I have problems in which the passenger side door rattles and it sounds like something in the dash squeaks when going over bumps, any ideas?

 

How many miles do you have on your car? If you have noise in your door, remove the door panel and check for loose stuff or missing stuff.

Also these dashes are known for their squeaking. Do a search to find the solution for that problem.

 

92,1xxx miles.

 

That's not a lot for a squeaking dash. Maybe someone removed it for some reason or had their feet up there or something.

 

I just pulled the long padded trim piece that buts up to the speaker off of my driver side door and found the two torx screws loose. The washers beneath them were rattling around and ruining my zen on the freeway - it sounds like at least one of the rattles you were looking for...

 

I just fixed my squeaking dash. what a pain but it now seems like a totally different car...lol...
