Vanner Question - cold air blast

[jeffman164]

I have 2005 G.M.C. cargo van . When driving with the heater off in cool weather , every time that I make a sharp Left or Right turn , a blast of cool air blows in my face . I forget about it until it starts happening again for the start of the cool weather . The first time that it happened to me this year was in Vail, Colorado . Just curious if this sort of thing happens to any of you , or is my van just possessed . Everybody that I talk to about this gives me that look . You know the look . The give that blank stare like you are a fricking Moron or something .

Every time I drive along in the cold with the heater off,
which of course means the vent is open for airflow,
and I make a sharp turn, the sudden change in air
pressure causes a sudden change in pressure within
the HVAC duct work, which causes a rush of air to
exit the air vents and blow in my face!

But I'm feeling much better now!
Wanna watch me pull a squirrel out of my shorts?

THANK YOU Turtle . At least I know that I'm not the only one with the cold air blast . Every van driver that Iv'e ever talked to hasn't had it happen to them .

Oh yeah the old fluid and gravity trick - don't you hate when that gravity thing moves something?

I have a 03 GMC I've never noticed....Now I'm gonna have to go drive around and see if I can get mine to do that.
