Rome Duran Posted April 17, 2021 Share Posted April 17, 2021 While driving my car, I have noticed that when the A/C is off, the front windshield vents still have heavy air flowing from them. When I’m in a stopped position, it doesn’t do it. It only happens while driving and I especially notice it when I’m on the interstate. It’s quite annoying any suggestions?

Vtallysx4 Posted May 4, 2021 Share Posted May 4, 2021 Do you mean when the HVAC system is completely off? if so, put the HVAC system into recirculation mode, so no fresh air is pushed through the vent into the car. 1 Quote Link to comment Share on other sites More sharing options...
