My heater/AC is always blowing. When in the OFF position I always have a small stream of air blowing. Anyone else notice this? I have not had it in for service for this problem yet. Was just curious as to who else may have noticed this on their beast. Thanks.

try the 4th control knob on the a/c panel, turn it clockwise.
Ya mean the air flow/exhaust vent, far right side? That does in fact stop it. BUT, the manual says not to leave it in that position for long periods of time. Hmmmm.

I don't see how having it on re-circulate is going to hurt the car. But then again I'm not a HVAC expert.

When you have the path from the outside (base of windshield) open to the inside, especially if there is a window partially opened, there will be a slight flow even if the fan is off. It's similar to leaving a window open.

Placing the far knob on Recirculate cuts off the path from the outside air.

The reason the manual speaks of not leaving it in recirc mode is they don't want you to use up all of the oxygen in the car and pass out. If you are careful to open a door, or a window, at least once every 4 or 5 hours, outside oxygen molecules will rush in. Be careful to not leave the window or door open too long, or you'll get too much oxygen in the car, which can be just as bad as not enough. A good example of a driver who received too much oxygen can be found at any carshow where doors are left open all day. The resulting lower brain functions make the owner think it's okay to install an unpainted bodykit or paint the car pink from a spraycan.

Just be careful, the HVAC system isn't a toy, people can get hurt...
