Hi, I have a 2006 that currently only blows hot. When we got the car I had to change the direction blend door as I permenantly blew into your face regardless of mode selection. Now this is all sorted, air con is fine with compressor and fan working.
I was told to look at the heater valve? But unsure if this is right. Any idea where this
​​​ is located? Happy to do the work myself but need a pointer of where to start.

​
Thanks
