Is your AC blowing hot? Is your heat blowing cold? Before attempting more drastic measures, like replacing the AC refrigerant, or digging behind the dash to check the heater core, try some of these tips! It could be that the temperature control blend door is just stuck, or the actuator has failed. Check out this video to see how you can diagnose temperature control problems for yourself!

    Hi So I have a 2011 GMC Acadia and the driver side vent and 1st vent in the middle of the dash to the left is blowing out out air. If I replace the actuator under the dash will it fix this problem or would have to replace the passenger side as well? thanks.

    Great vid advice! Same problem in my truck and it was making the flap knocking sound when it was on 5. I turn it down to 4 or lower and no more flap knocking after years of doing this. Now, it is hot on one side when AC is on. Likely actuator like this video explained. Taking it to a shop tomorrow. Thank you.

    My passenger side and back seats were blowing hot air, drivers side was cold. I went through the glove box, unplugged the green wire. Plugged it back in and everything works great now. I didn’t have to replace anything. I have a 2014 Lincoln MKX.

    Good video - but from the title I was hoping you would tell us how to diagnose if a constant heat from both sides of the vehicle is either blend door OR temp sensor OR head unit. Seems like there might be a way with a multimeter to check head unit and sensors - was hoping to find that information.

    Hi, I have a 2002 GMC Yukon Xl 1500 with a digital heater/ AC control module. It only gives me heat at max setting, so I have 2 options: cold or very hot (nothing in between). I've replaced the actuator at the passenger side but without succes. What could be the problem ? Thanks.

    I have a question about my 99 accord v6 204k mi my heater will blow hot heat just fine and stay hot when really cold outside but when temp outside warms up heater wants to blow cold it’s full of coolant and tanks on max line changed my mode actuator cause had no selection over vents and no flow through 2 center vents it’s climate controled is this normal for this to blow cold when warm outside places say it could be a clogged heater core blows good n hot heat when cold outside

By the way the car is Silverado 2016 model thankyou in advance

    I have a '08 Mazda 2.0 car has been giving me hell with the ac. Blew 2 New compressors in 1 month. Finally took my car to an AC car repair and had the system replaced compressor, dryer, and expansion valve. Everything was going smooth for the first 3 days. 4th day driver side and middle vents started blowing hot and the pass side was freezing cold I am so annoyed at this point
