Quick question...with the GT Luxury comes the standard rear air vents with fan-speed control. It seems ours only blows cold air. Are they supposed to blow heated air too (ie when the heater is on). Quite the p*ss off if they're cold air only. (pissed)
Use dash vents and angle them up and over / above your head so it flows over your head and heats from the back to the front. The headliner in the Premacy (5) is high up and flows... large roof is like a wind tunnel, made to flow that hot air back there
