Circuit Operation

WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.

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 < M/T >, output shaft speed sensor < A/T > 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.
