Inspection Procedure 6

INSPECTION PROCEDURE 6: Condenser Fan does not Operate [3.8L Engine]

Radiator Fan and Condenser Fan Drive Circuit

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 condenser fan motor or fan control module.

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