Air-conditioning vents

I have an 06 h3... Is it normal for me to get air coming thru my air conditioning vents even when its in the off position? With the circulation button in the on position is the only way I dont get any air coming thru my vents. Anyone else experience this?? Thanks guys!

RE: Air-conditioning vents

It is normal, I think it has something to do with the positive pressure created as the air moves over the cowl. That is where the air is inducted so its almost like pushing air into your vents. When recirc. is on, the outside air is blocked off so the pressure difference does nothing. Course, this should only happen while driving at highway speed, if your sitting at a red light and air is coming through the shut-off system, that might be a problem, not a big one though.

Topic came before. https://www.hummerforums.com/m_74150/tm.htm

From the manual

(Recirculation): Press the center knob on the control panel to recirculate air inside the vehicle and prevent outside air from coming in. It can be used to prevent outside odors from entering your vehicle and cool the air inside your vehicle more quickly. Press this button to turn the recirculation mode on or off. An indicator light on the button will come on to let you know the recirculation mode is activated. This is normal.

Recirculation is available in the bi-level, and vent modes. Recirculation is not available, and the light will not come on, while in floor, floor/defog and defrost mode. If recirculation is selected in these modes, the indicator will flash three times indicating it is notavailable in that mode.

ONLY if you no longer dig up 6.5 year OLD threads when you ask a question. :rolleyes:
