blower motor weirdness

[CL Wong]

Patient: 200q20v
I've been trying to diagnose a non working blower motor.  I did a new blower motor and heater core summer of 2007 and really don't want to pull it all out again.

Wiring checks out per the bently.  Motor gets voltage when I set the temp to low and the speed on high.  I can see the brush sparking like it wants to start moving but blower motor won't move until I jump start it with a carefully placed screwdriver to start the motor spinning.  

I have the blower running right now but it's a bit noisy and not as fast as I would expect.  Can I lube this thing or is something else wrong?

it worked pretty good last winter and this summer so I'm not sure what could be wrong.

thanks in advance.
