Climatizer only works when I go on the road

Thanks in advance, I tendo a Scenic 2.0 dci the air conditioner throws cold air only when I go on a road or a speed of 70 km onwards. When I go through the city or I stop, I don't take cold air. I have checked the load and it is correct already those speeds works perfectly. That can happen to him. Thank you I wait for your help.

If it works only at that speed I lean to the option that you are only receiving air from the outside as if you had aviert in the control panel the option or figure of an arrow that enters through the hood inwards, and that the air does not work indeed and it is not there is that speed that makes it. Remember that air only works with closed glass.

Look if function. condenser fans
