Good job, You can obviously see the DC motor and its stator windings inside which look in great shape. I would suspect that given its a DC motor that the fets that drive the motor fail from heat due to high switching currents and high engine temps. I wanted to take one apart in a relatives car but realized the electronics are probably potted or coated so its a moot point.
