Air conditioning blows out hot air on drivers side but cold air on passenger side. Any ideas on the cause?

If the air is cool in pass. side and warm on driver's side, you might just be low on refrigerant. But if it's cold on pass. side and hot on drivers side, you probably have an blend door actuator problem of temp sensor problem.

I recently got this problem on my Armada 2008. stephend103, your answer is ambiguous, can you try again please?

If you are running the a/c when it is hot outside, and there is a small difference between the temperature of the air on the driver side versus the passenger side, it could be due to low refrigerant. But since it is winter, and I assume you are running the heat, your problem is going to lie in the air distribution section of the HVAC system (i.e. behind the dash). Most likely a temperature blend door actuator is not working. This could be caused by a bad actuator, or a bad inside temperature sensor, or even a bad HVAC control head.

I have a 2010 platinum edition Armada I have noticed when I turn on the heater the driver side blows cold air the rest of the car blows warm the 2 Little center vents in the middle row blow cold as well what’s The issue in my vehicle please help
