Replacement of the windshield washer fluid pump on a 2024 Tesla Model 3 Long Range. The pump is mounted in the washer fluid reservoir, accessed from the front trunk area after removing the front wheel liner or fender access points.

Warnings

Tools required

Parts

• Windshield washer pump × 1 — Tesla Model 3 OEM washer fluid pump — match by VIN at parts counter
• Washer pump grommet (rubber seal) × 1 — OEM replacement grommet — often supplied with pump

Fluids

• Windshield Washer Fluid — 3.5 qt

Preparation

1. Park on level ground, place in P, engage parking brake.
2. Exit ALL doors with the 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 the 2024 Model 3, the 12V battery is typically located behind the right rear seat back panel (some 2024+ builds use a lithium 12V under the floor — verify 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. Drain the washer reservoir by activating the washers (with 12V still connected, before disconnecting) until the pump runs dry, OR plan to catch residual fluid (~3 qt possible) when the pump is pulled.
7. Open the frunk and remove any cargo. Identify the washer fluid reservoir fill neck location for orientation.
8. Turn the front wheels to gain access to the front wheel liner on the side where the reservoir/pump is mounted (typically passenger side on Model 3).

Procedure

1. 1

   Access the washer pump
   From under the front of the vehicle or through the front wheel liner access point, locate the washer fluid reservoir and the pump mounted at its lower side. On the Model 3, access is typically gained by removing the front fascia lower trim or partially detaching the wheel liner using plastic trim tools and T20 fasteners. Set fasteners aside in order.
2. 2

   Position drain pan
   Place a drain pan directly beneath the pump location. Even after running the reservoir empty, residual fluid will leak out when the pump is removed.
3. 3

   Disconnect electrical connector
   Locate the electrical connector at the washer pump. Depress the locking tab and pull the connector straight off. Inspect the connector pins for corrosion or fluid intrusion — clean with electrical contact cleaner if needed.
   ⚠Connectors become brittle in cold weather. Do not yank by the wires.
4. 4

   Disconnect washer hose
   Carefully pull the washer fluid supply hose off the pump outlet barb. Have a rag ready to catch fluid. If the hose is stuck, gently twist while pulling — do not cut the hose.
5. 5

   Remove the pump from the reservoir
   Grasp the pump body and pull it straight out of the rubber grommet seal in the side of the reservoir. Twisting slightly while pulling helps release the grommet's grip. Allow remaining fluid to drain into the pan.
   ⚠Do not pry against the reservoir with metal tools — the plastic can crack.
6. 6

   Inspect and replace the grommet
   Inspect the rubber grommet in the reservoir wall. If hardened, torn, or deformed, replace it. A failed grommet will leak even with a new pump installed. Lightly lubricate the new grommet with a drop of clean washer fluid (not petroleum-based lubricant, which degrades the rubber).
7. 7

   Install the new pump
   Press the new pump straight into the grommet until fully seated. It should require firm pressure but not excessive force. Verify the pump body is flush against the reservoir.
8. 8

   Reconnect hose and electrical connector
   Push the washer hose fully onto the pump outlet barb. Reconnect the electrical connector until the locking tab clicks. Verify both are fully seated — partial seating causes leaks and intermittent operation.
9. 9

   Refill the reservoir
   Refill the washer reservoir with fresh windshield washer fluid (approximately 3.5 qt capacity). Do not overfill above the fill neck.
   ℹ️In cold climates, use winter-rated washer fluid to prevent the reservoir and pump from freezing.

Reassembly

1. Reinstall the wheel liner or fascia trim panels removed for access. Seat all push pins and torque any screws to OEM specification — refer to Tesla Service Manual.
2. Reconnect the 12V low-voltage battery. Torque battery terminal bolts.
3. Close the frunk and verify the latch engages properly.
4. Allow the vehicle to fully wake up (approximately 30-60 seconds) before testing systems.

Verification

• With the vehicle awake, activate the front washer from the steering wheel stalk. Verify fluid sprays evenly from both nozzles within 1-2 seconds of activation.
• Activate the rear/camera washer if equipped and verify operation.
• Inspect the pump-to-reservoir grommet area and the hose connection for any drips or seepage after 3-4 spray cycles.
• Check the touchscreen for any 'low washer fluid' warnings — clear if necessary by topping off.
• After a short drive, recheck for leaks under the vehicle near the reservoir.
