Before replacing the electric fan, make sure it's working properly.
Check the fuses. To test the electric fan, apply power directly to it using additional wires.
In the images below, you can see that there are two wires connected to the electric fan.
Apply 12 volts to the red wire (positive) and negative to the black wire.
If the electric fan works, the fault must be sought either in the heater electronic control unit or in the heater control module.

On some models, the rod can be removed by taking out its retainer.
If there is no rod retainer, remove the electric fan as follows.
By turning the electric fan, ensure that the vacuum booster rod enters the fan housing.
After this, turn the electric fan, being careful not to damage the fan blades.
