How do you manually lower the rear air suspension?

The previous owner installed a switch to lift the rear air suspension and I had accidentally hit it and the rear end is now lifted up and wont come down. He had told me that you have to do it manually but did not say how.

Hi under the hood on the fender drivers side you will find a elec aircompressor this is your air susp pump. This pump has a valve on it like the valve stem in your tire bleed air from this until you reach the desired level.

No that is the wrong valve that is the air cond. The switch you turn on to air up suspension push that switch and find where the noise comes from the valve is located on this pump. May be somewhere else on the car but you can hear it
