Hi, I just joined looking for help to reattach my drivers side mirror. It's still on, and still works, but got knocked loose when I was backing into a narrow driveway. It looks like it's hanging on, but is obviously loosened. It really bugs me. I'm afraid it will fall off while I'm driving. My Focus is a 2007 White hatchback SES. Is it possible for me to tighten it back on? Nothing looks broken, the whole fixture is just partially popped out.
