Coming back from Cornwall today, I noticed the temperature in the car was getting quite warm, so I checked the climate control and set it down to 17 degrees. The fan speed went up but the air was not blowing into the cabin and the car cabin temp just got hotter. Quite a few miles further on there was a change in the fan note and the air started to come through and has been ok since. This did happen before funnily enough on the way down to Cornwall last year, it was raining and the fans were not clearing condensation from the screen because no air was being blown through. it was as if a flap had not opened or something. Was going to look for a fault code with OBD Eleven but got an error message on that "device is not Authorised" Only had the OBD eleven for 2 months, not happy with it. Anyone had anything similar happen or any ideas? thanks
