so i've got my B7 A4 2.0 thru the first year...from last summer to now. and i noticed climate control seems to be acting weird. the a/c doesn't seems to be cool enough, and at times seems to be too hot. during the whole winter, i had the temp. set at 19C...when outside temp is 0-5C.. and the air coming out is hot/warm. where as in the first summer, 19C would be nice and chilly.
the past week in vancouver, its sunny enough that i can test out the a/c again... driving down the highway with outside temp at 16C..i set the temp 19C auto and its full blast for 5min with warm air coming out. then i set the temp to 23C auto the fan speed became slower and cold air came out.

I'm just wondering...is the air temp of the fan relative to ambient temp or cabin temp?
Just want to get some feed back here, before i make a trip to the dealer..

Thanks
