One motor works and other doesnt: Programming issue?- Jaguar Flashing Red

[Team 2524]

For the first time, we drove it around and it worked fine until i switched the PWM cables while it was still live. The right side of the motor went haywire and it just kept on going. The jaguar is still supplying electricity but the LED is not on.

I tried to deploy a blank project and it didn't work.

We switched Jaguars and now it's flashing red. We covered the fault conditions.

I think I did something wrong with the programming but, I don't have the slighest idea where to start.

Sorry If this seems very confusing but, if anything seems unclear about my explanation please ask.
