Radio works and AC works, but you cannot change stations or change the AC temperature. What can I do to make controls on center console work. I have checked fuses, both inside and under hood, all or OK. Steering wheel radio controls work. Light showing AC is on do not work.

The circuit is very complicated for steering and console controls as they do share some circuit components. In most cases everything ends up running through the radio. So, that is one place to look.
More than likely it is going to be a circuit board level test and you have to have special fixtures, in most cases, to test them. There is a central control unit under the dash that has its harness going into and out of the stereo. You could start by wiggling that around to see if you have a loose wire. The other thing to do is to pull the trouble codes. Any Advance Auto or Auto Zone will do this for free.
