I'm finally done with the entire install... I just recently finished re-wiring the pushbutton control unit in place of the rotary switch that came with the evap/bower kit.
I wired 6 relays to the CCU so I can now control the ac through the buttons.
the 3 fan speed buttons now function as 1,2,3 fan speeds. 3 more buttons are used for off, econ, normal modes. It involved hacking the CCU pcb.
Cleaned everything inside the CCU now the markings are brandnew bright.
