Central Locking Vacuum Pump: Repairable?

1989 260E

My vacuum door locks have stopped working because the vaccum pump under the back seat does not appear to be producing suction.

When I turn the key in the lock, and put my ear very close to the pump, I can hear it hum -- although MUCH more faintly than its normal, louder hum, which I could hear from anywhere in the car.

Sounds like whatever motor is in there is failing. Are these pumps fixable, or do I need to replace it?
