2019-2024 Jaguar I-PACE Headlight Washer Pump: Diagnosis and Replacement

Symptoms of a Failing Headlight Washer Pump

Failure of the headlight washer pump on the 2019-2024 Jaguar I-PACE typically presents in a few straightforward ways. Because the I-PACE uses a dedicated pump for the headlights separate from the windshield washers, you may experience a failure of one system while the other continues to work perfectly.

• No Spray from Headlight Jets: This is the most common symptom. When you activate the headlight washers (which typically requires the headlights to be on), nothing happens. The pop-up nozzles may not even appear, or they may rise from the bumper but produce no spray.
• No Pump Noise: When the system is activated, you should hear a distinct whirring or humming sound from the pump motor, usually located near the front of the vehicle by the washer fluid reservoir. If you hear complete silence, it points to either a dead pump motor, a blown fuse, or a bad electrical connection.
• Weak or Uneven Spray: If the fluid only dribbles out or fails to cover the headlight lens, the pump motor may be wearing out and losing its ability to generate sufficient pressure. This can also be caused by a clogged line or nozzle, but a weak pump is a common culprit.
• Pump Runs Continuously or Makes Grinding Noises: A grinding or squealing sound indicates the pump motor is running, but it may not be moving fluid due to an internal failure or an air lock in the system. If the pump fails to shut off, it could be due to a stuck relay or internal fault.
• Washer Fluid Leaks: Puddles of washer fluid under the front of the vehicle can indicate a cracked pump housing or a failed seal. These pumps are made of plastic and can become brittle over time, leading to leaks at the housing or where the hoses connect.

Known Issues, TSBs, and Recalls

As of mid-2024, there are no specific recalls, Technical Service Bulletins (TSBs), or widespread documented issues for the headlight washer pump on the 2019-2024 Jaguar I-PACE. The vehicle has several recalls related to its high-voltage battery system and other electronics, but the washer system has proven to be reliable.

However, owners may experience issues common to all vehicles with this feature:

• Freezing: In cold climates, if the washer fluid is not rated for low temperatures, the lines or the pump itself can freeze. This can cause the pop-up nozzles to get stuck in the 'out' position or prevent the system from spraying.
• Connector Corrosion: The pump is located low in the vehicle and is exposed to moisture and road salt. Over time, this can cause corrosion on the electrical connector, leading to intermittent or total failure.

Step-by-Step Diagnosis

1. Check Fluid Level: The most common reason for a washer system not working is an empty reservoir. Ensure the reservoir is filled with a quality washer fluid.
2. Check the Fuse: Consult your owner's manual for the fuse box diagram and locate the fuse for the "Power Wash Pump" or headlight washers. On some Jaguar models, this is located in the engine bay fuse box. A blown fuse is a simple fix and should always be the first electrical check.
3. Listen for the Pump: Have a helper activate the headlight washers while you stand near the front of the car. Remember, the headlights must be on for the system to activate. If you hear a hum, the pump is receiving power. If you hear nothing, the problem is likely electrical (fuse, relay, wiring, or the pump motor itself).
4. Inspect for Leaks: If you hear the pump but see no spray, check for fluid leaking onto the ground. This points to a broken line or a cracked pump housing.
5. Test for Power: If the fuse is good but the pump is silent, the next step is to access the pump's electrical connector. This usually requires removing the front bumper or fender liner. Using a multimeter, check for voltage at the connector when the system is activated. If you have power and ground, but the pump doesn't run, the pump has failed and needs replacement.

Buying a Used Headlight Washer Pump

Given the lack of aftermarket options for the I-PACE, a used OEM pump is an excellent, cost-effective alternative to a new part from a Jaguar dealer. Here’s what to look for when buying a recycled part:

• Verify the Part Number: Ensure you are buying part number T4K6019. While pumps from other Jaguar models may look similar, they may not have the correct pressure rating or mounting points. Using the wrong pump can result in weak spray performance.
• Inspect the Electrical Connector: Ask for clear photos of the electrical pins inside the connector. Look for any signs of green or white corrosion, which indicates moisture intrusion and potential electrical issues. Avoid any pump with a corroded connector.
• Check for Cracks: Carefully inspect the plastic housing, especially around the inlet/outlet ports and the base where the motor sits. Any visible cracks will cause leaks.
• Source Vehicle Information: If possible, buy from a seller who can provide the mileage of the donor vehicle. A pump from a low-mileage I-PACE is always preferable. A used pump from a 2022 I-PACE with 29k miles has been seen on the market, which is a good indicator of available quality.
• Warranty and Return Policy: Only buy from sellers who offer a warranty and a clear return policy. This protects you in case the part is dead on arrival.

Cost & Replacement Info

Replacing the headlight washer pump is a moderately difficult job, primarily because of the need to access its location behind the front bumper cover or wheel arch liner.

The installation typically involves removing the front passenger-side wheel, detaching the fender liner, draining the washer reservoir, unclipping the electrical connector and hoses, and swapping the pump. The pump itself is usually held in place by a simple grommet or clip.
