No expert here. Are your air ducts leaking. Sucking in hot air in the summer and cold air in the winter? Just a guess.

Sounds like your air blend door system is on the fritz.
Check your return line from the evaporator back to the A/C compressor if the line gets cold (should probably sweat unless you live in the desert) and you don't get cold in the truck then clearly you have air going the wrong place. Probably a vent door not working properly.
On the other hand, if the line doesn't get cold, forget about the air and get your freon pressures checked. It's harder to condense at higher temperature when you have a low charge of Freon. This might be indicated by your comment that it works at 80.
