Black04SS Posted November 21, 2006 Report Share Posted November 21, 2006 The little grill over the drivers left sholder on the headliner is making a noise in the morning when cold.After a few minutes it's fine. Anyone have experience with this ? Black04SS Quote Link to comment Share on other sites More sharing options...
SSS4EVER Posted November 27, 2006 Report Share Posted November 27, 2006 Mine too only when its cold though I always thought that was the mic for the OnStar system. I would really like to find out what the noise is though. Quote Link to comment Share on other sites More sharing options...
tawss04 Posted November 27, 2006 Report Share Posted November 27, 2006 I've replaced a few when I worked at the dealer. It's like a little fan and they just start making noise sometimes Quote Link to comment Share on other sites More sharing options...
CoolBlueSS Posted November 28, 2006 Report Share Posted November 28, 2006 Mine did the same. I just replaced it. It's called an aspirator, and it is part of the automatic temp controll. Quote Link to comment Share on other sites More sharing options...
