You want the dial to the setting at 3 o'clock, the wifi looking symbol. One lead on the black pin of the fan connector (body harness side, not the fan itself) and the other lead on clean bare metal or any visible ground connection point such as the ones screwed into the upper radiator core support right behind the headlamps. The thing should beep if there is no break in that wire. Keep in mind that if you ever use this function for any reason, the test must always be done on an unpowered or de-energized circuit, as the multimeter sends out an electric charge of its own down one lead and expects to see it return on the other, hence the beep indicating continuity. Here, you're only doing it on a ground connection so it's generally safe regardless of the situation. If you ever put it on a normally-powered circuit (one which is fused), you must remove power from it or the  entire car altogether, whichever is safer. If you don't follow this rule, you blow up the multimeter in some cases depending on how well it's designed and protected. The same goes for the ohm meter function which is one position above this diode checker function, the Omega symbol.</p></blockquote><p></p>
