...the vents, is that okay? I own impala 06 Lt since when it come out and I have a GMC Sierra 1500 99. On the sierra i don't have to press the button to close the vents but why on the impala? Oh another thing, every morning is cold is around 27-36F and I turn on the car with remote start and blows cold air instead warm or hot air. I mean does it suppose to blow cold air even is colder out side? and when i ride sometimes i forget to close the vents i start receiving cold air from out side. Do I have to use the temperature slides every time? I mean does this car adjust on his own?
