What is your question?
When I go up a hill & accelerate ,the a/c blower stops. When it levels off ,the blower comes back on. Sounds like a small door closing under the dash near the floor.

Are you sure that the blower is actually stopping, and that it isn't changing settings? Generally, what happens is that you will have the blower set to the dash vents, but when you increase engine load it will switch to the windshield defroster. Check to see if that is what is happening on your car. If it is, then most likely you have a vacuum leak in in the system that actuates the vacuum motors for the blend doors. This kind of work can get pricey, depending on where the leak is.
I BELIEVE ITS CHANGING TO DEFROST CK FOR VAC LEAKS UNDER HOOD AND POSS DASH
