Correct. They are probably worn down to nubbins and the springs can no longer push them solidly against the commutator.

Not necessarily. You may be able to replace just the brushes, or have an electric motor shop do it for you. They could determine if it's viable to rebuild the motor for a lot less than the cost of a motor. If it's shot, you're only out a few bucks. If it's salvageable, the repair should be MUCH less than a new motor.

You can DIY some of them if you can find brushes that fit. I've replaced blower brushes in GMs before, using alternator brushes, but I have yet to do a BMW blower.
