My Passenger side window wont come all the way down...It will come down about half way and make a popping sound if i try to make it go down farther....It will go back up and close then make the popping sound again...Does anyone know how to fix this?? Sounds like maybe its hung on something or....**** i dont know! the driver's side works fine

 

i would start my pulling the panel to actual see whats going on when this popping noise happens.

could be jamming up and need adjustment.
