How is the Cooling Fan Assembly controlled and what steps should be taken if it is not functioning properly on 2004 Volvo V40?

The engine management ECU regulates the cooling fan through the relay based on the information of the coolant temperature sensor. If the fan does not operate, look at the relay or motor. For repairs, disconnect the battery, wiring, and hoses and take specific steps for non-turbos or turbo repairs to access and replace the fan assembly.
