Rear won't raise
I've done a lot of googling and searching, but I still can't figure this out. My 03 is airmatic and has rear arnott air springs without reservoirs. While the front is sitting fine, the rear end has completely dropped. No leaks in air springs and they are still pretty stiff like they are holding air. I can't hear any air leaks and a spray bottle of soapy water didn't reveal any. The air pump kicks on but car does not raise. I have also noticed that the level adjustment and comfort/sport pushbuttons do nothing (not even light up).
Even though the pump is kicking on, could it be too weak to raise the rear? What would cause the level adjustment buttons to go dead? Do they automatically go inoperative when there is a problem with the self leveling system?
I ordered the mb star diagnostic computer last night, but until it gets here I still want to troubleshoot and learn
Thanks,
Steve

I add pressure gauge after my compressor, so can troubleshoot such incidents in seconds with no need for computer.
Both rear bags going together do indicate main line problem.
