I have a bad vertical scratch on the outside of my driver window. Every time I raise the window, it screeches terribly and scratches deeper. I think it has something to do with the window lift mechanism, but I am not sure, and I do not know how to disassemble for repair. I have removed door panel, and found that the suspected malady is about 6" in front of ext door handle, about 2-3" down from top. From the inside there is a "service hole" right where the scratch seemingly happens - but all I see in the hole is glass, whether the window is up or down. So it seems the window has to be removed for me to go further to repair. Any help would be appreciated.
