go down then up then down. Now i dont dare to roll it down. Now when i close the door and it goes up into the top of the door it goes up then down then up...etc. Sometimes it does it for a minute and other times it does it for awile. it even will do it while im driving. SO whe took my door panel off and its not the motor. ITs not the switch either because its new. So it could either be the relay or a controller module thing that goes under the glove box near the cabin filiter. I found out that part isnt cheap and the bmw shop has to code it for my car to get it to work.
I want to know if anyone has had this problem or has heard of someone having it. Also what fixes it because i would prefer not to buy the controller module thing if i dont have to.
I need some help
Its a 1995 318is
