Electric Cooling Fan Control (Light Trucks & Vans)
All FWD and some RWD vehicles use an electric cooling fan. The electric cooling fan is used for radiator and A/C condenser cooling. Cooling fan operates when A/C is on and when engine coolant temperature exceeds a specific value. One or more cooling fan relays may be used. See COOLING FAN RELAY LOCATION table. Some RWD trucks, vans and motorhomes are equipped with an auxiliary electric cooling fan. See WIRING DIAGRAMS .
