Why does my rear air suspension not pump up?

Did NOT pump up. So it appears that the reason my tail end is high under normal driving is that at some point the rear pumped up when I’d had the trailer hooked up, but never released the air later.

How can I tell if my air bags are working?

When the load is removed and the arm moves down, indicating that the back of the car has risen, the sensor opens the valve on the air bags and allows air to escape, lowering the car.
