front passenger window motor

my front passenger power window recently stopped working...whipped out the old multimeter and discovered that there is in fact power coming ouit of the switch going to the motor, and there is a clicking sound as I press the switch up and down...also, reading my haynes manual, I discovered that there is evidently an internal circuit breaker on these motors...does anyone know how I can check this circuit breaker? do I need to remove the whole motor to do so? or is there a way I can do so without? thanx in advance

The breaker is embedded in the brush end cap of the motor. The motor has to be at least partially disassembled to access it.
