doors windows
My Drivers side door window only comes down about a quarter of the way. It makes a racheting noise and stops. When I put it back up it makes the same racheting noise and stops. I took off the door panel cover and viewed the metal arms and there seem to be a gear permanently attached to a metal piece that runs from the top of the door panel to the bottom . How do I take this gear off and replace it? Where do I get this gear?
