How too Door Mirror

I know I am thick I have two books and a CD on the defender 90 but
cannot find how to take apart off the door my mirror its come lose so I
assume there some screws somewhere that need tightening


Yes I know I could take a sledge hammer and knock it off the door

But I only want to tighten it up

Thanks for all replies

Which bit's loose - the head on the arm or the arm on the door hinge?

There's an allen bolt in the bottom of it which tightens a clamp which clamps a ball on the arm.

its the bit on the hinge thats lose, I can see now , got to unscrew the hinge part to get at the mirror screws behind.... Thanks, there bloody tight need that sledge hammer

Pull the door card back and you'll see the nuts on the inner end of the hinge screws.
Easily enough removed with a spanner.
