How much air is supposed to come out of the dash vents,floor vents and defogger vents? There seems to be very little airflow out of mine and the interior fan sounds loud with only about four bars showing. Just got A8L back from shop and they replaced the center drains under the heater air box. Could they have messed something up doing this.

Do you get more air if you turn on the re-circ function?

Don't know, will check tomorrow and let you know. Thanks for the tip.

Put sytem in recirc mode but it did not seem to help air flow from vents and fan still makes a roaring sound.
