Noise from above thir row seats (like a small air compressor noise)

[cmdias]

OK... this is weird.

Once in a while in ways that i cannot recreate i hear this little noise from the right rear side of my Sedona 2002. Its arround the third row seat and ocupants decribe it as a vibration.

It sounds like those inegrated small air compressors on other minivans.

Lasts arround 4 seconds.

Never under the same ciscounstances.. braking/accelarating/turning.

Any ideas ???? fuel pump in the tank ???

This is kinda funny but I had the same noise that lasted for 4 seconds and it sounded like a compressor or a distant truck putting on it's engine brakes, and would repeat every 30 seconds. It was my rear intermiitant wiper wiping against a dry window.

Not it's almost the same noise but it's not the wiper... i caught that one after a couple of times
