5K blower motor

[Swann, Benjamin R. (BSWANN)]

I was able to successfully rejuvinate one by cleaning the brushes and
applying some di-electric grease to the armature contacts.  Only did the
upper brush, as the lower was a PITA to get to, but that did the trick.

Had the exact same symptoms as yours.  after the fix, it kept working for
several months, then I sold the car.  I bet it is still going strong.  

That reminds me, I should apply some di-electric to the armature in my
5kcstqw as a pre-emptive measure.

<My  question is how long is my blower motor likely to last once it
starts making a squeaking noise on right turns?  It had been quiet and
working well for 4-5 months now, but just started making noises on right
turns.  The noise goes away after a min or so, or the next left.
..
Any histories out there as to how long a blower has once it starts
making noises like this??>
