I had that problem. Whatever fiberglass insulation they use inside the dash had wrapped itself around the motor shaft on both ends, binding it up. Other than that and dry bushings it didn't seem like there was anything worn. I just applied a few drops of transmission fluid to the bushings at both ends after I removed the insulation from the motor shafts and reinstalled, works like new.
