01 Silverado- Ihave a rattling noise behind my passenger airbag- wicked annoying!!! I have looked everywhere and it is there even with the glovebox completely empty. Anyone have an idea of what it could be?

 

Just a thought, butcould you have possibly set something on your dash and it fell down into the window defroster vent and is stuck there, rattling?That actually happened toa friend of mineone time, drovehim nuts tillwe found it. Other than that, I dont know.

 

thats a good suggestion i will look but it sounds closer to the front

 

2012 Silverado...I have the same rattle, passenger side...defroster / air bag area. Rattle occurs, when engine is turning in the 1150 - 1300 RPM range.

I have placed foam behind the radiator / coolant tank...since is is not secured well (design flaw.) And have zip tied, the transmission dipstick tube...it moves also.

Still have the rattle......any thoughts?
thx
