    Took out car yesterday and noticed when I turn off the AC or turn knob to off air still comes out through the vents, not cold air but warm air. Plus always wondered why the AC blows so hard at first level, there doesn't seem to be a low level. Just a high level then then higher & higher. Is this normal?
    Tia & Happy Thanksgiving to u all!

    If the knob on the other side is still set to work the fan will still blow just not cool....

    And when that is on low it still goes quickly until the temperature stabilises a little

    I'm not sure I explained it too well but you might want to reread the manual

    Above ac on/off button is the direction knob - on the other side is fan speed (ie the knob on the other side) below that is recirculate button - in the middle is temperature

    Drove the car today with the same problem occurring. I know how to turn off the AC and that's what I have been doing but even with the stop button pushed and the control knob to 0 the AC randomly turns on and off while driving. Could it be a faulty AC control unit?
