Land Rover Part Number: LR023342 - Front Passenger Window Lift ECU
LR023342 is a Front Passenger Window Lift ECU. Fitted in the front passenger door, this module processes the door switch inputs and position sensor signals to drive the window motor via the door electronics. It also communicates with the vehicle's central electrical systems and safety interlocks so window behaviour matches door-locking and ignition states. Replacement is required when the module fails to respond to switch inputs, causes intermittent window movement, or reports communication faults; removal normally involves taking off the door trim and disconnecting the module wiring connector, and any required programming or diagnostic checks must be completed with the appropriate vehicle diagnostic tools.
