Rattling noise undercar, Window wont stop when rolled up Ok so I have replaced all the accessories, checked with belt off, rev'd the car and still have no idea where the rattling is coming from.
Still present with belt off, doesnt change when reving, doesnt sound like it is coming from the motor. Tends to go away once warmed up. One day after nothing was changed on the car it started doing it. now its almost everytime i start it up.

Also my window driverside when i hold down the roll up switch will bang up over and over where before it would roll up all the way and stop. passenger still works right. Any ideas?

You could also probably let it go a while until the noise happens 100% of the time and isn't intermittent.
Don't use the window until you fix this. Bad things can happen to your regulator. It sounds like someone changed the window motor and used bolts to connect it to the regulator. When those bolts come loose, the motor gear will knock against the regulator gear rack. Lock-tite or nylock nuts should solve the problem.
