You certain its the motor? The blower resistor is a more common failure.

 

Wouldnt it still work on high if the resistor failed?

 

if the fan only works on certain speeds then the resistor is bad

 

Lubricate as you have & then take a big screwdriver and pry from the bottom.

"That wheel usually comes off best if you pry from beneath it with fingers or a pry bar while somone hits the shaft with a hammer and punch or disposable Phillips head screw driver in a pinch. Use some penetrating juice and it should come off."

 

Yes, the motor itself is dead. Turn to high, no air. Bang something against the motor and it starts, but blows very weak. Makes mechanical ticking noises.

Nice. Wish I had seen this earlier to try...I broke down and ordered a unit from BAP that should come with a new wheel. Praying it arrives tomorrow.

 

Backside/bottom of the motor where the bulge is. That plate should come off revealing the brushes.
