HI, i recently bought a vt calais, im having trouble with the heater/air con. i cant get it to work on the face. the air will blow out on my feet or on the front windscreen, but for some reason when i go to face it blows out on the windscreen. i tried another climate control so i know its not the switch because it still did it. and i tried changing the little heater box underneath the dash and that didnt change it either.. if someone else could please help me. someone whos had the problem before or can tell me where to look to fix it. would be muchly appreciated! thanks
