Land Rover Part Number: HHL500150 - Seat Adjuster Motor
HHL500150 is a Seat Adjuster Motor fitted within the front seat base to drive electric adjustment on driver memory and non-memory front seats. The motor converts electrical input from the seat switch and memory control module into mechanical movement, engaging the seat adjuster gearbox to move the driver-side seat. It interfaces with the seat wiring harness and mounts to the seat frame; replacement is typically required when the motor does not respond to switch inputs, produces abnormal noise under load, or fails to drive the adjuster gearbox.
