VT aircon leak under dash please help

[cartest]

I have a Vt Calais V8,

The problem is that my aircon does not work. I have been told that it is leaking under the dash.
I am prepared to fix it myself, I have been told that you dont need to pull out the complete dash.
Does anyone know how it is done and maybe show some pictures.

Regards
