[modern] Power Window repair

To all,

The right rear power window in my 91 Sov will not go
down. I have taken the door apart and found that the
motor is bad.
I have taken voltage measurements and it appears that
the brushes are gone as I get +/- 11 volts between the
wires to the motor at the connector in the bottom of
the door well.

I am kinda miffed on how to take the motor out and can
the motor be repaired (non-sealed unit) or do I need
to buy a new one :frowning:
Any hints would be great!!
