Why is my 2015 Holden Cruze's fan so loud?

Why does the fan in my 2015 Holden Cruze sound loud?

I’ll assume by 'in' you mean the fan that blows climate-controlled air into the cabin and not the fan that cools the radiator under the bonnet. Like anything else powered by an electric motor, these should be almost silent, although the sound of the actual air rushing through the trunking (heater plumbing) and out through the vents can usually be heard when the fan is running full blast.

The most common causes for this noise to change are a failed bearing in the motor which will also potentially affect its running speed, or something foreign caught in the fan’s blades (leaves and dross from parking under trees is a common cause of this).

Cleaning out the fan’s trunking and/or replacing the fan is the solution, but in some cases, this involves fairly major disassembly of the car’s dashboard and a huge labour bill.
