Hi there, my airco stopped working a few days ago. I can hit the airco button and it lights up. But the airflow from the vents doesn't change. So I started to search the net and came upon this post about the FSU and thought maybe i've the same problem because sometimes when i get into my car i can hear a little vent blowing behind the climate control unit (while the key isn't in the ignition). Not very hard though and always at the same speed. But it's not always there so maybe it's the same thing? Or should i bring it to a dealer to get the diagnose first?

Thanx Braz
