2012 Ford Fiesta has no air pressure, brand new air filter?

Not sure what's going on with the wife's car. Hot as hell outside but her ac blows like it's on the lowest setting when it's on full blast. I changed her air filter but it didn't help at all. Do these have a cabin air filter? I tried finding out online but can't locate it from the passengers side where they say it is.

Yes.

So your wife's A/C isn't working properly…

You don't really know anything at all about cars, do you?

Snake the vents. Maybe a squirrel built a nest in it.
