because it's not the best of systems
You think? I've had no problems with mine, and with a Volvo and Merc on the drive with climate too there's no noticeable difference.
Each to their own obviously, just if I have a lazy option that keeps me the same temperature I just use that!
it's not bad don't get me wrong, just some days it seems better than others
Just like my clicking rear axle, squeaky rear brakes and fuel consumption!!
all them problems are worth it tho or are they????
