Electric Cooling Fan Control

WARNING: This page is about a different car, the 1998 GMC Forward Control and 1998 Chevrolet Forward Control. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: For electric cooling fan circuit testing, see ELECTRIC COOLING FAN article in ENGINE COOLING section.

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. Some RWD vans are equipped with an auxiliary electric cooling fan.
