PWM not responding

[captianjroot]

Today my team was preforming a few tests with the robot. Everything went fine, but after disabling the code, changing something with one of the joystick buttons, and redeploying, the drive motors stopped responding. They're both jaguars, and display a flashing orange light even when the code is disabled. We plugged a PWM from another controller into one of the flashing jaguars' PWM port, and the light went solid. We've checked the code and cant find anything related to the drive motors that is wrong. Is it a problem with the cable itself or with the port on the sidecar?

p.s. all the code's in lab view.
