Air mixing openings
WARNING: This page is about a different car, the 2004 Volvo S40, 2003 Volvo S40, 2002 Volvo S40, 2001 Volvo S40, and 2000 Volvo S40. However, it is still accessible from the selected car via links, so may be relevant.
Extra air can be taken directly from the evaporator and in to the passenger compartment through the middle vent on the instrument panel. The more the control is turned towards the blue marking, the more cold air will be mixed in with the temperature-controlled air. This function works in the same way as for S70/V70/C70.
HINT: If the heating coil is not used (no airflow through the heating coil), there is no noticeable temperature-difference when the air mixer is open and when it is closed. You can only perceive an air mixture if the ambient temperature is lower than 6-8°C (43-46°F).
