Electric Cooling Fans

NOTE: For specific electric cooling fan testing, see ELECTRIC COOLING FAN CIRCUIT DIAGNOSIS test under CIRCUIT DIAGNOSIS TESTS. For component locations, see COMPONENT LOCATION . For terminal/wire color ID, see the WIRING DIAGRAMS article

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. For cooling fan relay location, see COOLING FAN RELAY LOCATION table.

To help save diagnostic time, ALWAYS check for blown fuses or fusible links before proceeding with any testing. If fuses are blown, locate and repair short circuit before replacing fuses. Ensure all related relay and wire harness connections are clean and tight. Repair as necessary. For component location, and terminal and wire color identification, see the ENGINE COOLING FAN article in the ENGINE COOLING section.

WARNING: Vehicles may be equipped with a PCM using an Electronically Erasable Programmable Read Only Memory (EEPROM). When replacing PCM, the new PCM must be programmed.
