1994-2004 Discovery Mirror Switch: Understanding D1 vs. D2 Compatibility
This guide clarifies the critical differences between the power mirror switches used in Discovery 1 and Discovery 2 models, helping you get the right part the first time.
- The most critical step is identifying your vehicle correctly: Discovery 1 (1994-99) and Discovery 2 (1999-04) use different, non-interchangeable mirror switches.
- Failure is almost always due to internal wear or corrosion in the switch itself, making it a non-repairable part.
- Symptoms include total lack of movement, intermittent function, or failure to adjust in specific directions.
- Replacement is extremely easy, requiring only a trim tool to pop the switch out of the center console, making it a perfect DIY job.
Key Compatibility Warning: Discovery 1 vs. Discovery 2
Important: The 1994-2004 Land Rover Discovery spans two distinct generations, and they use different power mirror switches. Do not assume the parts are interchangeable based on the year alone, especially for 1999 models which could be either generation.
- Discovery 1 (1994-1999): Uses a rectangular switch with a sliding selector, part number AMR2498.
- Discovery 2 (1999-2004): Uses a rotary knob switch. While some parts suppliers list AMR2498 for the Discovery 2, owner forums and specialists confirm the correct switch is a different design. Always verify by visually comparing your old switch to the replacement part.
This guide covers both generations, but you must identify which Discovery you own before purchasing a part.
Symptoms of a Failing Power Mirror Switch
A failing mirror switch is usually an electrical issue within the switch unit itself. The internal contacts can wear out or corrode, or the circuit board can fail. Symptoms are typically straightforward:
- Mirrors won't adjust at all: When you move the switch, nothing happens. Before blaming the switch, check the fuse and ensure the selector is not in a neutral position.
- Partial failure (one direction doesn't work): The mirror may adjust up and down but not left and right, or vice-versa. This points to specific worn-out contacts inside the switch for that direction.
- Intermittent operation: The switch works sometimes but not others. This can be caused by loose internal connections or corrosion.
- Only one mirror adjusts: If you can select and adjust one mirror but not the other, the fault is likely within the switch's selector mechanism.
- Related electrical issues (Discovery 2): On some Discovery 2 models, issues with the ignition switch can cause intermittent power loss to the mirror switch and HVAC controls simultaneously. If both systems are failing together, the ignition switch wiring may be the culprit.
Buying a Used Mirror Switch: What to Look For
Since these switches are generally not repairable, a used OEM unit is a cost-effective solution. Here’s what to check:
- Verify the Part Number and Style: This is the most critical step. For a Discovery 1, you need AMR2498. For a Discovery 2, you need the rotary style switch. Have a photo of your original part ready for comparison.
- Inspect the Joystick/Knob: The control knob or joystick should move smoothly without being excessively loose or stiff. Any physical damage or sloppiness could indicate internal wear.
- Check the Connector Pins: Look at the electrical connector on the back. The pins should be straight, clean, and free of any green or white corrosion.
- Ask About Testing: Ask the seller if the part was tested before being removed from the vehicle. A reputable recycler will often test basic electronic functions.
- Why Used OEM is a Good Choice: For a simple electronic component like this, a used OEM switch that has been verified to work is often more reliable than a new, cheaply made aftermarket part. The original Land Rover parts have proven durability, and a used one avoids the high cost of a new dealer part.

How to Replace the Power Mirror Switch (DIY Guide)
Difficulty: 1 out of 5 (Very Easy)
Estimated Time: 15 minutes
The mirror switch is located in the center console, near the gear shifter and window switch pack. The replacement process is similar for both Discovery 1 and Discovery 2.
- Pry Up the Switch Panel: Using a plastic trim removal tool or a flathead screwdriver wrapped in tape (to prevent scratching), carefully pry up the edges of the console trim panel that holds the switches.
- Disconnect the Switch: Once the panel is lifted, you can access the underside of the mirror switch. Depress the locking tab on the electrical connector and pull it straight off the switch.
- Remove the Old Switch: The switch is held into the trim panel by plastic clips. Squeeze the clips from the underside and push the switch up and out of the panel.
- Install the New Switch: Press the new switch into the empty slot in the trim panel until it clicks securely in place.
- Reconnect and Test: Plug the electrical connector back into the new switch. Before snapping the trim panel back down, turn the ignition to the 'on' position and test all functions of the new switch (select left, select right, and all four directions for each mirror).
- Reinstall Panel: Once you've confirmed it works, press the trim panel firmly back into the center console.
Frequently Asked Questions (FAQ)
My mirrors move, but I hear a grinding noise. Is the switch bad?
No, if you hear a noise from the mirror housing when operating the switch, the switch is likely working correctly by sending power. The grinding noise indicates a problem with the mechanical linkage or the actuator motor inside the mirror assembly itself.
Is the mirror switch the same as the window switch?
No, they are separate components. On the Discovery, the mirror switch is a standalone unit located in the center console, often near the main window switch pack, but it is not integrated into it.
Can I use a Discovery 2 mirror assembly on a Discovery 1?
While the mirror assemblies look similar, the mounting base that attaches to the door has a different profile. It is not a direct bolt-on swap, though some owners have modified them to fit.
My mirrors and my HVAC controls stopped working at the same time. What's the problem?
On a Discovery 2, this is a known symptom of a failing ignition switch. A hairline crack or bad connection in the electrical part of the ignition switch can cause intermittent power loss to both of these systems. Before replacing the mirror switch, investigate the ignition switch wiring.
