i spliced overide switch directly linked to the battery and it would ground through fans motor ground bypassing the controller completly. I checked that the a/c clutch was sending power to the controller. it checks good and i also changed power sources to a constant 12 volt source(domefuse). the controller still did not kick the fan on when the a/c was engaged. i'm suspecting the relay on the controller is not fuctioning correctly. <img src="/forums/images/graemlins/angry.gif" alt="" />
