🔥The Proper Rear Window Upgrade for Commercial Defenders🔥

After a rear seat conversion, working rear windows are not a luxury — they are an essential safety upgrade.

Commercial Defenders are not built with operational rear windows, meaning the rear window motors, switches and vehicle systems are not fully wired or activated. We provide a complete, professional upgrade using official parts, correct wiring, full vehicle coding and proper activation through the BCM.

This gives you fully functioning rear windows from both the front and rear switches, with child lock and window lock functionality working as it should.

Unlike basic aftermarket fixes or partial wiring jobs, our upgrade is carried out properly from start to finish. No shortcuts. No unsafe workarounds. No half-functionality.

For families adding rear seats to a commercial Defender, this is the safe, factory-style solution — and the upgrade your children deserve in the back.
