Y axis motors making noise but not working

So I have been doing some experimenting in preparation to adding a z axis and I’m having an issue with my Y axis. The motors make noise, the driver is getting warm but they will not rotate with the Y axis buttons. Just by accident I found that they will rotate with the Z axis buttons but only in one direction. I have switched the motors to the X axis, proved that they work, I have swapped drivers and they do the same thing. I’m almost thinking there may be a short in the board itself. Anyone have an idea that I could look into?
