I'm sorry this is my first post but I was finally able to get stationed in Europe and get a caddy . However I now have a random problem. I have the climatronic system and sometimes after I have been driving for 30 minutes or so it will no longer blow out the vents that are selected and it will completely stop blowing out of almost every event. Unfortunately this is my first newer Volkswagen so troubleshooting is a little interesting. I've searched and typically I found that people either fix it and don't reply back to how they fix it or they just do the simple recalibration of the flaps and it works again. I have done the recalibration and that does nothing for me. I only notice it after I start up and drive for about 30 minutes then it does this. It makes it hard to take on a road trip when I can't defog the windows 30 minutes into the drive. Any help would be greatly appreciated.
