RE: Thanksgiving maintenance and 2 questions.. (long)..

Mine makes exactly the same noise. I believe it needs a typical
cleaning/lubricating/brushes renewal procedure. The motor on my car has
two unused fittings that look like they were supposed to have rubber
hoses attached. Maybe the motor was supposed to have additional cooling?
I put a little of Militec 1 into one of these fitting and the noise
disappeared... for about one week :-((( Time to get this motor out.
