Compatible vehicles: ■ Mazda Atenza (GJ) CX-5 (KE) If the mirror doesn't retract even when the switch is turned on, there is a high possibility that the internal gear is defective. In the Atenza, the original door mirror gears are made of resin, and they break when the mirror is opened and closed after many years of use. I also experienced the left side mirror motor making a whirring sound and not moving, so I replaced the resin gear with a metal one. Recommended for those who want to replace it cheaply with DIY in the same situation. Shaft is not included. Please replace the metal gear.
