Hello, I just bought a very nice 2000 Le Sabre Custom, which has the self leveling rear suspension. Normally after I start the car, I hear the compressor humming, then it quits. The other day it rained, and I splashed through some standing water as I entered my driveway. I heard a rather loud moaning coming from the rear of the car. Lasted about the same duration as the normal humming the compressor makes after startup. Anyone else experience this? Something I should be concerned about? I assume the moaning is related to the compressor, I could be wrong. Hasn't rained again, so I haven't been able to reproduce the sound.
Thanks
Scott
