Cooling Fan Logic

PCM will energize cooling fan relay when an A/C request signal is received from A/C switch, or when coolant temperature is greater than 223°F (106°C). Fan will operate for 180 seconds after A/C request signal is canceled. PCM will de-energize cooling fan relay when vehicle speed is greater than 70 MPH for 180 seconds. Cooling fan relay is located in underhood junction block.
