Hi, I've just bought a 2006 GC 3 litre Limited. I'd be grateful of some info. The air vents at the side of the drivers and passengers lower legs / feet are blowing all the time, even if the settings are on the windscreen only or head/shoulders only. The other air vents (windscreen, head etc) all seem to be working fine. The speed of the air flow adjusts accordingly with speed settings but I can't stop the leg / feet vents from blowing out air. Please can anyone let me know if this is normal. Thanks for any help.
