I have a 2000 model 7.3 power stroke and the hotter my engine gets it starts to blow hot air like the heater is on when I'm. Running my a/c. Any reason you can think of why it does that?

Check for a vacuum leak first then check items 1-9-11 inpic they control doors that control heat/cool they may be loosing vacuum and not staying closed open etc.
