SOURCE: 1999 ford Expedition ac problem

Rick, u will need to take your car to get serviced. If your ac is not working properly it might be something inside that needs to be looked at. You might need to replace your heater box.

SOURCE: 1998 Expedition: 2000 Ford Expedition I smell antifreeze with heate...

If you smell antifreeze it may be 3 possibilities: 1. you may have a leaking hose/hose connector , or water pump. 2. your heater core is bad and needs replaced. Unless you know what you are doing I would highly suggest taking to dealer for heater core replacement. The dash and steering colum has to be removed to get to the heater core. This is not an easy job believe me (about-900-1200 job). If you have your heater core replaced then also replace the climate control door. This is good preventative maintenance and also a a dollar saver. I would have a pressure check run on your radiator as a first thought. All you may have is a bad hose and that can easily be replaced.

SOURCE: 97 ford expedition. AC blowes out the defrost not

The air control doors on your vehicle are vacuum operated and shift by themselves to a "default" position [which is defrost] if the vacuum is lost. I would suspect that you have a broken or leaky vacuum supply line near the engine somewhere which is preventing vacuum from ever reaching the control panel. Look for a broken or leaking small 1/8" or so diameter black plastic vacuum line near the rear of the intake manifold area on the engine. This line may go to a plastic vacuum reservoir or it might just go right to the firewall and pass through it with a group of other items [it varies from model to model] If you can't find it you might need to have someone at a service facility track it down for you. Should be a fairly simple fix. Good luck, hope this helps a bit!

No heat - ac stays on blowing through defrost vents

If you have the heater directed to the windshield, the AC will turn on. Move the control away from defrost.
