alright i have noticed a metal rattle in my driver door of my eclipse, and i'm believing it's the lock because it's been harder to unlock and lock my car, is there a way to fix my lock?

 

take off the door panel and find out why its rattling first

 

I bet you the window guide nuts and bolts are loose. They do that when folks with large systems crank them up all the time. The bass, loosens the nuts and bolts and then the door starts to rattle when you close the door with the windows anywhere between all the way up and all the way down.

 

i'll have to tighten everything when i put my new door speakers in.
