Genuine used Land Rover electric seat adjustment motor removed from a 2010 Land Rover Discovery 4 L319. This motor forms part of the electrically adjustable front seat mechanism and is suitable for replacing a failed or damaged original motor.
Part Number / Motor Marking: 404963
Part Type: Electric Seat Adjustment / Control Motor
Position: Front Left Seat
UK Vehicle Side: N/S – Nearside / Passenger Side on UK RHD vehicles
Application: Electric front seat adjustment system
Donor Vehicle: Land Rover Discovery 4 L319
Donor Year: 2010
Manufacturer: Genuine OEM specification
Condition: Used
Compatibility:
Land Rover Discovery 4 / LR4 (L319)
2009–2016
Confirmed examples of 404963 are listed on Discovery IV L319 vehicles, including 3.0 diesel applications.
The 404963 motor marking is also found on related Land Rover seat assemblies, including certain:
Land Rover Discovery 3 (L319)
2004–2009 – depending on seat specification
Range Rover Sport (L320)
Selected models – depending on electric seat specification
Because Land Rover used several different motors within one powered seat assembly, compatibility must be checked by the 404963 marking, electrical connector, mounting points, drive connection and exact position within the seat mechanism.
Technical Information:
This electric motor forms part of the powered seat adjustment mechanism.
When the corresponding seat adjustment switch is operated, the motor drives the appropriate mechanical seat adjuster through the factory transmission/drive mechanism.
A powered front seat can contain several separate adjustment motors controlling different functions, so 404963 should not be assumed to replace every motor fitted to the seat.
Electric Seat System Information:
Works in conjunction with the vehicle’s:
* Seat adjustment switches
* Seat wiring harness
* Seat control electronics where fitted
* Mechanical adjustment mechanism
* Seat rails / adjustment drives
* Other individual seat motors
Common Symptoms / Reasons for Replacement:
* One seat adjustment function stops working
* Motor does not operate when the switch is pressed
* Intermittent seat movement
* Motor operates slowly or becomes noisy
* Internal motor failure
* Damaged electrical connector
* Seat mechanism works in other directions but one adjustment function does not
* Replacement required after seat frame or mechanism repair
Important Diagnostic Information:
Before replacing the motor, check the relevant seat fuse, wiring, electrical connector, adjustment switch and mechanical drive.
A seat that does not move is not automatically caused by a failed motor. A damaged drive mechanism, wiring fault or seat control issue can produce similar symptoms.
Installation:
Designed to fit into the original powered seat adjustment mechanism.
The replacement motor should be compared directly with the removed unit, particularly the:
* 404963 identification
* Connector type
* Mounting arrangement
* Motor body
* Drive/output connection
* Position within the seat
Disconnect the vehicle battery and follow the correct manufacturer procedure before disconnecting electrical seat components, particularly where seat-mounted airbag and occupancy-system wiring is present.
Programming / Coding:
The motor itself would not normally require programming when replacing an identical unit. Any seat-memory or control-module procedures depend on the vehicle’s equipment specification.
Important Compatibility Note:
Please match 404963 with your original motor before ordering.
Discovery 4 powered seats use multiple adjustment motors, and visually similar motors can have different drive arrangements or functions. Vehicle model and year alone are not sufficient to guarantee compatibility.
Condition:
Genuine used part. Normal age-related cosmetic marks may be present from previous use and removal. Please inspect the listing photographs and compare all numbers, connectors and mounting points with your original part.
