What are the Reasons for the Spreading of the Windshield Crack?

The main reason for the spreading of the crack is temperature. Extremely hot and cold temperatures can be included. The heat of the sunlight on a sunny day will directly hit the windshield crack. If you park the vehicle outside for several hours, the sunlight expands the cracked position.

As a result of the expansion, the relevant crack may be spread more than the last time. And also, the air conditioning can be affected by the spreading. If you turn the air conditioning on, the car that is parked under the sunlight may spread the crack.

Next is the bumpy rides. When the car is riding on roads with many bumps, the crack may spread. The sudden path hole on the road also affects this. This is an extra vibration for the car. Due to that, the cracks may worsen. The third one is the poor installation.

When the mechanic installs the windshield incorrectly, the edges will not align perfectly. When riding on the road, there is a pressure of the wind and the force due to acceleration. Due to these reasons, cracks may spread. Choose an experienced mechanic when working with car faults.
