    2012 F07 GT m Sport

    I have just replaced the final stage resister but still no response form the fan speed switch. Everything lights up but the fan is still not blowing. Does this part need coding or does anybody have any idea what I can check or test next?

    The blower regulator does not need coding. So you went to the trouble of replacing it but didn't check the blower motor? The blower motor itself only has two wires going to it. Power and ground. Hook some jumper wires to it directly and to a 12v source like a battery or the jump posts in the engine bay.
