The rear height sensor will turn the air suspension on if it see's the suspension is too low. One of the rear air springs is probably dry rotted and cracked, leaking air.You can spray soapy water onto the rear air springs to check for a leak.Other air leak area is under the brake master cylinder ht air line disintergrates.Check for air leaks.Once it gets to the desired height it should shut down. A diagnostic check for codes with a scan tool made need to be done to check system operation and integrity.

No, it doesnt work that way, it is set to a calibrated ride height that is measured by the sensor, when it see's it is sitting too low, then it turns the compressor on.You could have a problem with the air suspension relay or an air leak as mentioned.It really needs to be checked with a scan tool to get in depth and diagnosis it right without throwing a bunch of parts at it.If it has an air leak,those parts should be replaced.

Once again a diagnostic check for codes with a scan tool is needed to check system operation.
