Rattle/Squeak From Rear Window (Drivers Side)

When im driving and i hit a bump the window liek rattles or squeakes cant really tell what it is but its anoyingif any of u have experienced this before repla back a.s.a.p thanx....

Well, it (the squeak) could be from any number of things... Could be your suspension bushings, could be an interior panel, could be the hatch, could be the seatbelt, could be the window like you say...

Is it a hatch, sedan, or CRX?

Is the window particulary loose? Can you move it up/down with your hands?

I had a squeak for the longest time, appeared to be coming from the passenger side seat-belt (front), and everyone that rode as a passenger in my car had a different theory as to where the squeak was coming from... Turned out to be the plastic/vinyl door panel rubbing on the metal of the door underneath it. Easy fix, just a bitch to figure out where it's coming from...
