The 2003-2006 Infiniti G35 Sedan, built on Nissan’s legendary FM (Front Midship) platform, completely redefined the luxury sport sedan segment in North America. Listening to the iconic, throaty growl of the naturally aspirated VQ35DE engine is an experience best enjoyed with the sunroof wide open. However, when that sunroof shatters due to a stray highway rock, suffers from a blown-out perimeter seal, or completely fails under extreme Canadian temperature fluctuations, the thrill of the drive is instantly compromised. As a Master Technician at AlexWindshield, I have seen firsthand how a compromised sunroof can lead to catastrophic water damage and ruin the pristine leather interior of your classic V35 chassis. You do not just need a quick fix; you need precision engineering and flawless execution.
Expert Infiniti G35 Sedan Sunroof Replacement in the GTA
Replacing the sunroof glass on a 2003-2006 Infiniti G35 Sedan is a highly technical procedure that requires a deep understanding of the vehicle's structural nuances. Unlike standard windshields, sunroof assemblies involve complex mechanical tracks, intricate drainage systems, and specialized weather-stripping. Over the years, the factory rubber seals on these early 2000s models degrade, harden, and crack. Furthermore, because sunroofs are made of tempered glass, an impact will cause the entire panel to explode into thousands of tiny, sharp pebbles.

The AlexWindshield A-Z Sunroof Replacement Process
As a senior technician, I adhere to a strict, uncompromising methodology to ensure your Infiniti G35 Sedan sunroof replacement is performed flawlessly. Because sunroof glass is tempered, a shattered panel creates a hazard similar to a broken rear window. Therefore, our process mirrors the stringent cleanup protocols used for side and back glass, combined with the precision sealing techniques used for fixed auto glass.
Step 1: Interior Protection and Shattered Glass Extraction
The very first step is securing the cabin. We drape heavy-duty, scratch-resistant protective covers over your G35's leather seats, center console, and dashboard. Because tempered sunroof glass explodes upon impact, vacuuming all broken glass shards from the vehicle's interior is an absolute mandatory step. We use high-powered industrial vacuums to extract every single piece of glass from the carpets, seat crevices, and floor mats. We also carefully inspect the rear deck and air vents to ensure no microscopic shards are left behind to cause injury or interior rattling.
Step 2: Accessing the Sunroof Assembly and Dropping the Headliner
To access the internal track mechanisms of the 2003-2006 Infiniti G35 Sedan, we must carefully lower the interior headliner. This involves meticulously removing the overhead map light console, the sun visors, the grab handles, and the A, B, and C pillar trims. We use specialized nylon non-marring pry tools to ensure the delicate, aging plastic clips of your classic Infiniti are not snapped or stressed during removal.
Step 3: Removal of the Damaged Glass and Frame
With the headliner lowered and the sunroof track exposed, we locate the mounting hardware. The G35 sunroof glass panel is secured to the sliding rails by specific Torx bolts. We carefully unbolt the remaining damaged frame from the lifting mechanism. If the glass is still intact but the seal has failed, we gently lift the old glass panel out of the roof cavity. We then extract any remaining shards of glass from the delicate mechanical tracks, as even a single piece of debris can cause the sunroof motor to bind and fail.
Step 4: Track Cleaning, Drain Tube Clearing, and Surface Prep
A new glass panel will not function properly in a dirty track. We utilize specialized automotive degreasers to clean the aluminum sliding rails, wiping away twenty years of dirt, grime, and hardened factory grease. Next, we locate the four sunroof drain tubes located at the corners of the sunroof cassette. Using low-pressure compressed air, we clear these drains to ensure rainwater flows properly down the A-pillars and C-pillars and out of the vehicle. Finally, the mating surfaces where the new glass seal will rest are rigorously cleaned with an alcohol-based surface prep solution.
Step 5: Primer Application and Weather-stripping Preparation
While the G35 sunroof panel is bolted into place, the perimeter of the glass relies on a thick, durable weather-stripping seal to keep wind and moisture out. In cases where the replacement glass requires assembly into the metal sub-frame, we apply an advanced glass primer to the edges of the panel. This primer acts as a chemical bonding agent, ensuring that the high-quality adhesive and rubber weather-stripping permanently bond to the glass, preventing any future wind noise or water intrusion.
Step 6: Installing the New Sunroof Glass with High-Quality Adhesive and Seals
We source only premium, OEM-equivalent auto glass that perfectly matches the precise factory curvature of the Infiniti G35 Sedan. The new glass panel is carefully lowered through the roof opening and set into the sliding tracks. Before tightening the Torx bolts, we must execute a critical alignment procedure. The glass must sit perfectly flush with the vehicle's roofline—if it is positioned even a millimeter too high, it will create severe wind whistling at highway speeds; too low, and it will pool water. Once perfectly aligned, the bolts are torqued to factory specifications, and specialized high-quality adhesive and sealing compounds are applied where necessary to reinforce the factory gaskets.
Step 7: Motor Calibration, Resetting, and Water Testing
The final technical step is calibrating the sunroof motor. The G35 features an anti-pinch safety system that must be re-taught its upper and lower limits after a glass replacement. We perform the factory reset procedure, cycling the glass through its full tilt and slide functions to ensure smooth, bind-free operation. Following successful calibration, we perform a rigorous water leak test, flooding the roof with water to verify that the new perimeter seals and the cleared drain tubes are functioning perfectly.
Why the Quality of Your Auto Glass Matters
For a high-performance vehicle like the 2003-2006 Infiniti G35, cutting corners on materials is never an option. Subpar aftermarket glass often suffers from visual distortion and poor acoustic insulation. At AlexWindshield, we utilize only industry-leading materials.
- Perfect Curvature Match: Ensuring the aerodynamics of your sports sedan remain untouched.
- Acoustic Dampening: High-grade glass maintains a quiet cabin, keeping the roar of the VQ35DE outside where it belongs.
- UV and Thermal Resistance: Premium factory tinting prevents interior fading and keeps the cabin cool during harsh GTA summers.
- Advanced Adhesives: We use rapid-curing, high-quality adhesive systems that guarantee a watertight seal that withstands extreme Canadian winters.
