a buzzing noise?

in my 2000 blazer LT right above the driver door on the inside there is this little speaker cover looking thing and there's some kind of buzzing sound when the car is running..any clue what it could be or even whats up there to make that noise?? thanks for any help.

also im still stuck on tires..i wanna get the largest size tires i can go with before a lift is required and such.

Can you be more specific?

Where is this thing you are asking about? Is it on the door or not?

If I remember right it is a climate control sensor, I have the same problem with it. The dealer screwed it up while installing the new headliner and they will not fix it, so I just stuck a pin in the fan blades that are behind that cover

its in the headliner right by the door inside the car. so how come the dealer wont fix it?
