What controls condenser fan on 2005Chevy equinox?

On a 2005 Chevy Equinox, the condenser fan is primarily controlled by the engine coolant temperature sensor and the engine control module (ECM). When the engine temperature rises above a certain threshold, the ECM activates the condenser fan to help cool the engine and maintain optimal operating temperatures. Additionally, the air conditioning system can also trigger the fan to operate when the A/C is engaged, ensuring efficient cooling.
