When i start the truck, the a/c blows good from the dash vents. and I can change it to the floor or to the top vents,etc. but after a while, the doors close, the air is still cold and the fan control still works. but the front dash vents close. there is no time on this, sometimes it works for an hour or better, sometimes the doors close before i pull out of the parking lot. also, when this happens, i cant change the mode anymore, to floor or anything else. I still have cold air and fan control. After looking at several videos, i believe it is either the mode door actuator, or the fan resistor. I cant seem to locate the mode door actuator
