buzzing noise in the small overhead speaker

[SkiUtah]

Has anyone had the problem of the tiny speaker, that is overhead on the drivers side, buzzing? I am not sure how to make it stop. It almost sounds like a radio station that is not tuned to any channel. Any one else have this problem or know how to fix it? If it helps its on a 03 H2.

Thanks again Jason.

Hi that is the onstar mic not a speaker. If your not using onstar unhook it.

Could it be the Air Temp Sensor making a noise ? The mic is near the sun visor and the temp sensor is the one farther back. Just another thought on the possible cause.

Buzzing while underway is normally noise from the plastic around the front windshield not being secured properly.

Thats not a mic its the inside air temp sensor or also called the aspirator. there is a small fan inside that draws inside air inward to monitor temp for the auto hvac controls. If its making noise you either live with it or replace it.
