Heaters on hot - Help

Hi all,

Bought my K12 yesterday and found that no matter what I put the temperature at on the dial (digital).... It will only blow hot air.

K12 - 1.4 SVE

I'm not the kinda person that likes car heaters unless absolutely freezing so i need to sort this..... Any ideas?

Could possibly be a sticky valve or flap? Don't really know much about k12s let alone ones with climate control lol I'm sure someone else will help out though
