Question for you all....

[Jeepxtreme]

I've got a seemingly silly question... Does anyone know what the little round plastic thing right above the driver's seat? It looks like a small speaker grille... It makes a rattling sound for a few minutes until the vehicle warms up.... No problems with it, just curious what it is..... Thanks

I'm relatively sure its the microphone for the OnStar.

Its climate control. Bluetooth mic is by the dome lights.

Grill above drivers seat

That part is the ambient air sensor it has a small fan internally and a small sensor behind it sometimes you may hear it buzzing, you may be able to use a couple blast of compressed air to clean it
