Replacement of the windshield washer fluid pump on a 2024 Model Y Performance. The pump is mounted on the side of the washer fluid reservoir in the front trunk area and is accessed by removing fasteners and trim from the front fender liner / frunk lining.

Warnings

Tools required

Parts

• Windshield washer fluid pump (Model 3/Y compatible) × 1 — OEM-equivalent washer pump for 2024 Model Y
• Washer pump grommet/seal × 1 — Replace if torn or hardened — OEM spec

Fluids

• Windshield Washer Fluid — 3.5 qt

Preparation

1. Park on level ground, place vehicle in P, and engage the 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. Open the frunk and disconnect the 12V low-voltage battery (located in the front trunk area on 2024 Model Y). Loosen terminal per Battery Terminal Bolts spec.
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. Confirm you have a replacement pump and grommet on hand before draining the reservoir.
7. Place a drain pan under the washer reservoir/pump area to catch fluid loss when the pump is removed.

Procedure

1. 1

   Access the washer reservoir
   Open the frunk and remove the frunk liner/tub fasteners as needed to expose the washer reservoir fill neck and pump area. The reservoir on the 2024 Model Y is located on the passenger side and extends down behind the fender liner. Use a plastic trim tool to release push-pin clips without breaking them.
2. 2

   Drain or siphon the washer reservoir
   If the reservoir contains fluid, siphon it out through the fill neck into a clean container (fluid can be reused if not contaminated), or be prepared to catch up to ~3.5 qt with a drain pan when the pump is pulled. Draining first is strongly recommended to avoid a mess.
   ⚠Washer fluid is slippery and can be a slip hazard on shop floors. Clean spills immediately.
3. 3

   Locate and access the pump
   The washer pump is press-fit into a rubber grommet on the side of the reservoir, accessed from behind the front passenger-side fender liner area. You may need to partially release the wheel-well liner or a small access panel to reach it. Turn the steering wheel to gain working clearance if needed.
4. 4

   Disconnect the electrical connector
   Depress the locking tab on the pump's electrical connector and pull it straight off. Inspect the connector pins for corrosion or washer fluid intrusion — clean and dry if necessary.
5. 5

   Disconnect the washer hose
   Carefully pull the washer supply hose off the pump outlet. Be ready for residual fluid. Inspect the hose end — if it is split or hardened, trim it back slightly or replace as needed.
6. 6

   Remove the pump from the reservoir
   Grasp the pump body and pull straight out of the rubber grommet with a slight twisting motion. Fluid remaining in the reservoir will drain through the grommet bore — keep the drain pan in position. Inspect the grommet for tears, swelling, or hardening; replace if compromised.
   ⚠Do not pry the pump out with metal tools — you can tear the grommet or crack the reservoir.
7. 7

   Install the new pump
   Lubricate the new grommet (if replacing) and pump inlet stem lightly with fresh washer fluid — do NOT use petroleum grease, which will swell the rubber. Press the new pump straight into the grommet until fully seated. Verify it is square and not cocked in the bore.
8. 8

   Reconnect hose and electrical connector
   Push the washer supply hose fully onto the pump outlet until it bottoms out. Reconnect the electrical connector and verify the locking tab clicks into place.

Reassembly

1. Reinstall any wheel-well liner clips, frunk tub fasteners, and trim panels removed during access. Replace any clips that broke during removal.
2. Refill the washer reservoir with Tesla-approved windshield washer fluid (capacity ~3.5 qt). Do not use straight water in freezing climates.
3. Reconnect the 12V low-voltage battery. Torque the terminal per Battery Terminal Bolts spec — do not overtighten.
4. Close the frunk and verify it latches normally.

Verification

• Power on the vehicle. From the touchscreen Controls menu, activate the windshield washers (or use the stalk/steering button as equipped on 2024 Model Y) and confirm fluid sprays from both nozzles with normal pressure.
• Run the washers for 5–10 seconds and check under the frunk liner around the pump grommet for any leaks.
• Check that no washer fluid warnings appear on the instrument display, and that the level reads correctly after fill.
• Cycle the rear washer (if equipped) — note that the same pump typically feeds front and rear via a directional pump or separate circuit; confirm both functions on this vehicle.
• Recheck the pump area for leaks after the first drive cycle when fluid has had time to migrate.
