BMW Repair: E46 heating on windshield, zlatko, windshield

Question
Hi, i have a 1999. E46 320i model with automatic A/C. When i turn the ventilation on to legs and in front of me, the air is coming out as i want it. But if i turn the ventilation on windshield it is always blowing really hot air (the temperature is set to 21°C).
Do you know maybe the reason.
Thnx.

Answer
Zlatko, why would you need cold air on the windshield? I believe this is the way the system works but I would have to test a car or two. Try a friends E46 car and see if it does the same thing. I believe it does this for defrosting even though the defrost isn't pressed.
