Hi All

My Drivers side window has stopped shutting properly. It closes but it pops out of the runner (in the top left hand corner as you look at it)

As I shut the door after I noticed it a screw few out. I guess its come out its runner or something. Is the door card easy to take off? I'm no where near a mechanic, but don't mind giving these things ago, unless it it a complete pain in the you know what.

Cheers
Dave
