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!
