Air conditioner air flow

It was a bit of a hot one here in Perth earlier this week (37c) so I cranked up the airconditioner for a bit of relief which reminded me of an issue I have been meaning to raise here for some time.

I notice that when the air con is on face/feet setting a good 80% of the air comes out of the two ducts at either end of the dashboard with a paltry 20% coming out of the centre ducts. Is it the same with others?

I'm not sure its always been like this, but it certainly has been for the past few years. I've had the dash apart quite a few times and am wondering if I've done something to the ducting etc to alter the air flow. It still works like a charm, but it seems odd that most of the air flow is delivered to the end of the dash and not out of the centre ducts like most other vehicles I've had.

I've checked as best I can behind the dash and cant find anything out of place, so now I'm wondering if its normal or something that can be rectified? From memory the air flow out of the centre ducts improves if the setting is put to face only, so maybe that explains where the air is going?

Yes indeed, when on face/feet some air will be directed to the floor, face only means all airflow goes to......face

Re: Air conditioner air flow

The dial doesn't control air flow to the side vents. So it won't matter what the dial is set to, if the side vent is fully open, it will always have good flow.

The center vents will have to share their output if the dial says so.... That would be my explanation....

I dont think mine did that. Cant check as i just sold it. Maybe worth checking that the back of the centre vents are seated properly because you may have air going in wrong directions, especially if you have had it apart a few times, cheers....

Re: Air conditioner air flow

yeah my does the same thing, doesnt give out too much air if set to the face/feet..... I dont set mine until the car is cool using just facemode first then i change to face/feet so i get a small airflow in the vents in the middle of the dash. I know not great hey lol

Well on my vehicle, if I set it to Face height, I have the same amount of air coming out on the centre vents as I do on the side vents, (almost gale force) mine is a Grande too, I don't think there is any difference with the air con except I have rear A/C as well. I could only think that you may have leaves stuck in the vent tube to the centre vents, I have only seen this on rare occasions though. And before anyone says anything, yes they do get in, I have cleaned out many blowers that are full of leaves and bugs. I have also had the odd dead bug come flying out of the centre vents and hit me too.
