Hi people. As you all know, 88-91 Crx have two stock fans on the radiator to cool it off. My fans have the wires cable to the fan but it doesn't turn on. Do i need to connect it up to somewhere? I don't think it has power to the wires. Cause when i place a Double AA battery to the negative and the positive side. it turns on. But when i don't have the double AA batteries, it won't turn on. How can i connect this so that it work when the radiator is hot? . . . I tried hooking the negative to the negative wires on the battery of the car and the other blue wire to the positive battery of the car . . and this turns on the fan even when the car is OFF. LOL so can't do it that way. Any suggestion?

 

You are probably messing with the AC fan, which is for the AC condenser not the radiator so it works independently of the cooling system.
