Iv replaced the climate control module yes.
bought used fan and that came with a genuine fan control module aswell , part number for fan and module was: , 1K2820015E, 3C0907521B
i also bought a aftermarket fan control module from ebay which was about £20 the part number for that was : 3C0907521F
i'm not sure if there's a certain fan control module i need as the one on the original fan doesn't have a part number
Also mine is a dual zone
