Help needed: Airmatic constantly on high, level error message.

Any ideas what could be wrong would be greatly appreciated. The forum search did not produce results that seem to describe my particular problem. I do not have access to Star Diagnostic, and the next workshop that may have one is far, far away.
Thanks a ton!
[Embarrassed Look] How can I unambiguously determine whether or not the compressor is running? [/Embarrassed Look] If it wasn't running, shouldn't the car be in the low rather than the high setting?
The best-case scenario that I wasn't really daring top hope for.
The indy found a broken wire, fixed it, cleared the codes and everything is back to normal. I am a happy camper and will not push that button unless I need more clearance -- which has come in quite handy a couple times in this crazy winter.

For the record: Now that the behavior is back to normal, I realize that the car was sitting much higher than at the regular High level setting. At least twice the normal difference between High and Low.
My earlier statement that the suspension feels normal may have been incorrect. After the streets were covered with snow less frequently last week, it appeared to me that the ride was stiffer than usual.

Why would they send it to an alinement shop?
