Look for plugged drains from the air conditioner's evap unit, that is the 
cooling apparatus near the back part of the engine compartment under the

During my heater motor renewal 10 days ago, all I saw was worn brushes. 
The commutator, bearings etc. looked fine.

I had a Saab heater motor sometime ago with the commutator that was shot.
