acdii Report post Posted July 6, 2012 When I first get in the car after sitting all day, and it is FREAKING HOT OUT, when I start the car and the nav boots up, then the CC kicks in, I hear the blower, but nothing is coming out anywhere. It takes at least a minute of driving before the vents kick in and air starts to blow out of them. It is as though it has no vacuum to drive the doors. Normal, or should I have it checked out for a vacuum leak? Quote Share this post Link to post Share on other sites
