Air Conditioning
 

Ok, hope this isn't a very silly question but is it possible to wire up a 2000Boxster S air con unit backwards (or anything attached to it). When I switch the climate control (air con symbol on) on Lo it blows relatively cold air out. If I then switch the air con unit off it blows out properly cold air like an air con unit should. Ie chilled

The only explanation I can think if is that the switch is reversed. Any ideas?
