Golf 7 heater problems

[Kuba Kajderowicz]

Hello, when my AC works fine when blowing cold. Although when i put the temperature up, i can hear something blowing. But no air comes thrue the vents. Only when on recirculation mode. Is this the heater core problem ive heard people have? And is this also a extended warrently item in the EU?

here is a video of the problem.

video won't load for me, but it could be the blend door actuator behind the glove box. Mine went out and made a clicking noise when the AC was turned on, and the heater wouldn't blow any hot air. Should be an easy warranty item, but I got one on Amazon for less than $20 and put it in myself because I didn't want to be bothered with taking the car to the dealership.
