Passenger side rear above the muffler, it is an air compressor. As long as it stops running in a few minutes it's normal. If you find out running non stop, rust has decayed the integrity of the unit and it's a $500 min replacement.

Not sure about the fuse but there is a plug on the unit. You most likely need to convert it to gas shocks if the pump and original air ride shocks are bad.

This is where it's located at. Pic is looking at the bottom back of the car right behind the passenger wheel next to the indention where the tire goes in the trunk it'll be located above the muffler.
