I searched but to no avail. I need to know if the slim fan that comes with the CBRD radiator (or even stock for that matter) will / should work with the ac removed. I know it's not even the ac fan we're talking about but when I finished the install and tried to test the fan operation by pressing the ac button (still lights up) nothing happened. I thought the fan would simply spin in the wrong direction if I got the polarity switched but, like I said, nothing. Anyone know whats up?

 

i dont believe the fan is dependant on the ac alone. the fan control box affects it also...

if you want to test it, touch the wires to the battery....

i believe the black wire on fan goes on the outter pin on the ecu control box.
