    Exclamation 2005 BMW X3 E83 Blows hot and cold air

    It used to just blow hot air but then I took it to get the A/C recharged. Now when have the Dial to Blue (coldest) and the temperature setting to the lowest, the Dash Vents blow ice cold. Once the car warms up, The Windshield and feet vents blow hot! As if I would have the heater on.
    If I select the button to direct the air through the dash vents only, it blends it and blows mildly cold air.

    The Heater works just fine. What could be causing this issue?

    Thank you!

    The design of the heating and AC system in these cars is that under normal operation there will always be "cooler" air blowing at your face when the dial is set in the middle.

    If you set the dial more towards the blue it will get colder and the opposite will be true for the red blowing warmer air.

    When you leave the system on the auto setting it will blend and adjust the air flow as it sees fit and can blow hot air from the middle at times, but generally there will always be cooler air from the middle vents.
