I had the same truck with the same problem, and I also get alot of warranty claims with this same complaint and the GM guys say it is very common for these temp mode door actuators to go bad. There is one on the left side and one on the right side, and it sounds like the left side actuator is intermittently shorting. The left side temp mode door actuator is bad.

I once had a Ford Maverick, a Toyota Camray and a Jeep Grand Cherokee. The same thing happened in each of these vehicles and I have learned that each time It does the first thing I will check is the condensation drain tube. Every A/C system has one; the location differs depending on the vehicle, but, when they get clogged the water will not drain and once the system is filled with water the system will not cool. The only reason you have air at first is due to the fact that some of the water in the container or condensation collection tank has evaporated and once it fills again the cool air stops and only blows warm air. usually there is a sensor on the out side of the collection tank which determines when the unit should stop blowing cool air and once the tank fills with cold water the sensor determines that it needs to shut down than when the water in the tank warms up again the sensor will than determine to blow cold air again. Drain the condensation tanks; in other words, check and make sure the system is draining. Other than that each unit has a sensor at the compressor; having dual systems you may have two sensors and one of them is faulting. Turning the truck off and back on resets the sensor until it warms up and than it shuts down or faults again. Good luck, I know how frustrating A/C systems can be; especially on those hot days. Hope I resolved your question. Generally vehicles with only one system for A/C will have the same problem. I once had a Ford Maverick, a Toyota Camray and a Jeep Grand Cherokee.
