servo help!

[Seth Landon Schoming]

I have successfully interfaced my crazy contraption with my wii nunchuck, however, one of my servos only travels in one direction. I have switched it out, etc. and have concluded that it is the servo that is the problem, not the code... Does anyone know enough about servos to advise me how to fix it?

Thanks guys (and thanks to all who helped me with my torque question before!)
