INSPECTION PROCEDURE 5: Radiator Fan does not Operate





[2.0L ENGINE]





[2.4L ENGINE]






CIRCUIT OPERATION
^ The fan control module is powered from fusible link number 2.
^ The ECM [M/T] or PCM [A/T] judges the required revolution speed of radiator fan motor and condenser fan motor using the input signals transmitted from A/C switch, automatic compressor controller, vehicle speed sensor and engine coolant temperature sensor. The ECM [M/T] or PCM [A/T] activates the fan control module to drive the radiator fan motor and condenser fan motor.

TECHNICAL DESCRIPTION
The cause could be a malfunction of the radiator fan motor or an open circuit between the fan control module and the radiator fan motor.

TROUBLESHOOTING HINTS
^ Malfunction of radiator fan motor
^ Malfunction of fan control module
