How do you service a car radiator fan motor? This motor was scrapped as 'not working', likely because the brushes were somehow stuck, away from the rotor.
Do not hit your motor with a hammer, you'll probably break the magnets like I did. Also be very gentle if it's an aged motor, the PCB substrate holding the brushes can be very brittle.
I was able to release the stuck brushes by adding oil to the spring and use a small screwdriver to poke on the carbon component until it came loose. I guess you could potentially replace the brushes all together.
I added oil to the bearing to make it spin smoother. Opening the motor up and releasing the stuck carbon brush did get it spinning but in the process of shooting this video I managed to cause enough damage to make it broken again.
