I have had problems with my air conditioning. Sometimes it will blow cold air and than about 6 minutes it blows hot and than after about 10 minutes it is cold again. Any ideas on what is causing this?

Hello,

This sounds like the compressor clutch get hot and then stops working when it cools it starts again but to be sure here is a guide to check to see whats going on. When the AC is blowing hot look at the clutch of the compressor to see if it is turning.

My2002 F250 7.3 AC is intermittent. It runs strong for a while then starts blowing humid air. The air flow switches at will from defrost to panel to floor. Could my issue be in the dash controller?

Yep it could be but its more likely to be a blend door actuator or the vacuum feed line is broken/has a leak here is a guide to help you find the leak which normally is under the hood.
