Answers :

HI, there is a start relay that is located on the compressor unit itself. this relay or, start device has failed. unfortunately, this is a integrated part and, you will need to replace the entire compressor in this case. replacing the compressor unit will restore your Air suspension functions.
This system works like this .There is a air pump located under the hood ,there are air lines going to the rear air bags there is a level sensor.If your pump is running but the car is not rising then suspect a blown air bag either the right rear or left.rear.IF the pump is not running than have the pump checked.
