Well, that pretty much describes it.

It just fell completely on its own while parked...now it makes the
dreaded grinding noise. Got the cute little treatment panel off thta
has the window switch, door handle, Lock, & fabric on it and have
barely got room to get to the window & track. Is this how I have to
work on it?

can I grab this motor/track off a junk heap, or is that pretty much
impossible?

How much for new? (saw this p/n while searching: 82404-38010) did I
understand that to be for just a piece of the assembly? It really
sounds bad...so I'm not sure what needs replaced... I'm ready to fix
it, but don't know what to buy, or how to get at it other than through
this 4"x6" hole toward the back of the door...and that's not seemin'
too handy for me...

so, how many of you have done this? (and how many times?) While
under "warranty" Hyundai fixed the driver's side front window 3
times...do ANY cars exist that aren't crap?
