5000 power windows

[J_T_Douglas%mwcorp1@MWMGATE1.mitre.org]

Arghh.  My "German Jaguar" 86 5000S is at it again!  No sooner had I replaced 
an outer CV boot (and what a painful first time experience that was), then the 
right front window mechanism went kaputt.  It hiccuped when going down for a 
few days, then broke altogether.  It goes down but requires manual assistance 
to go up (and no, its not the switch).  The glass is loose, and can be moved a 
bit by hand.

I'll have to dig into it after vacation, which starts Saturday.  In the 
meanwhile, are there any ideas on what might be wrong?  It helps greatly to 
know the standard failure modes before making my own diagnosis.

Thanks in advance.
