A little while ago I asked about fixing a door rattle in my car. It lead to some confusion but after a lot of reading on the forum I ventured out to create this quick fix for one of your door rattles.
All you need is some velcro squares.
This is your door and that plate behind the handle grip will vibrate all the time.
There are two clips on the back of this plate "holding" the plate in place. Located at the corners. Just give it a little pressure on the ends and you should see the plate start to pull out. Don't be afraid to pull on it and squeeze your finger behind the plate to get it to come out. If you are worried about breaking the tabs, watch the video of me doing it.
Once it is off, you will see the clips and the holes were it all lines up.
Take a set of the velcro squares and place them on the flat surface.
Now take the other set and using your nails to make as little contact with the sticky side as possible, attached them to the ones you just stuck on the door.
Reapply the plate and be sure to put it on centered and give it a few good pushes where you placed the velcro squares. You should hear them come to get a little more if you didn't go all out pushing them together in the step above.
Your done. That plate won't move again. If you want to remove the plate later on, just repeat the first step. Its just a little tougher this time. One set should be stuck to the plate now.
