Rannge Rover L322 Sunroof

[Johnspex]

HI
The sunroof on my 2003 L322 won't work.
I've tried the reset, holding the button down for 20 seconds, but all I'm getting is a slight clonk from somewhere near the motor. I'm pleased it' s stuck shut and not open but I'd like it to work

Has anyone got any tips please?

Bump just too see if anyone has an answer.
