A motor has to spin fast enough to create a voltage so the motor must spin for quite some tme and then free spin to create the electrical signal. Spinning only a 1/2 turn will not create an electtrical signal that will be recognize by the DME.

If he could unclip the front grille in front of the fan I would do that and see if the fan spin freely by hand. Could be the fan bearings are shot.
