I pulled out the climate control buttons and removed the circuit board. Now, get this as I pulled the radio out I thought I would check the to see if the fan started to work so I turned on the key. Sure enough it did. So I continued to pull out the the acc control unit. Then I turned the key on again just before I unplugged it. And then it didn't work. So I unplugged it and put it on the bench and started to take the board out. I noticed a hot spot by left bottom corner on the circuit board. It was a diode. I checked it and it was still good. So I resoldered the connections and reassembled it. It still doesn't work but I did for a second. Boggles me. I did also resolder the on and off buttons but they looked good to me.

Nope you can push any button and the thing stays in slow fan and heat is on. A|C does not work either. Recirc, does not work either.
I think I need a new push button control unit.... If I was working around it and it started to work. Something must be funny in there.
