well, did you test it?
because you can just test it okay search for a dead bird and then pluck out some feathers and clean it up with a vaumme cleaner or something
You have a vacuum line disconnected or broken under the hood, check in the area around the master cylinder and the vacuum reservoir.

No. A vacuum cleaner sucks in air. A hair dryer blows out air.
The heater blend door is vacuum actuated. You have a vacuum leak somewhere.
Usually is a vacuum problem. The vacuum works through the climate controls to make the vent doors open and close.
Because it blows up easily. And the boom is BIG.

it is a vacuum leak-replace the vacuum line from the right side along the right front-tiny vacuum line probably split
When the wind blows it causes energy to move around and makes objects move.
There is a small vacuum line for accessories in the engine compartment on top of the throtle position sensor that comes off and will cause this problem. very small hose...look on the intake throtle body for the sensor...it will have other vacuum hoses attached there also but this one is easily overlooked cause its so small. Hope this helps
Check for a vacuum leak either under the hood or under the dash Check the operation of the vacuum actuators under the dash
small vacuum hose in engine compartment is cracked
