So I bought an 04 MCS last month and have noticed one thing that drives me nuts. If I have the car turned off, but the key is turned on so I can listen to the radio, there is this terribly irritating buzzing noise that comes from somewhere behind the glove box. I tried turning on and off the climate control, and the radio and either way the noise is still there. Anyone have any idea what this is coming from or more importantly how to turn it off?
