Depends on how exactly your motor broke, you may consider rebuild it yourself in case of worn brushes. It's faily easy DIY job and I did mine earlier this year and have no problem since.
Here is the repost:
Blower motor is under big plastic (aquarium) cover, which goes from side to side under viper blades. Most difficult for me was to remove the viper arms. Hummer method worked for me after all (spray WD-40, unbolt a little bit and then carefully hummer the joints thru the peace of wood). After you remove the cover the rest is obvious.
Regards the motor itself:
My motor started working intermittently and then would start only on cold start or not start at all. At first I attempted to clean under the brushes with electronic circuit board cleaner spray, as it was cowered by graphite dust, but it helped only temporarily.
You may want to double-check the brushes. In my case they were worn out by 75-85%. Replacement of brushes is very easy, since you have the motor in your hands.
I couldn’t find an exact replacement for brushes so I end up buying the closest ones ( $5) from local Alternator/Starter repair shop (take only ones for alternator, as they designed for continuous work). Then carefully sand them to the size and shape of the originals. May seem like a lot of work, but it’s not that bad.
Brushes are rectangles in section 8x9(or10 ? ) mm in section. No longer that 2 centimeters. Cupper lead connected to the brush on the 8 mm side. I can’t remember exact measurements, but you will have your old ones to compare with.
One more thing: you will need a soldering iron to reconnect brushes’ leads to the motor’s circuit board.
