Hey all, I have a 2011 Armada Platinum and recently the rear climate control is always blowing high. Both front and rear controls work to adjust temp but neither knob will affect the blower whether it’s set to off or anywhere in between, if the key is turned, the rear only is blowing on the highest setting. Super hard to control the temp for the kiddos in the back when it’s either too hot of too cold. We live in Michigan so these winter mornings start off with a cold blast until the vehicle warms up lol. Any help as to what needs to be replaced would be greatly appreciated! Temp and zone buttons work. Thanks in advance!

Without a service manual I can only guess. What happens if you unplug the rear climate controls?

Hi, a few things. I am new here so greetings. I am having the same problem I have searched here for rear climate control stuck on high. Information with the search bar I have not gotten a good answer as to what, where and how to replace what needs to be replaced. It the rear not the front. Thanks for any advice and help in advance!

Now that you posted this I have an issue where I can’t control the rear from the rear controls only the front.. setting it to “R” does nothing.

I had the same issue on my 2011. I just replaced the rear blower motor resistor and for some reason it only works some of the time. It’s not stuck on high anymore tho...not sure if that’s better or worse? Just got done a few minutes ago so I’m going to give it a few days and monitor it.

This is the link that shows you how to get to the rear blower Motor resistor, he’s just replacing the actuator instead.

How do I go about unplugging the rear climate controls?
