All other buttons work on rear A/C control panel, I just can't turn the A/C temperature down.

If the panel lights up but there is no control over the temperature it is usually the control module, unless the temperature inductor goes down, but the temperature stays the same then it will be the rear temperature blend door actuator. Here is how you can change out the rear control module in the diagrams below. Check out the diagrams (below). Please let us know what happens.

I was thinking I'd have to replace that. Everything else works fine. So, it's called the rear control module?
