You know how when you open a door or the trunk the light illuminates on the "P" next to the shifter? Well, there is a faint "buzzing" sound coming from here. Any clues will be appreciated.

I have the same problem with my car. Someone on this board suggested it was the small fan that activates when you open the door. This little fan samples the air in the car so it knows what temp the car is and if it needs to heat or cool the car. You will find a little grille below the left temp adjusting button. Cover it with your hand when you hear the noise. This should muffle or change the sound. This fan can get dirty or worn and cause the noise. Let me know if you change the fan or cure the noise. It is driving me crazy. :mad:
