humming sound in left dash
She also has an occassional "humming" sound from the dash which has me mystified?
I have a 1993 300CE and at least once a week and only within about the first 10 minutes of driving I hear a humming sound from the left side of the dash board. It almost sounds like a air compressor. It sounds for a few seconds and quits. Nothing in the car changes. I too am mystified.
Comments?
