[V8] Blower Motor cleansing

[Roy Hall]

Kneale - Thanks for the pic.  My Gorilla hands had trouble getting in 
but once I saw the pic it all made sense. Got in cleaned it and lubed 
it and it seems to be working now.  Just buttoned it up and I am hoping 
I get a couple of weeks out of it.
Thanks again for your quick help - I hope wont need that 55mph AC for a 
few weeks.
Thanks again,
Roy
