This is a common problem with these Jeeps. There is a plastic piece inside the thermostat control knob on each side (dual zone), which can break after time. It will not feel like it is broken when you turn it, but it is no longer changing the temperature and it will be stuck on the last setting it was on before it broke. One of your control knobs has this problem. It is a $25-$30 part that can be installed by most A/c repair shops or a Jeep dealership for a lot more.
