Hey , I have a question. Does anyone know the trick to getting air in the rear? I have an 05 CS...and with the AC blowing low or mid strenght, theres no air coming from the center rear vents or the rear sides by the door. With it blowing at full strenght, theres VERY LITTLE air coming out to the sides by the door, probably not even enough to put out a match, and a whisper of air coming from the center rear if that.

The leave the blower setting on auto....but i tried putting it on the middle vents and still no air.

Any advice? Is this a problem that has to be fixed via dealer?

Hi

All Cayenne's with single air conditioning system have this problem, there is no fix for so far as i now, only the dual system ( option ) is powerful enough to regulate the interior temperature in country's with a lot of sunshine.

thanks for the reply! well my problem is not even so much regulating or maintaining the interior temperature, as much as it is to get air out of the vents for the rear occupants so they dont stifle to death!!

The problem is to match air diffusers for a single system, the front comes in the first place.

I've got the rear air option - it works fantastic. I think without it there just isn't enough air to go around. Try closing off some of the front vents - more air will go in the rear.

(I'm not sure why every Cayenne doesn't come with the rear air option - I'll never buy another one without it. ...In AZ we need all the A/C we can get!)

To get air to the back, close the two center vents up front and select the air to come through the vents (as opposed to the footwell or defrost up to windshield). This powers air to the back effectively--too bad we have to go this trouble, though.
