i bought a 2008 s6 with 120k on it damaged in the front, had to replace the rad support condenser and radiator, the cooling fans were intact but there housing was busted, so i just replaced the housing. so now i have it all back together and the fans do not kick on, even if i turn the ac on, but the ac compressor does kick in. my question is does any one know what is required to turn the fans on? both plugs have two big wires and two small wires going to them. i would like to see if i can manuly make them go on before ordering new ones.
