Very often, the Chevrolet Avo 2nd generation (T300) vehicle is out of service with mirror adjustment. In this case, the reason should be first found in the fuse that is responsible for this function. The mirror adjustment fuse in the Chevrolet Aveo is located in the subunit block (the block itself is located on the right side of the subsurface and is covered by the cover on the latches).
The safety of the mirrors in Chevrolet Aveo is the safety of the mirror #13 or No. 28 (for the exterior rear view mirror). It is necessary to check its integrity and to replace it with a new one if necessary (the center of the unit has several safety devices No16-22 on the diagram).
