When the fan only works at level 4, the fault lies with the resistor.

Model: Citroen Berlingo MK 2 - Years 2008-2018
Part: Blower motor

As we can see in this video, when the fan only works at maximum speed, it is the classic symptom of a burned resistor. In fact, this component is responsible for reducing the voltage that reaches the fan motor, in order to make it spin at lower speeds. If one or more of its internal resistors burn out, the corresponding speeds stop working, while the maximum speed bypasses the resistor and sends full voltage to the motor. It can be easily found on E-Bay with the code 145383755524 at a price of 12.09 euros, with free delivery. It is located in the right footwell in an accessible position.

How to Open the Bonnet on the Lancia Y

To open the bonnet on this vehicle, follow these simple instructions: first, open the driver's door and locate the lever positioned just below the dashboard, marked with an image of the vehicle with the bonnet open. Pull this lever towards you until you hear a "click" indicating the bonnet is released. Next, exit the cabin and stand in front of the bonnet to disengage the safety catch and complete the opening. To do this, slightly lift the bonnet, locate the yellow lever underneath, and pull it to the left to fully release and open the bonnet.
