Mercedes G Class rear window price, by year
Pricing varies based on your specific variant's features — whether alarm wire circuitry is integrated, solar-control coating is present, and privacy tinting on rear quarter windows. Variants with additional hardware or integrated systems typically carry slightly higher costs due to the additional parts specification and specialist sourcing.

Our parts check team verifies the exact specification and confirms all hardware and wiring details.

On fitting day, your specialist removes the shattered rear glass and fits your replacement — typically 30–60 minutes of the fitter's time, with shard cleanup included.
- 5
A shattered rear window means glass fragments may lodge in places the fitter can't easily access on the day — we recommend a professional valet afterwards for thorough interior detailing.
- 6
Your replacement glass comes with a two-year warranty covering workmanship and glass quality.

Mobile fitting or workshop visit for your G Class?
G-Class rear-window replacement can typically be arranged at your home or a workshop location — your local specialist will confirm the best option based on their equipment and your location when you're matched.
Since rear-window jobs don't involve ADAS calibration, there's no technical reason to require a workshop visit unless you prefer one. Mobile fitting at your address is the standard approach, allowing your specialist to complete the job with minimal disruption.
We confirm the specific answer for your vehicle when you book.

Heated Rear Windscreen4
2018–2026On the Mercedes G Class: fitted on every one of the 4 rear window variants we list; model years 2018–2026.
Heated rear windscreen with integrated wires clears mist and ice when you switch on the demister.
What it means
A heated rear windscreen contains fine heating wires embedded within the glass. When you activate the rear demister, an electrical current passes through these wires, warming the glass and melting ice or condensation. This feature is particularly useful in cold or damp weather, improving rear visibility quickly. The heating grid is integral to the glass and connected to your vehicle's electrical circuit via connectors at the base of the windscreen.
How to tell
Look at the rear windscreen from inside the vehicle — you will see a fine grid of horizontal lines across the glass, typically bronze or copper in colour. On the dashboard or steering wheel stalk, there will be a dedicated rear-demist button, usually marked with a windscreen symbol and heating lines. If in doubt, ask your vehicle's service centre or consult your handbook.
Replacement impact
Replacement rear windscreens with heated grids are widely available as original-equipment aftermarket or dealership parts. The new glass must include the factory heating grid and electrical connectors intact. The technician will reconnect the heating circuit to your vehicle's rear-demist switch. Heated rear windscreens are bonded glass, so adhesive cure time applies; drive-away time will be confirmed by the fitter on the day.
Green2
2018–2026On the Mercedes G Class: fitted on 2 of the 4 rear window variants we list (50%); model years 2018–2026.
What it means
A subtle green tint present in roughly 90% of all automotive glass — it's hard to see at a glance but is part of the factory specification for your G-Class rear window.
On your Mercedes G Class
Present on select G-Class variants as a factory specification; confirmed during the parts check against your exact model and year.
Grey Privacy2
2018–2026On the Mercedes G Class: fitted on 2 of the 4 rear window variants we list (50%); model years 2018–2026.
Dark grey tint on rear windows provides privacy and reduces interior heat and glare.
What it means
Dark grey tint, formally known as privacy glass, is a factory-applied tint created through a deep-dipping process during glass manufacture. The pigment is infused into the inner surface of the glass, darkening the rear windows (and sometimes rear doors) significantly more than the front. This reduces heat transmission, minimises glare, and obscures the interior from outside view. It's standard on the rear half of many modern vehicles.
How to tell
Compare the rear side windows and rear window (backlight) to the front side windows — the rear glass will be noticeably darker. Check your vehicle documents or ask your dealership service centre if you're unsure whether your car left the factory with privacy glass.
Replacement impact
Dark grey tinted glass must be sourced from the Original Equipment Equivalent (OEE) or dealership to ensure colour and transmission match your vehicle's existing rear glass. The tint is integral to the glass itself, not a surface coating, so aftermarket non-tinted glass will look visibly mismatched. Replacement does not require any calibration and follows standard bonded-glass cure times for rear windows.
Solar Control2
2018–2026On the Mercedes G Class: fitted on 2 of the 4 rear window variants we list (50%); model years 2018–2026.
What it means
A special coating that absorbs the sun's infrared rays, helping to reduce interior heat gain and improve climate control efficiency.
On your Mercedes G Class
Typically fitted on higher-specification G-Class trims and premium variants; confirmed in your parts check as part of your vehicle's original spec.
About the Mercedes G Class
The Mercedes G-Class has been in continuous production since 1979, evolving through multiple generations. The current generation (W463A, launched 2018) features robust rear glass engineering with factory-fitted hardware and, on many variants, integrated alarm circuitry as part of the vehicle's security system.
Rear windows on the G-Class are typically toughened glass — when shattered, they break into small fragments rather than long shards. Some higher-specification variants come with solar-control coatings to reduce interior heat gain, whilst privacy-tinted rear quarter windows remain available on select trim levels as a factory option.
