I am in the midst of getting a new owners manual since i didn't get one with the car but in the interim does anyone know how to keep the vents open when the car is switched off? The vents are operated under vacuum pressure with automatic controls and i can hear them close when i switch it off. I was wondering if you guys knew some way.

 

And why would u want to keep them open when the car is off? You are correct when you said they are vacuum controled. I dont know a way of keeping them open while car is off without them ever closing opening again on there own.

 

Keeping them open would help mildew from not growing in the vent ways. Plus a constant circulation would be nice too. Just a thought.

 

You have mildew in your vents? Get those old cheeseburgers out of there. Replace your in cabin microfilter to help eliminate that.
