Buzzing noise under battery tray
I have a buzzing noise under the battery tray inside the fender. it's coming from some type of motor. My haynes/chilton manual doesn't mention this motor that I know of.
if you car is equipped with a trailer tow package the compressor is mounted in the front (driver side) under the fender well behind the bumper. If the shocks are leaking or the leveling switch is no working correctly this pump will run/cycle quite often. Had the same issue with our 96 many years back.
