[RockIt]

I generally have the climate control set to auto and it works perfectly. On 3 occasions recently it has developed a mind of its own and blasted very hot air out of the upper vents on the dash, despite the controls being set to aircon and 16 deg. Driving back from work last night it was unbearable and I had to shut the system down completely and open the windows. This morning everything was working as normal. Strange and annoying. Before I book it in to be looked at, just wondered if anyonone on here had experienced similar issues?
