For the third time, my central locking pump failed. It's always been the same - the relays work well inside the unit under the rear passenger seat, but the motors quit. I've checked to see there is power to it, and there is. No leaks. After two replacements, I'm disinclined to pay for another pump. Is there a source where I can buy just the motor inside it? I can fix it myself that way. Looks like a toy motor, by the way.

Thanks forthe help!
