In Reply to: Newbie questions on use of Climate Control (long) posted by sacman on October 20, 1999 at 19:15:39:

Because the car has a microfilter, no air will pass through it without pressure from a fan, thus no "vent" air as in older cars. The only way to get "fresh" air is turn on the fan and set the temp as low as it will go and leave A/C off.

The rotary dial is used to independently control
cabin temperature and upper-body air vent temperature. For instance, on cold days you may have the cabin temp dialed in at 72 degF, but having warm air blow on your face could make you sleepy. So you use the rotary dial to send cool air to your face only, thereby keeping you alert! If you don't want cool air on your face, then you have the option of turning the dial to the warm setting.

Makes sense to me. I think I read this in that little used publication called the OWNER's MANUAL.

: On a 2000 328i,

: 1. Without the use of the Climate Control, is there a way to get fresh outside air into the cabin, and use thr rotary dial to make the air as cold as the outside air, or have it warmed over the engine? This would be similar to a VENT lever on other cars.

: 2. What's the use of the rotary temperature dial between the air vents on the dashboard front? Does it interact with the climate control at all? For example, if the climate control is set somewhat cold, say 60 deg., and I have the rotary dial set in the hot position, what happens?

: Thanks.
