Cold weather and rear window

[RyanbabZ71]

Ok i have this rattle coming from the back when i hit bumps and such.  Didnt figure out what it was till this morning.  If i tap on the rear window (non slider) it makes the exact noise.  Anyone have problems with the rear window?

Could it possibly be caused by a seat belt that might have the clip rattling against something?  Or is it more like a "pop" ?  Maybe a little water got in around the moulding and froze?

[RyanbabZ71]

no its the actual window.  If i tap on the rear window on the pass side it makes a loud rattling noise.  No air or water is leaking but when it gets cold something isnt right

Have the solid on mine, but no problems.  That's odd, I'm used to the doors making noise due to temperature differences, but for the glass??

[RyanbabZ71]

it sounds like someone is taking the metal part on the seat belt and hitting the window in the bottom corner when i hit a bump (however the seatbelt isnt hitting anything)

 

Its only when it is 20 degrees or colder.

 

Annoying as heck too im scared the back window is gonna explode

I know it's probably not this, Ryan, but don't forget the jack assembly is over in that area too.

Pete its not the jack (its not even there i have a 3 ton in the bed so i removed the bottle jack).  Its the window itself that makes noise.  it didnt do it today because it was 24 degrees.
