Technical Information
This is a compact electric actuator motor fitted within the powered front seat frame.
Depending on the seat mechanism and installation position, electric seat motors can operate functions such as:
• Seat base movement
• Seat height adjustment
• Seat tilt adjustment
• Fore/aft movement
• Backrest/recline mechanism
The exact function performed by this motor can depend on its mounting position within the seat frame.
Electric Seat System Information
The Discovery 4 electric front seat uses multiple motors and mechanical drive components to provide the various seat adjustment functions.
The seat adjustment switch sends the driver’s or passenger’s input through the appropriate electrical system, allowing the relevant motor to operate the seat mechanism.
Because several motors can be fitted to one seat, they can look very similar while having different drive arrangements or part numbers.
Common Symptoms / Reasons for Replacement
• One seat adjustment function has stopped working
• Motor does not operate when the seat switch is pressed
• Intermittent seat movement
• Motor operates slowly or inconsistently
• Internal motor failure
• Damaged motor connector
• Motor damaged during seat mechanism repair
• Replacement of damaged electric seat frame components
Important Diagnostic Information
If one electric seat function is not operating, the motor should not automatically be assumed faulty.
Before replacement, check:
• Seat adjustment switch
• Seat wiring harness
• Electrical connectors
• Power and ground supply
• Seat control electronics where fitted
• Mechanical drive cables/gears
• Seat rails and adjustment mechanism
If the motor can be heard running but the seat does not move, the problem may be within the mechanical drive system rather than the motor itself.
Installation
The motor is fitted to the electric seat frame and should be installed in the same position as the original unit.
Access may require partial removal or dismantling of the front seat.
Disconnect the vehicle battery according to the manufacturer’s procedure before disconnecting electrical equipment underneath the seat, particularly because SRS/airbag wiring is also located in this area.
Programming / Coding
The electric adjustment motor itself normally does not require programming or coding.
Once the correct motor is installed and connected, it operates through the existing seat electrical system.
Important Compatibility Note
Please match 404904 / 82148141-4 / 821481414 against your original motor before purchasing.
Discovery 4 front seats can contain several different adjustment motors. Do not purchase solely because your vehicle is a Discovery 4 or because the motor was removed from the same side.
Please compare:
• Motor number
• Electrical connector
• Plug pin arrangement
• Motor body
• Drive connection
• Mounting points
• Original motor position
with your existing part and the listing photographs.
Condition
Used genuine OE electric seat adjustment motor.
Normal cosmetic signs of previous use and removal may be present. Please inspect the listing photographs carefully for the exact condition and item supplied.
