ac control panel

After having the mechanic in work take apart almost every panel inside my range rover, I am now sure that its the ac control panel thats faulty.
No hot air and only the demist vents work, and the outside temp reading sometimes reads whatever it wants to. As its unlikely that the amount of faults it has are all seperate ones.
Does anyone know where I can get one from in the north west area as a new one is £450.

Thanks inadvance

ebay about £60

ive got a working one, you can have it for 50 plus post. i changed it because i wanted walnut.
