Front area has a pump or motor running
Strange question, I have a 2007 bus QSP on a FL chassis. I hear a motor/fan or something running near the front. The generator is shut off. Bus has been parked, aired down and jacks deployed. A/Cs off.
Any ideas as to what is running?

Water pump turned on with the water tank empty? Pump will keep running since it can't build up pressure.

Does your generator have a cooling fan and, if so, is it running even though the gen is off?

Many diesel coaches use vacuum operated HVAC but no vacuum in a diesel engine so they install a vacuum pump in front. If there is a leak, the pump will keep running.

Find 12v on/off switch and turn off 12v and see if that stops sound? Dave

Check your fan on your dash air-conditioner make sure it’s off. It will continue to run even with the key off I think mine does
