hi guys. we went on a trip yesterday, from Newcastle to Sydney, about 1/12 hours, 140kms away. all working fine when we left, but after about 1 hour 15 we started getting hot, and discovered that no air was coming from the vents. the fan still worked at all speeds, but no air was coming out anywhere.

we parked the car at our accommodation and took the train into the city for the day. next day about 16 hours later we started the car to come home, and the air con worked fine, no problems at all.

Any ideas, thanks
