Do you have errors showing up in the diagnostics windows that help?

What value is the limit switch if you probe the wire? If you probe the value going into the motor? This will help identify whether it is a SW or HW/Electrical issue.

Also, if you put the robot into Test mode, you can scroll to find the Pullback motor. You can see the value that periodic updated with. You can also set the value yourself if you want to run the motor a bit. Keep in mind that unless your code reads the robot mode, periodic loops tend to operate even in test mode, so the interactive motor set features may be overwritten by periodic.
