AC only works on Hi

2008 F350 XL standard cab. My ac blows cold and strong but only does so with the fan set to 3 and 4. 1 and 2 don't work. This is when set to Max AC.

With the controls set to just vent, all fan speeds work, but work best when the truck is moving and nothing happens with the recirculation button on. Any ideas?
