A/C gets hot at highway speeds, but cool when idling.

Hello, i have a 1998 ford explorer eddie buarer, v-6. My issue is, that when i am driving my a/c starts blowing warm air. When it is just idling it blows cool air. I have changed the thermostant, actuator, orficie tube, fan clutch. I have had the system flushed and evac 2 times. I remember, 2 years ago, i had some electrical part replaced for my eatc display to work, also during a time, it stored in my garage, it sat for almost a 1.5 years. No one cut my a/c on while i was gone and when i started driving again. My a/c hose busted on me. What could be causing this issue. Thanks
