If you own a manual transmission Land Rover Defender (pre-2007), you know that keeping the rear cabin area comfortable, especially in longer wheelbase 110 and 130 models, is a challenge. Poor air circulation means rear passengers are often left in the heat while the front stays cool.

Our secondary HVAC system is the perfect solution, delivering powerful heating and cooling directly to rear seat passengers. Unlike simple ducting that transfers air from the front, this system features its own evaporator and heater cores, making it a true rear air conditioning and heating unit.

Sitting neatly between the front seats, this compact but highly efficient system is powered by a three-speed blower, ensuring even air distribution for a balanced, comfortable cabin environment. Whether it's the height of summer or the depths of winter, every passenger gets optimal climate control.

Seamless Integration & Installation

Our rear HVAC system plumbs directly into the existing AC and heating lines, ensuring smooth operation without compromising the Defender's rugged reliability.

✔   Rear AC Plumbing - Connects via T-sections into your existing front AC system for a seamless refrigerant flow.

✔   Rear Heater Integration - Uses a T-piece connection to tap into the Defender's heating system.

Effortless Wiring & Control

Installing our rear HVAC system is straightforward, whether you're adding it to an existing front AC unit or installing a full front-and-rear system.

✔   Adding to an Existing Front AC: Simple wiring setup includes solenoid trigger and dashboard backlight feed.

✔   Complete Front & Rear HVAC Install: Comes with a plug-and-play wiring harness and control module.

For full installations, our relay box/control module sits in the battery box, connecting directly to the terminals, with all plugs clearly labeled for an easy fit. Laying out the wiring loom before installation helps visualize the setup for a smooth, efficient install.
