You have an OPEN ground circuit.
Is it possible there was a screw through some metal mounting that you took out that was used as a ground? No, None attached
Perhaps the motor mounting was being used as the ground. No, the Previous motor was mounted to metal rail bit it was not grounded there. The Negative wire from the coach wiring loom was connected to the fan Motor Negative side and there was no connection the the frame holding it.
It is hard to suggest where to ground without a picture but yes, making a new ground point is ok although not ideal.
Figuring out how to run the new ground wire to connect past the broken ground point is where I'm stumbling.
