This helps me a little bit with my problem, but mine is a little different. I really know next to nothing about cars. My problem is that a shop took off my door panels to do a window regulator. They put new clips on (well, they charged me for them) and now the door panel is loose and rattles like it's going to fall off! This is very annoying. I don't want to take the car back to have them re-do it because they didn't do a very good job with a couple of other items either and quite frankly, I don't want them to touch it! I have a 1995 BMW 325is.

 Since I am a "car dummy" I need to have some very step by step instructions on what I need to look for, what might be missing (sounds like some kind of plastic or foam thing) and then how to fix it !!!

 I would greatly appreciate some help with this! Thanks!
