Assuming I read your post correctly, and you are talking about the rearview mirror mounted on the door, and your mirror bracket is mounted securely to the door, and your problem is that the mirror head is moving on the bracket, and falling out of adjustment...
Then... The stiffness of the mirror head on it's mounting bracket is set by the screw that mounts the mirror head to the mirror bracket, which is spring loaded.
Soooo... To tighten the mirror head, you got to take the glass off, give the screw a turn or two, and glue the glass, or a new glass, back on.
Life's a bitch...
