Those codes are both HVAC codes. The 1411 is the temperature probe in the dash that tells the controller the interior temperature. The 1441 is the blend door in the case that controls air temperature. The second code won't stop the A/C from operating, the first one however will. Use your scan tool to access the HVAC system and see what it says the interior temperature is in the live data. I suspect you are going to see a much lower than actual temperature. Normally when a thermistor sensor fails open or the wiring fails so it opens, the temperature will read below zero, many actually read -40 below. The opposite is also true, if they short out the temperature will go up to 300 degrees or higher. In your case I suspect it has gone open circuit, and the A/C thinks it's -40 and won't turn on. You should be able to see that on the scan tool and because you have that tool you also have a very simple way to test. However, getting to the part itself takes a bit, it is behind the dash to the right of the steering column, behind the dash trim. To get to it you have to remove pretty much every piece of dash trim just to get the small cover next to the column off. That small grill next to the smart key or in the spot next to the column is where the sensor lives. Once you get to it testing is simple. Look at the room temperature, unplug the sensor connector, now use a piece of wire to short the 2 pins. If the wiring and the rest are okay, you will see the temp go way up to 200 or more. Replace the defective thermistor and it should eliminate the problem. If there is no change then you have an issue with the A/C amplifier module (control assembly).
The second code is likely a bad actuator, it is at the bottom of the HVAC case next to the blower motor, however if service info is correct you have to remove the HVAC unit to get to it.
