Door Rattle - that persistent demon

https://youtu.be/K0sHeHcI3AE

Okay so. Originally when I bought this car the rattle came from the passenger side. Triggered by speed, you reach about 100 km/h and the rattle begins. I got an alignment done on the car and put new tires on and immediately the noise stopped coming from the passenger side, but now it comes from the driver side. When I pass big trucks in the highway going in the opposite direction there is a noticeable influx in rattle. I'm planning on removing the door panel this weekend and seeing if I can recreate the noise by applying vibration to the door. Originally I took apart my passenger door so many times trying and trying to stop the madness and never was able to get it to stop, until by accident it stopped. Anyone else have the same rattle issue? It's for sure coming from the lock mechanism area, the rod back there has lots of play and it sounds like metal on metal, not metal on glass

Factory speakers put back in incorrectly or part of the window track?

Sounds super high up in the door rather than low like where the speakers are mounted but I'll check the tightness when I pull the panel. Window track maybe? Would it alter the sound having the window up vs down? This time since it's on my side of the car I can poke and prod while driving so maybe on the highway if I can hold something right, it will dampen the noise. Very difficult to recreate the noise, I know it will do it going down the highway but maybe it also will sound if I hold a dremmel to the door and turn it on, causing vibration?

is it with the window up or down?

It rattles whether the window is up or down

maybe the window track is loose, or it could be one of the door panel clips or a plethora of things... first step is to take off the door panel and make sure everything is secure. test and if it still persists maybe one of the hinges on the door is loose.
Also just run a bass test with the bass all the way up instead of a dremel, should do the trick

Hey great idea with the bass! I'll try it and see if that makes it rattlr

Tried the bass idea, it didn't work. Hardly rattled the door in the right way, no noise came out. I applied foam to the only piece I could imagine rattling inside the door but it did nothing. Also 20 cents fell out of the door panel when I opened it, wasn't the cause either. Will try again another time
