HI,
I am sorry that you have not been helped yet. I just came online and saw your question
I have run into a few of these and the problem is a faulty circuit board inside the climate control unit. The only solution is as you suspected, replace the climate control unit.
If you need directions to replace it, let me know and I can upload directions
