GENUINE LAND ROVER DISCOVERY 4 L319 FRONT LEFT N/S SEAT HEATING ELEMENT – AH22-603B20


Genuine used Land Rover front seat heating element removed from a 2010 Land Rover Discovery 4 L319.


This heating element forms part of the heated front-seat system and is fitted within the front left / passenger-side seat on UK RHD vehicles.


Part / Engineering Number: AH22-603B20

Part Type: Front Seat Heating Element / Heater Pad

Position: Front Left Seat

Vehicle Side: N/S – Nearside / Passenger Side on UK RHD vehicles

System: Heated Front Seat System

Manufacturer: Genuine Land Rover / OEM

Donor Vehicle: 2010 Land Rover Discovery 4 L319

Condition: Used genuine OEM part


COMPATIBILITY


Suitable for applications within the:


• Land Rover Discovery 4 / L319 – 2010-2016

• UK RHD front left / passenger seat applications

• Vehicles equipped with heated front seats

• May be applicable across 2.7 TDV6, 3.0 TDV6 and 3.0 SDV6 Discovery 4 models where the same seat specification and heating element are fitted


The Discovery 4 uses different seat components depending on seat specification, upholstery, electrical adjustment, memory equipment and other options. AH22-603B20 should therefore be matched against the number on the original heating element, connector configuration and seat specification before purchase.


TECHNICAL INFORMATION


The front seat heating system uses electrical heating elements incorporated into the seat assembly.


When the heated-seat function is selected, electrical current passes through the heating element to warm the seat. The vehicle’s seat heating system monitors and regulates operation to maintain the selected heat level.


The Discovery 4 heated-seat system works together with the:


• Seat heating element

• Seat temperature sensing system

• Heated-seat control module

• Climate control system

• Seat wiring harness and electrical connectors


FRONT SEAT HEATING SYSTEM INFORMATION


Discovery 4 front heated seats are electronically controlled rather than simply receiving a permanent 12V supply.


A heating fault can therefore be caused by the heating element itself, wiring/connectors, temperature sensing circuit, heated-seat control module or associated vehicle electronics.


COMMON SYMPTOMS / REASONS FOR REPLACEMENT


• Front passenger seat no longer heats

• Seat heats intermittently

• Heating cuts out shortly after being switched on

• Open circuit within the heating element

• Damaged or broken heating-element wiring

• Uneven heating across the seat

• Heated-seat diagnostic fault stored

• Damage discovered during seat upholstery repair


IMPORTANT DIAGNOSTIC INFORMATION


Before replacing the element, check the seat wiring, connectors and heater control system.


Land Rover diagnostic information includes faults relating specifically to left front seat heater element electrical failure, which can be caused by an open/short circuit, failed heating element, heated-seat module or associated control system.


INSTALLATION


Installation normally requires removal or partial dismantling of the front seat and removal of the seat upholstery to access the heating element.


Take particular care around:


• Seat side-airbag wiring

• Occupancy/safety-system wiring where fitted

• Seat adjustment wiring

• Heating-element connectors

• Upholstery retaining clips and fasteners


Disconnect the vehicle battery and follow the correct Land Rover workshop procedure before disconnecting seat/SRS electrical connections.


PROGRAMMING / CODING


The heating element itself would not normally require programming or coding when replacing it with the correct equivalent component.


Any stored heated-seat fault codes may need to be diagnosed and cleared after installation.


IMPORTANT COMPATIBILITY NOTE


AH22-603B20 appears to be an engineering/manufacturing reference rather than a confirmed Land Rover retail LR-number.


Please compare:


• AH22-603B20 marking

• Electrical connector

• Wiring configuration

• Heating-pad shape

• Seat specification

• Vehicle VIN / original component


before ordering.


Do not rely on model and year alone, as Discovery 4 front seats were available in several specifications.


CONDITION


Genuine used Land Rover part.


Please expect normal signs of previous use consistent with a used internal seat component.


Ideal replacement for a damaged or failed original front left heated-seat element where the AH22-603B20 specification matches.
