Replace the windshield washer fluid pump on a 2024 Model X. The pump is mounted to the washer reservoir, which is accessed through the front trunk (frunk) area on the passenger side.

Warnings

Tools required

Parts

• Windshield washer pump (Model X) × 1 — OEM Tesla washer pump assembly — match by VIN
• Washer pump grommet/seal × 1 — Replace if torn or hardened — typically supplied with pump

Fluids

• Windshield Washer Fluid — 3.5 qt

Preparation

1. Park on level ground, place in P, engage the parking brake.
2. Exit ALL doors with the key fob taken at least several meters 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, then disconnect the 12V low-voltage battery located in the frunk (similar position to Model S). Tighten the terminal only to the verified spec on reassembly.
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. Identify the washer fluid reservoir fill neck in the frunk and trace it down to the reservoir body to plan access to the pump.
7. Have a drain pan and rags ready — washer fluid will spill from the pump port.

Procedure

1. 1

   Access the washer reservoir
   Remove the necessary frunk trim panels and any wheel-well access cover required to reach the side of the washer reservoir where the pump is mounted. Use plastic trim tools to release push-pin clips. Set hardware aside in order.
2. 2

   Drain or lower fluid level (optional but recommended)
   If the reservoir is more than partially full, siphon fluid out through the fill neck into a clean container to minimize spillage when the pump is removed. Washer fluid is the only fluid in this circuit (3.5 qt capacity).
3. 3

   Locate the washer pump
   Identify the pump pressed into the lower side of the reservoir. It will have a single electrical connector and one or two outlet hoses (windshield, and on some configurations a rear/headlight washer feed).
4. 4

   Disconnect electrical connector
   Depress the locking tab and unplug the pump's electrical connector. Inspect terminals for corrosion or melting; if present, address wiring harness damage before installing a new pump.
   ⚠Confirm the 12V battery is disconnected before unplugging the pump to avoid shorting the connector against the body.
5. 5

   Disconnect washer hose(s)
   Carefully pull the washer hose(s) off the pump outlet barb(s). Expect a small amount of fluid to weep. Cap or plug hoses with a clean rag to keep debris out.
6. 6

   Remove the pump from the reservoir
   Grasp the pump body and pull straight outward with a gentle twisting motion. The pump is retained by a rubber grommet pressed into the reservoir wall. Position the catch pan directly below — fluid will drain from the port as the pump comes free.
   ⚠Do not pry between the pump and the reservoir with a screwdriver — you can crack the reservoir, which is a much larger repair.
7. 7

   Inspect and transfer the grommet
   Inspect the rubber grommet in the reservoir port. If it is torn, hardened, or distorted, replace it. A compromised grommet will leak washer fluid into the frunk area.
8. 8

   Install the new pump
   Lubricate the new pump's seal area lightly with fresh washer fluid (no grease — it can swell the rubber). Align the pump and press it straight into the grommet until fully seated. Confirm it is square to the reservoir.
9. 9

   Reconnect hoses and electrical connector
   Push washer hose(s) fully onto the outlet barb(s) until they bottom out. Reconnect the electrical connector until the lock clicks. Verify the connector is fully seated.

Reassembly

1. Reinstall any wheel-well access panel and frunk trim panels removed for access; seat all push-pin clips fully.
2. Top up the washer reservoir with windshield washer fluid (system capacity ~3.5 qt). In freezing climates, use a winter-rated fluid — do not use plain water, which can freeze and damage the pump and lines.
3. Reconnect the 12V low-voltage battery in the frunk. Torque the battery terminal hardware per the verified spec.
4. Close the frunk and verify it latches properly.

Verification

• Power up the vehicle (driver in seat, brake pressed) and allow the touchscreen to fully boot.
• From the wiper stalk/controls, activate the windshield washer. Confirm fluid sprays from both nozzles within 1-2 seconds and that the wipers cycle through the wash routine.
• If equipped, also verify any rear/headlight washer function depending on the pump configuration.
• Inspect the pump-to-reservoir grommet, hose connections, and the area beneath the reservoir for any drips after several wash cycles.
• Clear any related washer/wiper alerts from the touchscreen if present, and confirm no new alerts appear after a short drive.
• Note: while you are in this area, this is a good time to check cabin air filter age (Tesla recommends every 2 years, or every 3 years on HEPA/Bioweapon Defense-equipped Model X) and confirm the 12V battery's age — typically 3-5 years service life.
