The second link is about Air bag and AC system. It talks about how and what to do if a given issue arises from the AC but not talking about the issue that you're having. Most of what is written is about the compressor and it's general function.
Reading some of the forums out there on the subject, this seems to be a common problem for your car though no one really nailed down a fix. Some have had issue with micro motors [i think this is the motors that actuates the gates inside the system to distribute cold/hot air. I believe they were also talking about a duel climate control system and a temperature sensor. The temp sensor must be inside the cabin, most likely near the air passage if your car is equipped with a duel climate control set up. The two most common things that were discussed was the temp sensor and the micro motors.
That being said, what I recommend for you is to try and diagnose the problem on your own. Checking the micro motors should be fairly easy [relatively speaking]. You should be able to see and make sure that the gears are not stripped and the motors are functioning properly, the gates are operational etc... If you have temp sensors, try and see if you can switch the left and right one to see if it makes a difference [if the sensors can be switched]. If it does, then you know one of the sensors is bad.
