Buzzing sound in passenger side door?

Wow, thanks everyone for the fast replies. Looks like I have my work cut out for me I'll see if I can locate the problem using all the info on this thread and report back!

Before you go pulling your door apart check to make sure it's not your glove box door. I tried to find a vibration induced rattle/buzz for months, and then yesterday, while on a bad stretch of road I opened the glove box to see if there was something in it that was rattling. I noticed that the door rattle sounded a lot like the rattle I had been chasing, but different. I put a polishing cloth between the door and the dash and closed the glove box door and the rattle went away. When I got home I put a small felt pad on each flat spot on the door where the rubber bumpers hit, and this was enough to tighten the door and stop the rattle. A slight adjustment to the door catch would accomplish the same thing, but I already had the felt pads handy.
It's worth a shot.

I tried driving with the passenger side door open and still had the buzz/rattle. I think it's in the door itself but it's really hard to tell for sure. I'm thinking it's best to remove the door completely, drive around and see if the buzz is still there. If so then it's in the dash and not in the door...

I found it!!! I took apart my door and that wasn't the problem. I took out my passenger seat and pulled up the rug and it turned out to be a faulty relay, connected to the stereo preamp (40A/30A 12VDC). It sounded like a rattle in the door. The funny thing is that when I would hit the gas or brakes it would make a mechanical buzzing sound which is why I couldn't figure out if it was electronic or just something loose. When I held the transformer it REALLY made a buzzing sound. I unplugged it and the noise stopped (it was SOOO irritating and loud!). When I unplugged it the 'CHECK' light under the torque on demand 4 wheel drive light came on. The car seemed to run OK without the relay/transformer but I'm not sure how important it is. I thought it was just for the preamp which was installed under the passenger seat but it appears to affect the Torque On Demand in some way. Thanks for everyone's help! I'm uploading a photo of the relay to this thread in case someone else needs to know ...
P.S. Turns ut I can't upload photos here so here is a link to the relay:

My relay says it's 40A/30A 12VDC

logan, as faar as i know there shouldnt be a relay under the passenger seat.. do you have a photo of the relay where it was on your vx? that would be helpful in figuring out why its affecting your tod... to upload a photo to this site click on "gallery" from the top bar just under the vehicross.info logo, then on the next page look at that bar again and there will be a "gallery links" option, click that and look for "upload photos" in that menu

Uh oh, OK, I'll get a photo up tomorrow. I hope this doesn't lead down a dark path because I've been trying to get a new in-dash stereo working and it just won't power on. I hope the previous owner of my VX didn't do some bad damage to the wiring...

just curious, was there an aftermarket sound system in your vx when you got it? what does the preamp look like? the TOD computer is under the passenger seat and not much room for a whole lot else..
