Circulation Fan Woes . . .

[Davis Walp <73641.1733@compuserve.com>]

Help!

My 1988 Audi 90 quattro has a circulation fan that is in the throes of death.
It must be a bearing, as occasionally it howls at me from behind the glove box
proportionally to the speed of the fan.  

My local mechanic informs me that it most likely will need replacing, and that
(gulp) the whole dash needs to be removed to access the fan.  I am hoping that
one of you have had experience with this and can share your experiences with me.
Are there any cures, temporary or permanent short of replacing the entire unit?


Please mail me directly at 73641,1733@compuserve.com as my receipt of the digest
is unrelieable.  

Thanks in advance for your help
