raise the ride height button do nothing!!!!!!!!!!!!!!!!1

hello! suddenly, my 2002 s500 is riding lower than normal, and when I press the raise the ride height button, it does nothing, not even turn on the red led on the button. I already checked fue # 9 on left box, and # 46, 31 and 32, all good!.I know there are a million post about air suspension, but I'm missing a fuse location perhaps? the raise height button led not turning on means maybe the ads control module is dead? also,I can not communicate with the suspension module

A failed Airmatic compressor relay is a common cause.

It is common for the pump to go bad, and when they replace the pump they also replace the relay and a fuse! If you can provide me your VIN I would be happy to grab some part numbers for you.
