Climate control panel not working

The car listed above is an Opa. I have had this car for 9 months.
The climate control panel has always remained the same as it is in the photo uploaded.
I cannot change any settings.
The fuses to the blower motor and to the control panel are fine.
The blower motor is Fine as I have taken it out and ran the motor off the battery as a test.
Now the only button that works on the panel is the hazard button.
The hazard button is a part of the circuit board that powers all of the other buttons on this panel except for the clock which is separate.
I have taken the panel out and opened it to see if I could find any burnt circuit wields (etc, ) but nothing at all.

I hope you can help as my situation is dire.
All windows fog over in the rain and in New Zealand it is the beginning of Winter.
As you can see on the passenger floor there is cat litter to help soak up the moister that remains ever present in my vehicle.
