You hot air comes from the water circulated through the heater core. It is like a miniture radiator with water flowing thru it constantly. So by opening the "Blend Door" you are permitting so much of this hot air to pass thru.
Seems like for some reason your heater core is plugged up. Just like a radiator can be. So water may be passing through your heater core but not passing through fully. Your heater core gets hot from water passing throught it from the engine. Then your doors open up, in proportion to how much air is permitted to pass over the heater core.
Suggest to remove the heater core and replace it. Seems the blend doors are working properly but again, if you have a non working heater core then no air can pass over the "Hot Core" for you to recieve hot air.
If you are not mechanically inclined, then go to a local parts store and you can buy a car manual, such as Chilton's or Hane's Car manuals, for your year and make to show you how to replace it. Then you can also have it for any other problems that may arise.
SOURCE: What tires can fit a 1999 ford expedition xlt
I believe it will fit. If you go to DiscountTires.com you can use their site for alternate tire sizes. Especially handy is the feature which shows you the Speedometer error for different size tires. The site will also show you recommended and popular substitute tire and wheel sizes.
The 1999 model had a 265/65/17 as an alternative. You may want to ask the Tire store you intend to use if they can reconfigure your Speedo to be accurate. Some of the Fords can be done electrically without changing Speedo gears.
I did something similar by going from a "60" series to a "65" series in the same width. On my Grand Marquis, I gained 5% mileage improvement, but have to watch Speedo until I get it reconfigured. I hope this helps to answer your questions.

No airflow (cold or hot) through main vent ducts. Can hear the blower working, can feel air coming from in and around the dash area. Seems lik something is blocking the majority of air from coming through the vent openings. They(vents) are open but no air.
