Front left window channel a bit messed up so as window rolls up, it doesn't stay in the channel. Shop adjusted the mechanism, but window channel has been damaged. Who knew it would be so difficult to find a channel. Finally ended up purchasing an entire driver's side door. Couldn't find something local so had to go on fleabay. $500 later - argh! But at least I now have an entire door - window, mechanism, etc - when things go wrong.
