Blower Control Upgrade Kit

Older Defender heater fans are known for poor performance and reliability, particularly in colder, wetter climates. This retrofit electronic control system replaces the outdated analogue setup, offering smooth, continuous adjustment for improved airflow, heating, and dehumidification. The result is faster cabin warming, more effective demisting and de-icing, and greater durability thanks to reduced wear from vibrations and shocks. Kit includes electronic control unit, stepless slider, all required fittings, and installation instructions. Defender - 1987 - 2006
