Howdy. I went to open my driver's side door on a sub-freezing day last week and felt something give in the mechanism and now the handle is more or less sticking out of its housing a bit, so now the door only opens from the inside.

I've gathered from some online research that it's likely that the Bowden cable or part of its housing inside the door has failed, but I'm unclear as to exactly how involved the repair process is. A local indie shop is quoting $330 for the job based on my description of the symptoms over the phone, but if I thought I could save $100 or more by doing it myself I might be willing to give it a shot.

Thanks in advance for any guidance you can share.
