Symptoms: My truck's A/C works great for about 20 minutes after initial start up. It goes hot. I can place the truck in neutral while still rolling and shut off the engine and restart it to reset the A/C. It will blow cold for about 7 minutes and lose the cool again. I've tried re-calibrating the actuators. I've set the fan to highest setting and it will hold a colder blow while driving for about 25 minutes before losing the cool. I replaced the A/C High Pressure switch. The A/C blows great with cold air if it remains parked and idle while running. With all the cold air that comes out when it's working, and I mean cold, I don't suspect any low Freon issues because when it's working, it's working great. Could this be an actuator issue? A control panel issue on/behind the dash? Any help would be greatly appreciated!
