[V8] Blower Motor cleansing

[Roy Hall]

The Blower motor for my 91 - V8 has started to run erratically.  This 
car is my daily driver and performs flawlessly however now that summer 
is coming I need the AC.  I have read the archives and seen where some 
have been able to "clean" the brushes with electric cleaner.  My 
problem is now that I have removed the cowl and am looking at the 
blower motor - through all sorts of ac lines and electric cables and 
the wiper motor.  I don't see how to reach the motor nor do I see the 
breather tube that needs to be removed.   Anybody BTDT or have any 
pictures.  I also read of sending some lube into the air intake.
Any and all suggestions would be appreciated.
Thanks
Roy
