mikes ss Posted April 22, 2009 Report Share Posted April 22, 2009 hey guys, please help me out! on my 03 ss (i believe its my onstar speaker) i have a ticking noise. Sometimes it does it with the radio off and it also does it with the radio on. doesnt matter if i hit any of the stereo buttons it wont go away. ant thoughts at all would be helpful. also it will get loud then start to fade. my stereo is stock and i have never touched it.(other than the buttons) thanks in advance mike Quote Link to comment Share on other sites More sharing options...
kcsilveradoss Posted April 22, 2009 Report Share Posted April 22, 2009 if it is the "speaker" above your head, its called an aspirator, it is part of the climate control system. its basically a miniature fan with resistors wired into it. the reason it is making noise is it is either dirty or off balance. you can carefully pull your headliner down and remove it for cleaning.

Sneakystiffler21 Posted April 23, 2009 Report Share Posted April 23, 2009 Mine usually does that when it's cold out until the truck warms up inside. I thought it was a pissed off Onstar component too. Quote Link to comment Share on other sites More sharing options...

[email protected] Posted May 1, 2009 Report Share Posted May 1, 2009 I'll have to fix that too. Thanks Well crap!!!! I thought it was an onstar speaker as well and it's been buzzing for 3 years... I had them disconnect it when I took it in for service... I guess now I may have the answer to my AC question I posted in an earlier thread... Can anyone tell me if this would cause my AC to either blow ALL cold if set on 89 or below and only blow hot when it's on 90? Thanks, JDA Quote Link to comment Share on other sites More sharing options...

That fan pulls interior air in on a sensor that gives the climate control a reading for the automatic AC control. So that's most defenitely your problem with that.
