The Passenger side door panel falls off nearly everytime someone tries opening the door and it's really not a huge problem that can't be ignored it's just kind of a hassle whenever I have people with me. How do I fix this problem? I'm not very experienced when it comes to fixing cars but figured asking around couldn't hurt...

 

Look at the door panel and see if there are any little locks that look like small christmas trees, or small metal clips. You can get these aftermarket if there are some missing. We have also used small screws placed sort of out of sight.
