Hello, my name is***** does sound like a vacuum related issue. The small vacuum hoses are a common failure on this vehicle that will cause this. Under the hood on the passenger side firewall you need to locate the small vacuum lines. They should be plastic. Locate these lines and follow them to the engine. You will find rubber sections that connect the hoses together and those usually break and crack. You will need to replace any failed hoses. If there is a vacuum leak the vents will always default to the floor and windshield.
