I have a 1998 Ford Windstar 3.8L engine. I am currently not getting any air blowing out the rear A/C in the van. I am researching this on the forum here, but I was wondering if it might be another A/C issue I am having.
Whenever I go up a steep hill the A/C goes from blowing out the front vents to blowing out the defrost vents. Then as I crest the hill it switches to blowing out at your feet. When you get towards the bottom it it switches back to the front vents.
Any help would be appreciated.

Hi
I'll write more later and I'm sure others will chime in, but you have a vacuum leak in your A/C control lines. If you search on A/C and or defrost, or defrost only you will see others have had the same problem. Tracing the leak is the hard part.

When you are going up a hill, your engine is working harder...and the vaccum is lower.
With a vaccum leak in the air controls, it will be more noticeable with a lower vaccum to start with.
The temperature control is a separate function, and is electrical.
Where the air goes is driven by vaccum from the engine.
With little to no vaccum, the default position for the air is the defrost.

Turns out that the vaccuum issue was at the rear AC switch selector on the front heater control. Replaced and works great. Thanks for the help!!!!
