Replace the windshield washer fluid pump on a 2024 Tesla Model 3 Performance. The pump is mounted to the side of the washer fluid reservoir in the front trunk (frunk) area and is accessed from the front wheel well or frunk liner.

Warnings

Tools required

Parts

• Washer fluid pump (Model 3 specification) × 1 — OEM Tesla Model 3 windshield washer pump
• Pump grommet / seal (recommended replacement) × 1 — OEM washer pump rubber grommet

Fluids

• Windshield Washer Fluid (refill after service) — 3.5 qt

Preparation

1. Park on level ground, place in P, engage parking brake.
2. Exit ALL doors with key fob away from the vehicle. Wait at least 2 minutes for HV systems to fully de-energize, even on this non-HV job.
3. Disconnect the 12V low-voltage battery. On 2024 Model 3, the 12V (lithium) battery is located behind the right rear seat back panel or under the frunk floor depending on production date — verify location before disconnecting.
4. DO NOT touch, cut, or pierce ANY orange cable — these are high-voltage and lethal.
5. If at any point you encounter an orange cable, an HV component, or are unsure if a system is de-energized: STOP and consult a Tesla-certified technician.
6. Optional: Use the touchscreen washer fluid level indicator to confirm fluid quantity. If full, spray washers continuously to lower the level before removal to reduce spillage.
7. Turn the front wheels to the right to gain access to the left front wheel well (the washer reservoir on Model 3 is located behind the left front wheel liner).

Procedure

1. 1

   Raise and support the front of the vehicle (optional)
   If additional access is needed, lift the front of the Model 3 using the manufacturer-specified jack pads at the designated lift points. Support on jack stands. The pump can often be reached without lifting if the wheel is turned fully to the right.
   ⚠Use only Tesla-specified lift points with a puck adapter. Lifting on the battery pack or pinch welds will damage the vehicle.
2. 2

   Remove the left front wheel well liner fasteners
   Locate the front section of the left front wheel well liner. Using a plastic trim tool, remove the push-pin retainers and any T20/T25 Torx screws securing the forward portion of the liner. You only need to peel the liner back enough to expose the washer reservoir and pump — full removal is usually unnecessary.
3. 3

   Peel back the wheel liner and locate the pump
   Carefully fold the wheel well liner back to expose the side of the washer fluid reservoir. The washer pump is mounted low on the reservoir, with an electrical connector on top and a fluid hose on the outlet. There may be one or two pumps (front and rear, or front only) depending on configuration — identify the correct pump for your symptom.
4. 4

   Disconnect the electrical connector
   Press the release tab on the pump's electrical connector and pull it straight off. Inspect the terminals for corrosion or damage. Do not pull on the wire harness.
5. 5

   Position drain pan and disconnect washer hose
   Place a drain pan directly beneath the pump. Squeeze the hose clamp or release the quick-connect fitting on the washer hose and pull the hose off the pump outlet. Fluid will begin to drain — be ready to cap the hose or let the reservoir empty into the pan.
   ⚠Washer fluid contains methanol/ethanol — keep away from skin, eyes, and painted surfaces. Wipe up spills immediately.
6. 6

   Remove the pump from the reservoir
   Grasp the pump body and twist gently while pulling straight outward to release it from the rubber grommet in the reservoir wall. Allow remaining fluid to drain. Inspect the grommet — if it is hardened, cracked, or distorted, replace it to prevent leaks.
   ℹ️Do not use pliers on the pump body — plastic housings crack easily.
7. 7

   Inspect reservoir port and grommet
   Wipe the reservoir port clean. Inspect for debris inside the reservoir that could clog the new pump's intake screen. Install the new grommet if replacing.

Reassembly

1. Lubricate the new grommet (and the pump's inlet stub) lightly with clean washer fluid — do not use petroleum grease, which will degrade the rubber.
2. Press the new pump straight into the grommet until fully seated. It should sit flush against the reservoir wall with no visible gap.
3. Reconnect the washer hose to the pump outlet. Ensure the hose clamp or quick-connect is fully engaged.
4. Reconnect the electrical connector until it clicks.
5. Reposition the wheel well liner and reinstall all push-pin retainers and Torx screws. Torque any threaded fasteners to OEM specification — refer to Tesla Service Manual.
6. Lower the vehicle if it was raised.
7. Refill the washer reservoir with up to 3.5 quarts of windshield washer fluid suitable for your climate (use winter-formula in freezing temperatures).
8. Reconnect the 12V low-voltage battery. Torque the battery terminal hardware per the Battery Terminal Bolts specification.
9. Close the frunk and allow the vehicle to wake up — verify the touchscreen powers on normally.

Verification

• From the touchscreen, activate the windshield washers (Controls → Service, or pull the stalk/press the wiper button as configured for your build) and confirm strong, even spray from both windshield nozzles.
• If equipped with a rear washer (not standard on Model 3 — verify), test that as well.
• Inspect the pump-to-reservoir grommet area and the hose connection for leaks after operating the washers 3–4 times.
• Check the touchscreen for any new alerts or fault codes related to the washer system.
• Confirm washer fluid level reads correctly on the touchscreen — Model 3 displays a 'Low Washer Fluid' alert when low; this should clear after refill.
• Reinspect the wheel well liner is fully seated with no gaps that could allow road spray into the frunk area.
