How to make the Mercedes fan motor work again

Model: Mercedes Classe A W176 - Years 2012-2018
Part: Blower motor

In this video we can see how to make the engine fan motor of our Mercedes work again: first of all we remove the battery cover, and we will be able to see inside the position of the fan and its motor, and check if it is spinning. If touching it doesn't work, and the fan motor doesn't work at any speed, we can go inside the cabin: in fact, these motors are usually located under the dashboard, or even under the glove compartment, and disconnect the 2-pin connection that goes to the fan motor. With a multimeter or a test light, make sure you have the 12 volts necessary for operation, and if you don't have them it means the motor is broken; but in most cases, simply touching it is enough to get it running again.
