I have a raddle in the dash on the driver side i've pulled the dash panel out but sill can't find it

 

my truck has the same thing... it won't hurt anything it's just annoying as hell. i believe it's a loose firewall bolt or something to that effect.

 

my truck has a rattle too but mine in glass in the defroster from when my truck got broken into 2 years ago

 

haha ive heard it called "the chevy rattle" cause some chevys get rattles that you cant find lmao....but i have a rattle in mine too i cant find....drives me crazy lol

 

mine has started to squeak lately. the only fix i can find is louder music

 

i hate rattle's! i just turn up the radio so i dont have to hear them.

 

Has anyone been able to find the cause of these driver's side rattles? My Sierra has it as well. I'm tempted to spray some expanding foam in there and see if it helps. SO ANNOYING!

 

If it's got Onstar, the cellular module will get loose in the bracket behind the cluster and make some noise. But there's lots of things back there that will get loose, too.

 

my 2000 has it and it was one of the clips that hold the very top of the dash to the sub structure. The molded plastic post that holds the clip had broken off. Looks as if you stick the right thickness of foam between the windshield and the dash top it should stop the rattle and shouldn't be very noticeable.

 

Interesting, might just have to try that on both my trucks
