I've been hearing a hard knocking inside my driver's side door when i push the power window button and my window is either fully up or fully down. It sounds like the motor continues to turn, and i'm wondering why it's doing this. I replaced the motor less then two years ago, anyone know what i can do??

 

check to see if the motor has come loose

 

the motor gear may be starting to strip out

 

yeah see that's what i was thinking also, and the damn thing is less then two years old...
