For some reason, I've got no cold air anymore. The temp setting seems to work OK for heat but when selecting a lower temp (including LO), I just get the fan coming on faster and faster whilst blowing what I assume is air at the outside temperature.

OK, so I know something isn't working right and the question is, is this a warranty item for a car that's 18 months old?

I've never had a car that needed the aircon recharging, even after 5 years, so I'm wary of the local dealing being about to try and charge me silly money for a "consumable".

Any idea's?

Thanks.
