Technical Information
The switch provides electrical control of the corresponding door’s window regulator/motor.
The Discovery 4 electric-window system provides one-touch operation on all four windows. A brief full press or pull allows the window to continue opening or closing automatically until stopped or until it reaches the end of its travel. (manualzz.com)
Electric Window System Information
This switch works as part of a system that includes:
• Door window control switch
• Door wiring loom
• Electrical connectors
• Window regulator
• Window motor
• Vehicle electrical/control system
A window that fails to operate is not necessarily caused by the switch.
The regulator, motor, wiring and electrical connections should also be checked before replacement.
Common Symptoms / Reasons for Replacement
• Window does not operate from rear door switch
• Intermittent window operation
• Switch only works in one direction
• Button sticking or physically damaged
• Switch illumination fault
• Electrical contacts worn
• Connector or switch housing damaged
• Original switch missing
• Replacement required following door-card repair
Important Diagnostic Information
Before replacing the switch, check:
• Window operation from the driver’s master controls
• Rear window isolator/child-control function
• Window motor and regulator
• Door wiring loom
• Electrical connector
• Fuse/electrical supply where applicable
If the window works correctly from the driver’s master switch but not from the rear-door switch, the rear switch or its local wiring/connection should be investigated.
Installation
Designed to fit into the original rear-door switch mounting position.
Depending on the trim arrangement, access to the rear of the switch/door trim may be required.
Care should be taken when releasing the plastic retaining clips and electrical connector.
Programming / Coding
No conventional ECU programming or coding is normally required for a like-for-like window switch replacement.
After electrical work or loss of battery supply, the electric-window one-touch function may require reinitialisation/reset if it no longer operates correctly.
Important Compatibility Note
⚠️ Please compare your original switch before ordering.
Check:
• Part / engineering number
• AH22-14717-AB where applicable
• Connector shape
• Number of electrical pins
• Switch button design
• Mounting arrangement
• Rear right / O/S application
• Listing photographs
Land Rover used different revisions and superseded part numbers during production.
Do not purchase solely by vehicle model and year. The original switch number and connector are the safest compatibility checks.
Condition
Genuine used Land Rover part.
May show normal signs of previous use, including light scratches, marks and cosmetic wear around the button or housing.
Please inspect all listing photographs carefully as they form part of the item description.
