I just removed the unit and have it totally disassembled. I think!?

Does the black plastic case which holds the boards come apart?

I think, from the thread, that I just solder the ones that look brown or loose. At first sight, everything is ok so I'm wondering if this will fix my CCU.(replaced my ignition switch because the CC goes off and on when it wants to.)

I'll solder what I think is bad and put it back together.
One more thing. The 'AUTO' button falls out. I don't really see anything holding it in except a small ridge on the bottom of the button?
