There is a module in the engine compartment that has a release valve in it and if this gets clogged or frozen partially shut it will keep the rear jacked up. You might need to buy a service manual from your local parts house to find the exact location.

When the car is parked, air leaks out of the fittings and the car lowers. You have a slow leak.
