A Cracked or Improperly Installed Windshield Is Dangerous

What Is as Important to Automotive Safety as Your Vehicle's Anti-Lock Brakes, Safety Belts, and Air Bags? The Windshield.

Some windshield damage may not be noticed immediately. That's why it's important to regularly check your windshield for any problems. In the past, having windshields cleaned and checked was part of the service provided at service stations.

Today, the responsibility for windshield maintenance rests with each driver. The good news is that it's easy. Use the following steps to inspect your windshield, or seek the assistance of a certified technician:

  • Check the entire windshield, inside and out, for chips and cracks. Minor chips and very small cracks may be repairable, provided they are outside the driver's primary line of sight. Many insurance companies will waive the deductible on such repairs. However, any significant cracks or damage will require windshield replacement.
  • Check around the edge of the glass for damage to the surrounding body work. Any problems that affect the seal of the glass to the body can weaken structural integrity and should be repaired.
  • Check the windshield wipers to make sure the rubber blades are soft and pliable. Hard, brittle, or damaged blades can break and allow the metal wiper arm to scratch the glass.

Windshield Repair

There's nothing more frustrating than having a flying object, perhaps thrown up by the vehicle in front of you, hit your windshield. You may have the option of getting a repair instead of replacing the entire windshield if the damage is small and not at a critical point on the glass.

Windshield Replacement

When the damage is more than a crack repair can handle, auto glass replacement is the step to take. It is important to your safety and that of your passengers to have the glass replaced quickly and proficiently when there is extensive damage.

Recently, General Motors Corporation issued a recall on the glass used in their 2007 Chevrolet Equinox and Pontiac Torrent models. Reportedly, an incorrect primer may have been used when the windshields were originally installed at the factory. That same primer also may have been applied to the liftgate glass and the stationary sidelites.

Don't Put Your Safety at Risk

Did you know the windshield of your automobile is a safety device, like air bags and safety belts? It's true. Besides its obvious role of protecting occupants from wind, water, and debris, the windshield can help save your life, and the lives of your passengers, by ensuring you are not thrown from the vehicle in a collision. Windshields also play a critical role in front passenger airbag deployment on many cars. And, the windshield (and rear window) helps support the roof of the vehicle in a rollover so you and your passengers will not be crushed.

Regular Check-Ups Keep You Safe

Some windshield damage may not be noticed immediately. That's why it's important to regularly check your windshield, and all vehicle glass, for any problems. Use the following steps to inspect your windshield, or seek the assistance of a certified technician: · Check the entire windshield, inside and out, for chips and cracks. Minor chips and very small cracks may be repairable, provided they are outside the driver's primary line of sight. Any significant cracks or damage will require windshield replacement.

  • Check around the edge of the glass for damage to the surrounding body work. Any problems that affect the seal of the glass to the body can weaken structural integrity and should be repaired.
  • Check the windshield wipers to make sure the rubber blades are soft and pliable. Hard, brittle, or damaged blades can break and allow the metal wiper arm to scratch the glass.

Avoid Cut-Rate Auto Glass Replacement

If you determine that your windshield needs to be replaced, remember & you get what you pay for. The lowest possible price should not be a primary consideration when having a windshield replaced. Instead, look for a top-quality professional installation that will maintain the structural integrity and other safety features built into your vehicle at the factory. Many auto glass companies perform quality windshield repair and replacement. Unfortunately, there are also some that do not. If you know the right questions to ask, you can greatly increase your odds of obtaining a professional installation. Ask the service providers if they:

  • Have National Glass Association (NGA) certified technicians
  • Endorse and adhere to the Auto Glass Replacement Safety Standard (AGRSS)
  • Use OEM (Original Equipment Manufacturer) quality glass for replacement
  • Use the manufacturers recommended urethane adhesives
  • During the installation, watch to see if the technician:
  • Checks for a front passenger side air bag and, if present, uses a urethane rated for that type of installation
  • Removes the old windshield sealant, leaving approximately 1/16-inch of bonding surface
  • Wears latex or nitrile gloves to avoid contaminating the bonding surfaces
  • Cleans and primes both the glass and vehicle body in those areas where the urethane adhesive makes contact. After the installation is complete, inspect the work carefully. You don't need to be an auto glass expert to identify some signs of improper installation. From outside the vehicle:
  • Check to see if the windshield is perfectly centered on the car. The distance between the left side and the right side of the windshield and the auto body should be the same.
  • Check to make sure the glass is flush with the vehicle body.
  • Inspect the molding around the circumference of the windshield. There should be no visible gaps, and the molding should lie flat and even — not look like a roller coaster.

Remember, the windshield does more than just keep out wind, water, and bugs; it helps keep you and your passengers safe in a collision.
