The cause of freezing and cracking of car mirror lenses in winter

The winter in the north is cold, and when the left side mirror is manually folded, the mirror bracket is broken. The right side side mirror lens was frozen out of cracks, and the manufacturer was requested to replace the left side side mirror assembly and the right side mirror lens. Note: The left side mirror is not damaged by force, and the damage occurs when it is gently folded within the range of activity allowed by the manufacturer, which is a serious quality problem. The right lens is naturally frozen and cracked in cold weather.

We would like to remind you that not all car mirror lenses are broken by cold weather, so what are the reasons for the breakage?

1. In the cold winter season, the weather freezes and damages the lenses of the car rearview mirror;

2. After the rupture of the rearview mirror, you see if it is thought that the operation is caused, and at the end of the year, the thief's action is doubly frequent;

3. Maybe it was hitting something or rubbing it with someone else's car.

Please analyze the above situation and draw conclusions, don't see the rearview mirror cracked and say that it is frozen, and the probability of being frozen is not as big as you think.
