Ok well i have had ALOT of experience with the Level Control, my 92 cadillac i had to replace everything from the struts to the compressor, gets a little costly, anyhow if your compressor is running every so often then you have a small leak somewere, it should not come on at all when the car has been sitting for more than 7 minutes or so. It is always active, meaning that if the ignition is off the compressor is still hot (has constant power) the best thing to do is get a bucket and sponge and some mild soapy water and start at the compressor head and cheak for leaks, at all the fittings and around the bags on the struts, it could be as simple as having a bad O-Ring on a connection, some dirt or something, or it could be as crappy as having a bad strut. That last one i can tell you sucks, struts- not to expensive, 4-wheel alighnment, sucks. Well good luck guys. hope you get em sealed up.
