Is anybody else having problems with the climate control? First bit of warm weather and I felt the need to crank the air con on. Flicked it down to 16 and over ruled the auto by cranking the fan up to max. Best I got was slightly warm air, no way is this going to be man enough to cope with the summer proper.I have no issues with the heating, just the aircon side. Do people think I might have an issue or is it just a crap air con?
