Bro YK9 sorry tumpang your thread as I also face aircond problem but with different symptom...


The aircond symptom of my E46 (M43) is that when I take a long drive after 2 or 3 hours of cruising the aircond will starting to blow slower than actual blower fan speed set earlier although the digital aircond blower indicator displays the blower speed at the half point to full (it only blows air as if it is set at 1 or 2 bar speed) and it also becomes less colder than when you just at the beginning of the journey (temp. set at 20 degrees Celsius). if you try to adjust the blower speed higher it will blows stronger but the blowing air will be accompanied with a mist of condense air before slowly disappears over time. The aircond acts the same way when I take a long drive whether it is a day or night time but only occurs during 2-3 hours non-stop long drive but for normal city drive the aircond acts normally without problem. Is this normal or is it a failing aircond symptoms that I need to be aware of?


Pls help me fellow bimmers and sifus. Your advice is highly appreciated. Thanks.
