Hi everyone, I have a 2004 Trailblazer that I just bought yesterday and is still under warranty. When I'm driving with out the heat/ac or fan on air is still coming out of the vents, is this normal for the vehicle or should I have it checked out? Any help is appreciated. Thanks.

 

the vehicles are designed to blow air through the vents by letting fresh air in even when the fan/ac is off. [sm=interesting.gif]
