Alfa 159 air direction issues
I have an '08 159 and I have a really frustrating issue with the air. It seems to be random but quite often when I get into my car and turn on the air, the direction is stuck blowing at me not on the windscreen like I want it to when it's fogged up. This is without using the demist button as I have read that the demist option doesn't work when the car is cold and you have to do it manually. In order to get the direction to change I have to turn the dial to have the air blowing on me and then turn it back to the windscreen setting. However, this doesn't necessarily work first time so I have to keep turning the dial back and forward sometimes it's taken up to 15 minutes before the air will change direction. If it's a cold morning this can be a real pain when i need to leave for work and I can't see through my windscreen. Has anyone else encountered this problem and if so how do I fix it??
Thanks in advance for any help.
