OK thanks guys. My car had the fusein the pannel itook itout and wired up a seperate one. I took out the ccu and can't visually find anything.there is always powe and ground at the resistor terminals ifijump power to the small yellow wire the fan works. Even when the blower doesn't work when I cycle the ccu buttons I heart a relay click under the dash somewhere. But I can't find it. Mabyi should just put a potentiometer in the dash hookero the yellow wireon resistor forfan speed controll.
