Broken Electric Mirror, Help!!!

[Daniel R]

I took my 2000 S to be washed and when it came back the driver's side ( passenger side for you guys in the U.S.) mirror was broken.

The electrics work for up/down adjustment but not for left/right, although the motor sounds like it is working just fine. I assume it is just some sort of clip at the back that has come loose, or if it is broken perhaps something epoxy could fix, but I cannot work out how to take the mirror apart.

Any advice from someone who has pulled a mirror apart before??

Thanks in advance.
