The small circular speaker directly above the front driver seat rattles every time i hit a bump or anything that shakes the car. It sounds like the speaker is loose and bouncing back and forth, its so annoying im on the verge of ripping the ceiling in the truck. Is there any way to stop the speaker or whatever it is from being loose, or to take out the speaker cover, it looks like its glued,...... Pleasseeee heellppp me

Aspirator fan...


Here is a GM bulletin regarding it...

Document ID# 1639237

Subject: Buzz Noise From Headliner Above Driver - keywords ac air aspirator cover fan grille HVAC interior microphone sensor speaker temperature vent vibration #PIT3511 - (03/29/2005)



Models: 2000-05 Cadillac Escalade

2002-05 Chevrolet Avalanche

2000-05 Chevrolet Silverado, Suburban, Tahoe

2000-05 GMC Sierra, Yukon, Yukon XL, Yukon Denali

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in the PI.

Condition/Concern:
Dealer or customer may comment that they have a buzz or vibration noise emanating from the headliner in an area that looks like microphone or a speaker.

Recommendation/Instructions:
The plastic escutcheon grill, which is round and about the size of a half dollar and located just above the driver to the left, is the interior ambient temperature sensor. The sensor is used in conjunction with the automatic HVAC (C68). On occasions, this sensor has been known to make a buzz or rattle sound. The sensor uses a small fan to pull air over the sensor. This buzz noise may be intermittent.

Although it may not be possible to alleviate all of the buzz or noise from this sensor, Engineering has found that if the sensor is installed incorrectly that it may bind and cause the fan to make a buzz noise. Remove the sensor and while doing so check for any binding. Reinstall the sensor and re-test. If the noise is still present, the sensor itself may be noisy and require replacement.

thank you at least now i know its not a speaker lol, but two things, 1) how do i remove the plastic cover, and 2) the noise is constant, its not intermittent or occasional. I think the sensor might be loose cause its constantly clanking around

its not intermittent though, i think the sensor is loose cause its constantly clanking around, is there any way for me to remove that plastic cover and tighten it or something
