How do i get power to air suspension system? OR what is wrong with it?

What is your question?

Just bought. Needs alternator (killed battery); replacing tomorrow and already have new battery. Rear suspension is up, front is down (remains this way with car running and also while off). Start the car: does not self level, compressor does not engage at all, ESP switch controls in dash do not illuminate (no power to switches). All fuses are still good with verified power to them. Was thinking originally there was a leak but now seems to be an electrical issue. No codes.. however, the dummy light is on in dash for air system. Any ideas and or direction would be very much appreciated. Thank you for your time. Good Day
