All that sounds rather drastic - try the other solutions and then pull the door panel off carefully - I think I have written up the how to somewhere on here there are 3 screws on the door panel and one on the tweeter pod - then it pulls straight off and then up. You can then close the door without the panel on (important - the passenger side controls must be plugged in for the system to work) and see the mechanism as Nater suggests but you will NOT have to cut into the metal - geesh, Nater, you scare me. This is a simple repair but best done with the interior panel off.
