www.m3 spiegel.de, que ahora tiene otra pag me ha contestado a la siguiente queja "oye hijos de p*** vibran los cristales" Me han contestado con mas educacion y me han dicho lo siguiente, muy interesante!! your problem with vibrations is mostly the problem with the painting.the trinage plate from the mirrors where you fix on the car must be painted inside correctly. There are 2 srcews and one hook. When the mirror is not correct painted inside the plate the hook has 1mm site and the complete mirror has vibrations. Rebuild the mirror, put off the 2 screws inside the metal triangle. Then you can take off the mirror motor and the hinge. Then paint inside metal triangle and put all parts together. Then you dont have vibration problems. we know your problem and every time is no correct painting inside the reason for vibrations.
