I'm new to Mazda forum,I have just bought a 2007Mazda3 5door sport
and as I'm driving,I have air coming out of defrost vent when fan control dial isturned off and modeselector dial is set to floor ordashboard vent
Is this normal or shouldI have no outside air coming in.
This really bugs me as it tends to dry my eyes out the way the air will
follow path of windshield I know I could turn on fan and select dashboard vent but sometimes I don't need fan on.
Thanks in advance for any help or comments

 

First of all, Congrats on thenew ride!I'm sure you'll like it as much as we all do.

It's pretty typical in newer cars to have some air movement when the ignition is turned on. It help the fan from freezing up due to a lack of useage, so it will run at a very low/slow speed. I haven't noticed this situation in mine, or perhaps it just doesn't bother me. I'm not sure which it is.

Have you tried setting the switch to recycled air? Also keep in mind that any settingfrom the footwell setting clockwise to the right (full defrost) always turns on the A/C though the lighted switch will not indicate that.

 

I was trying to get my post out, but the net is too slow this morning......anyway, virgin1 said it all.

I haven't noticed that on mine, now I will have to check it out [8D]

 

Yeah, what virgin1 said.

 

I've noticed this, too. In my car, the volume of air is pretty small. For safety's sake, it isn't a bad idea to have a little air coming out of the defrost vent, to help keep moisture away from the windshield (and thus prevent fogging).

If in the case of your car, the volume of air is enough to dry your eyes out, I wonder if it could be adjusted by the dealer.

 

Hi....thanks to all you who replied.

 

I noticed the same thing when I got my new Mazda3 a few months ago, it is normal.
