I was wondering if anybody knows if there is suppose to be air coming out from the top vent when the vent on the floor is suppose to be on when you have it on both autos. Because today i noticed that the floor vent and defrost vent were both on but it indcated the floor vent was suppose to be on.

does the display flash when you start the car??

I am not sure but i could go outside and check what would it be flashing and why would it be flashin

The unit is designed to always have a little air coming out from the window vents when "floor" is selected.

It is perfectly normal, because there is a gap in the flap that controls it. It allows for you to always have a little de-fogging prevention in the winter.
