Lexus RX 400 rear window replacement — booked online.

What to expect during your Lexus RX 400 rear window replacement

Booking a rear-window replacement is straightforward — from instant quote to fitted glass in your driveway.

1. 1

   Start with a quick online quote through our guided variant quiz — takes about a minute to confirm your exact RX 400 specification.

2. 2

   Once booked, our parts check team verifies your replacement glass matches the antenna and heating-element configuration of your original.

3. 3

   You'll be matched with a specialist in your area who will arrange a convenient fitting slot — typically within 2–5 working days.

4. 4

   On the day, your fitter will remove the shattered original glass and fit the replacement. A shattered rear window means shard cleanup is a major part of the job; your fitter will remove accessible shards, though small fragments can lodge in places requiring deeper access.

5. 5

   We recommend a professional interior valet afterwards to ensure thorough detailing, especially if you want every trace of glass cleaned from under seats and trim areas.

6. 6

   Your replacement comes with a two-year warranty covering workmanship and glass quality.

Once fitted and confirmed road-ready by your technician, you're back on the road — book online today.

• Antenna2

  2003–2009

  An aerial laminated into the windscreen or rear window restores radio, DAB or TV reception without a roof-mounted mast.

  What it means

  An antenna is a conductive print laminated into the glass during manufacture, typically used for radio, DAB (digital audio broadcasting) or television reception. It replaces the traditional roof-mounted aerial mast found on older vehicles. The antenna is integrated into the glass interlayer and connected to the vehicle's receiver unit via a connector embedded in the glass edge. This design offers a cleaner aesthetic, reduces wind noise, and eliminates the vulnerability of a protruding mast to damage or theft.

  How to tell

  Check your vehicle's roof — if there is no visible aerial mast, your car likely has a laminated antenna. You can also ask your dealer or service centre whether your windscreen or rear window carries an antenna print. The connector may be visible on the glass edge or inside the door frame trim.

  Replacement impact

  When replacing glass with a laminated antenna, the replacement must carry the matching antenna print and connector to restore reception immediately on fitting. Aftermarket or original-equipment glass with the correct antenna specification is essential; a plain replacement will leave you without radio or DAB signal. Our fitters verify the antenna specification during booking and source the correct variant before the appointment.

• Bronze Privacy2

  2003–2009

  Dark Bronze is a factory tint applied to rear windows and doors for privacy and heat reduction.

  What it means

  Dark Bronze, officially known as Privacy Glass, is a tinted glass feature created during manufacturing through a deep-dipping process. The inside surface of the glass is dyed with dark pigment, giving the rear half of the vehicle a darker appearance than the front. This serves two purposes: it reduces glare and heat entering the rear cabin, and it provides occupants with greater privacy by limiting visibility into the rear passenger area from outside. It's a permanent feature of the glass itself, not a removable film or coating.

  How to tell

  Look at your rear door windows and rear window — if they're noticeably darker than your front windscreen and front door windows, you have Dark Bronze tint. You can also check your vehicle's specification sheet or contact your dealer to confirm whether Privacy Glass was fitted as standard on your model.

  Replacement impact

  Dark Bronze replacement glass must match the original tint level to maintain the vehicle's appearance and privacy. OE (original equipment) glass with the correct tint is essential — aftermarket untinted glass will look visibly lighter and won't provide the same heat or privacy performance. When we source your replacement, we confirm the exact tint specification for your vehicle to ensure a perfect match.

• Heated Rear Windscreen2

  2003–2009

  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.
