Causes for Broken Sunroof

There are so many reasons to break the sunroof of your vehicle. We have broken down some of the notable reasons. Regardless of the cause, you must understand how to fix a cracked sunroof.

  1. Misconfigured Windshield

A significant reason for your nightmare is a misconfigured windshield. We use windshields to protect the sunroof from powerful airflow or maintain minimal airflow at the top of the roof. But if we configure it the wrong way, it will cause a broken sunroof. 

Extreme pressure is created on the roof because air flows the wrong way. When the sunroof reaches a critical point of stress, it causes cracks and shatters. No matter how strong that sunroof is, a misconfigured windshield can cause a big disaster. 

  1. Cheap Product Sunroof

Many of us go with cheap products to save some money. Ultimately, you will get nothing but messing up with your car. Cheap products last only a short time. They are also built with weak structures. 

A cheap sunroof is just nothing but a showoff. It is just a massive waste of money. 

  1. Mechanical Malfunction 

You know, a full sunroof is dependent on a single motor. That motor controls the ON/OFF process. If that motor is jammed or misoperated, it will cause the sunroof to shatter. Besides, a motor malfunction can gradually weaken the glass. 

Many of us are so careless. We don’t check our mechanical motor or sunroof. Consequently, accidents take place. 

  1. Electrical Malfunction 

Due to careless charging management, almost 25% of users face accidents.

It seems pretty shocking, but it is a significant fact. Due to the high voltage flow during charging or lighting, the sunroof can be shattered. Excessive electrical flow makes the glass particles unstable. So, it starts to weaken.

Yep, you can get a temporary solution by replacing the sunroof with plexiglass. With some refurbished products, you can get a better solution for your car. Let’s look at these steps: 

  • Step 1: Fix the Porting Spot

At the very end of the break, drill a tiny hole with a delicate opening. Nevertheless, the entire windshield is widened when you drill the tiny opening at the farthest point of your scope. 

This will keep the break from spreading further down the windscreen. However, the introduction ought to be sufficiently small to adjust the brake arm but not large enough to break the windshield.

  • Step 2: Filled With Plexiglass

There are many ways to clean a character, but one of the easiest is to use a degreaser to wipe down the area before you begin your repairs. Once you have cleaned the surface, you can repair the material.
