Does A/C turn off automatically climbing hills ? Ford F53

I used to have a van (dodge ram van) that had a similar issue. I could change where the air came out (defrost, dash, or feet) by backing of the gas and then stepping on it. When going up a hill it would switch and all I had to do was the above routine until it went back to the vent I wanted. Kind of funny, kind of annoying, not worth the hassle to fix.
