I have manual windows and the passenger rattles/vibrates when I go over a bump,hill,etc. and does it more if I sit at idle.Its driving me crazy! Any ideas?

 

I would pull the door panel off and see if you can find something loose there. You also might be able to adjust the window runs a bit. Usually the holes where the bottom bolts go in are slotted and the runs can be moved a bit to tighten up the window.
