Mercedes GL rear window price, by year
Rear-window pricing varies with generation and the presence of integrated electronics. Earlier models with basic heated glass are typically the most affordable. Later variants with antenna integration or privacy tinting carry higher costs due to the precision required in matching the electrical connections and ensuring the antenna print aligns correctly with your vehicle's receiver.

What to expect during your Mercedes GL rear window replacement
Replacing your GL-Class rear window is straightforward — most jobs complete in a single visit.
- 1
Start with a quick online quote: answer a few questions about your GL's year and trim, and we'll match you with the right replacement glass in under 60 seconds.
- 2
Our team runs a parts check to confirm the exact variant you need — including any antenna, privacy tint, or alarm wiring — so there's no surprise on fitting day.
- 3
You'll be matched with an approved fitter near you, available at a time that suits. Mobile fitting at your address is the standard option.
- 4
On the day, the fitter removes the shattered glass, clears accessible shards, and installs your matched replacement. A rear-window job typically takes 30–60 minutes of the fitter's time.
- 5
Because the rear window is toughened glass, there's no long cure time — your fitter will confirm the drive-away time before leaving.
- 6
We recommend a professional interior valet afterwards — small shards can work into places the fitter can't easily reach on the day.
Your replacement comes with a two-year warranty covering workmanship and glass quality.
Mobile fitting or workshop visit for your GL?
The Mercedes GL-Class (2005–2013) does not require ADAS calibration after rear-window replacement — this generation pre-dates windscreen-mounted driver-assistance systems. Mobile fitting at your address is the standard option for rear-window jobs.
If you prefer a workshop visit for any reason (weather, vehicle access, or peace of mind), your fitter can arrange that. Most jobs complete in one visit either way.

Antenna2
2005–2013On the Mercedes GL: fitted on every one of the 2 rear window variants we list; model years 2005–2013.
What it means
An aerial laminated into the glass for radio or DAB reception; replacement must carry the matching antenna print and connector so reception is restored.
On your Mercedes GL
Confirmed during the quote process — integrated antennas are standard on most GL-Class variants from 2009 onwards.
GPS2
2005–2013On the Mercedes GL: fitted on every one of the 2 rear window variants we list; model years 2005–2013.
What it means
A GPS antenna laminated into the rear window, connecting your vehicle's satellite-navigation receiver to an aerial so the nav system receives position data.
On your Mercedes GL
Confirmed during the quote process; typical on GL-Class models with integrated sat-nav from the late 2000s onwards.
Grey Privacy2
2005–2013On the Mercedes GL: fitted on every one of the 2 rear window variants we list; model years 2005–2013.
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.
Heated Rear Windscreen2
2005–2013On the Mercedes GL: fitted on every one of the 2 rear window variants we list; model years 2005–2013.
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.
About the Mercedes GL
The Mercedes GL-Class ran from 2005 to 2013 as a full-size luxury SUV, spanning two main generations. Early models (2005–2009) carried straightforward toughened rear glass with essential heating elements, whilst later variants introduced integrated antenna technology and, on some trims, privacy tinting for enhanced cabin security.
From around 2009 onwards, GPS antenna integration and anti-theft alarm wiring became available on certain specifications, reflecting Mercedes' push towards connected in-vehicle systems. Most GL-Class rear windows are toughened glass — a tougher, quicker-breaking compound than laminated — because the rear doesn't bear the same structural load as the windscreen.
