Engine fully warmed up, temp gauge sitting at 12 o'clock, idling in traffic or in the driveway with the hood open, you can hear\see it.
If the fan don't run in low speed, there are 3 possibilities.
1. High speed relay normally closed contact is bad
2. Resistor mounted in the fan is open
3. The slow speed relay control circuit is not closing, from either the absence of ecu input or from a bad radiator temp switch
