2007-2009 Nissan Quest Windshield: Diagnosing Noises, Cracks, and Leaks

Symptoms of Windshield Failure

While some signs of a bad windshield are obvious, others can be subtle or misleading. Knowing what to look for can save you from a misdiagnosis.

Obvious Damage: Cracks, Chips, and Scratches

The most common symptom is visible damage. A small rock chip can quickly spread into a large crack, especially with temperature changes or vehicle vibrations. Deep scratches, particularly in the driver's line of sight or within the wiper path, can cause dangerous glare at night or in bright sun. According to Nissan service guidelines, even a tiny scratch can create a weak point that develops into a stress crack over time.

Wind Noise or Water Leaks

A whistling or howling sound at highway speeds often points to a failing urethane seal around the windshield's edge. This allows air to penetrate the cabin. The same failed seal will also allow water to leak inside, typically showing up as dampness along the headliner, A-pillars, or dashboard. This can lead to mold, rust, and damage to sensitive electronics.

Popping or Rattling Noises from the Dash

Many Quest owners report a persistent popping, creaking, or rattling sound that seems to come from where the dashboard meets the bottom of the windshield. While it's easy to blame the windshield seal, this noise is very often caused by the black plastic cowl panel on the exterior of the vehicle rubbing against the glass. Before assuming you have a major windshield issue, try lubricating the point of contact between the plastic cowl and the glass as a diagnostic step.

Visual Distortion or Delamination

If you notice a milky or hazy appearance around the edges of the glass, this is a sign of delamination. The windshield is made of two layers of glass with a vinyl layer (PVB) in between. When moisture gets between these layers, the bond fails, creating bubbles or a hazy look. Wavy or distorted sections of the glass can also be a sign of a manufacturing defect.

Buying a Used 2007-2009 Nissan Quest Windshield

A used Original Equipment Manufacturer (OEM) windshield is often a smarter choice than a cheap aftermarket one. OEM glass guarantees a perfect fit, correct curvature, and the same acoustic and UV-filtering properties as the original. Aftermarket glass may have slight variations in thickness or shape that can lead to wind noise, leaks, or a poor fit. Here’s what to inspect before buying a recycled windshield.

1. Check for Scratches and Pitting

Run your hand over the entire surface. Pay close attention to the area cleared by the wipers. Minor surface scratches might be acceptable, but anything you can feel with your fingernail could cause glare. Use a bright light to inspect for pitting from sand and small road debris, which can impair visibility in direct sunlight.

2. Inspect for Chips and Cracks

Examine the entire surface for rock chips, even small ones. Pay special attention to the edges, as chips here are more likely to spread. A crack of any size means the windshield is unusable. Nissan service documents note that cracks often start from a tiny, hard-to-see scratch or impact point.

3. Look for Delamination

Check the black border (called the 'frit') and all edges for any signs of a milky, hazy, or bubbly appearance. This indicates the vinyl layer is separating from the glass, a failure that cannot be repaired and will only get worse.

4. Verify the Part Number and Markings

Look for the manufacturer's stamp on the corner of the glass. An OEM windshield will have the Nissan logo. Cross-reference the part number if possible. The primary OEM part number for this generation is 72700-ZM70B, which supersedes older numbers like 72700-ZM70A and 72700-5Z000.

5. Examine the Rearview Mirror Mount

Ensure the metal bracket for the rearview mirror is securely bonded to the glass. This is not a part that can be easily re-glued. If the bracket is loose, damaged, or missing, do not buy the windshield.

Known Issues, Recalls, and TSBs

While there are no recalls specifically for the windshield glass on the 2007-2009 Quest, several related items are important for owners to know.

Technical Service Bulletins (TSBs)

• NTB17-019H / Windshield Cracking: Nissan has issued guidelines for dealerships to determine if a windshield crack is due to a manufacturing defect or outside influence like a rock chip or scratch. This bulletin acknowledges that issues like distortion, bubbles, and stress cracks can be warranty issues if no impact point is found.
• Cowl Panel Noise: As mentioned in the symptoms section, a common source of noise is the plastic cowl rubbing on the glass. Forum users have successfully resolved this by cleaning and lubricating the area where the plastic meets the windshield.

Vehicle Recalls

These recalls do not involve the windshield directly but are critical safety issues for this vehicle generation.

• NHTSA Recall 23V067000 (2008-2009 models): The resin emblem on the driver's side airbag cover can crack and detach during deployment, potentially becoming a projectile. Dealers will replace the airbag cover free of charge.
• NHTSA Recall 07V-248 (2007 models): A front suspension bolt may not have been properly tightened at the factory, which can cause a rattling noise and vibration. If it comes loose completely, it can affect steering control. This noise could be mistaken for a dash or windshield rattle.

Cost of Replacement

The cost to replace the windshield on a 2007-2009 Nissan Quest can vary significantly based on the type of glass used and labor rates in your area.
