1. A method for monitoring an actuator comprising a movable element, a guide for guiding the movable element and a motor for driving the movable element along the guide, the method comprising:
for each of the portions of the guide, obtaining an operating signal measured when the movable element travels along the guide portion in question, on each of several successive activations of the actuator;
for each of the guide portions, seeking wear of the actuator from the operating signals obtained for that guide portion; and
locating the wear on the guide or on the motor depending on the guide portions from which the wear is found.
