2019-2024 Jaguar I-Pace Wiper Arms: A Guide for Heated Windshields
This guide covers the unique heated washer jet wiper arms for the I-Pace, including failure symptoms, TSBs, replacement tips, and how to buy a good used set.
- These wiper arms are specific to 2019-2024 I-Pace models with the heated windshield/washer jet option (Part #s T4K4110 & T4K4111).
- The most common failures are a weak spring causing poor wiping and stripped splines at the pivot point causing the arm to stop moving.
- A special 'wiper arm puller' tool is strongly recommended for DIY replacement to avoid damaging the arm or vehicle.
- When buying used, the most important check is to inspect the splines inside the mounting hole for stripping.
Symptoms of a Failing Wiper Arm
A failing wiper arm can cause a range of issues from annoying noises to a serious loss of visibility. While the wiper motor provides the motion, the arm is responsible for applying the pressure. Here are the most common signs that your I-Pace's wiper arms need attention.
- Wiper Chattering or Skipping: This is the most frequent symptom and occurs when the arm's spring becomes weak. A weak spring can't hold the blade firmly against the glass, causing it to skip or vibrate as it moves, especially on a semi-dry windshield.
- Uneven or Incomplete Wiping: If you notice streaks or large patches of water left behind after the wiper passes, it often points to a bent arm or weak spring pressure. The arm isn't applying even force across the entire length of the blade.
- Wiper Lifts at Highway Speeds: If your wipers lift away from the windshield at speed, the spring is almost certainly worn out and can no longer counteract the force of the wind.
- Wiper Arm is Loose or Won't Move: If the wiper motor is running but one or both arms aren't moving, the splines inside the pivot point of the arm have likely stripped out. This is common if the wipers were turned on while frozen to the windshield. You may be able to wiggle the arm by hand at its base.
- Wipers Don't 'Park' Correctly: A Jaguar Technical Service Bulletin (TSB) notes an issue where wipers may stop in the 'up' position on the windshield instead of returning to the base. This can be related to the arm, linkage, or motor.
- Squeaking or Juddering: TSB #SFCC_SEP2023_45 was issued for 2020 I-Pace models where wiper blades "streak, smear, judder or squeak during operation." While the TSB may focus on the blades, these symptoms are often caused or made worse by incorrect arm tension.
Compatibility Warning: The primary wiper arms for the 2019-2024 I-Pace are specific to vehicles with the heated windshield/cold climate option. These arms incorporate heated washer jets. Part numbers are T4K4110 (Left/Driver side) and T4K4111 (Right/Passenger side). Using arms from a non-heated model will result in the loss of the heated washer function. Always verify your vehicle's options before purchasing.
Known Issues, Recalls, and Technical Service Bulletins (TSBs)
While there are numerous recalls for the I-Pace, they primarily concern the high-voltage battery system and do not involve the wiper arms. However, Jaguar has issued a few TSBs related to the wiper system that are helpful for diagnosis:
- TSB #SFCC_SEP2023_45: Addresses customer complaints of wiper blades that streak, smear, judder, or squeak during use on 2020 models. This points to a potential issue with the blade-to-glass interface, where arm tension plays a key role.
- Unnamed TSB for 2023 Models: A bulletin mentions that a customer may report the wipers stopping in the up position on the windshield when turned off. This indicates a potential problem in the parking mechanism of the wiper system.
Buying a Used 2019-2024 I-Pace Wiper Arm
Buying a used OEM wiper arm is an excellent way to save money, especially since specific aftermarket options for the heated-jet models are scarce. A recycled OEM part guarantees perfect fitment and the correct spring tension engineered for the I-Pace. Here’s what to inspect:
- Confirm the Part Number: This is the most critical step. You need T4K4110 for the left side and T4K4111 for the right side to retain the heated washer jet feature. Do not buy an arm without verifying these numbers.
- Inspect the Pivot Splines: Flip the arm over and look at the mounting hole. It should have clean, sharp metal teeth (splines). If the splines are rounded, flattened, or stripped, the arm will not lock onto the motor post and is useless. This is the most common failure point.
- Test the Spring Tension: Try to pull the arm open as if you were lifting it off the windshield. It should provide strong resistance. If it feels weak or flimsy compared to a new one or the other arm on your car, the spring is worn out and it will not wipe effectively.
- Check for Physical Damage: Look for cracks, especially around the pivot head and where the blade attaches. Check for any significant bends in the arm itself. Minor paint fading is acceptable, but structural damage is a red flag.
- Examine the Washer Jet and Hose: Ensure the plastic washer jet nozzle is not broken and that any attached hosing is not cracked or brittle.
Replacement Overview & Difficulty
Replacing the wiper arms on an I-Pace is a straightforward task for a DIYer with the right tool. Without it, the job can become very frustrating.

Key Steps & Tools
Pro Tip: A specialized windshield wiper arm puller tool is highly recommended. The arms are press-fit 🎬 See how a puller tool handles a seized wiper arm. onto the splined posts and can become seized over time. Trying to pry them off with a screwdriver can damage the arm, the cowl, or the wiper transmission.
🎬 Watch: How to safely remove a wiper arm without breaking glass.- Lift the small plastic cap at the base of the wiper arm to expose the retaining nut.
- Before loosening the nut, use a piece of masking tape on the windshield to mark the exact 'parked' position of the wiper blade. This ensures you install the new arm in the correct alignment.
- Remove the retaining nut (typically 13mm or 15mm).
- Use the wiper arm puller to safely and evenly press the arm off the splined post.
- Press the new arm onto the post, aligning the blade with your tape mark.
- Install and tighten the retaining nut. Do not overtighten, as this can strip the new arm.
- Test the wipers to ensure they operate correctly and park in the proper position before driving.

Frequently Asked Questions (FAQ)
How do I know if my I-Pace has heated washer jets?
The heated washer jets are part of the Cold Climate Pack, which also typically includes a heated windshield and heated steering wheel. You can check your vehicle's original window sticker or look for the heated windshield button on your climate control panel. The presence of very fine, zig-zagging wires within the windshield glass is also a clear indicator.
Do I have to replace both wiper arms at the same time?
No, you can replace only the failed arm. However, if one arm's spring has failed due to age, the other is likely not far behind. If you are replacing one due to a weak spring, it is often a good idea to replace both to ensure even pressure and wiping performance.
Can I use a regular wiper arm without the heated jet?
Physically, a non-heated arm might fit the splined post, but you would lose the heated washer functionality. You would also need to cap the washer fluid line that would normally connect to the arm, which is not recommended. For proper function, it is essential to use the correct OEM part.
My wiper arm nut is tight, but the arm still wobbles. What's wrong?
This is the classic symptom of stripped splines inside the wiper arm's mounting hole. The nut is tight against the post, but the soft aluminum splines inside the arm can no longer grip it. The arm must be replaced.
