If you just put your fingers only on screen, you can try to find problem in that place if you know what i mean. Clime ecu is in clime button section, and it wires all over the place, some to fuse ecu, some don't know, some in radio, it is hard to find all the ends. Clime ecu is rock solid, i put low hopes that is broken inside after punch. Check the radio, re-plug it.I'm not so sure. There are two signals which go from climate control unit to radio unit. One is DISP CLK and AC SO. I do not know what they do...
E4*RED*Climate control unit (DISP CLK)*
E5*YEL*Climate control unit (AC SO)*
