Replace a door weatherstrip (door-mounted primary seal or body-side secondary seal) on a 2024 Model Y Performance. This is a non-electrical, non-HV trim job, but care is required around painted aluminum body panels and the frameless window glass.

Warnings

Tools required

Parts

• Door weatherstrip (door-mounted or body-side, as applicable) × 1 — Tesla Model Y 2024 OEM weatherstrip — verify by door (FL/FR/RL/RR) and position (door-mounted vs body-aperture)
• Replacement retention clips (if original clips deform on removal) × 1 — OEM-spec weatherstrip clips

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 (located under the rear seat / rear cargo area trim area on 2024 Model Y — refer to architecture notes). This prevents the frameless window from auto-dropping/raising while the door is being worked on.
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 which weatherstrip is being replaced: (a) door-mounted primary seal that runs around the perimeter of the door, or (b) body-side secondary seal that runs around the door aperture on the body. The removal procedure differs slightly.
7. Clean the surrounding paint with isopropyl alcohol and apply painter's tape along the door aperture / door edge to protect paint during removal.
8. Lay out new weatherstrip in a warm area (or gently warm with a heat gun) so it relaxes and conforms to the contour during installation.

Procedure

1. 1

   Open door and support weight
   Open the affected door fully. With the 12V disconnected the door check strap still functions normally. Do not let the door free-swing during the procedure — wind gusts can stress the hinges.
2. 2

   Identify seal retention method
   Inspect the existing weatherstrip. Tesla weatherstrips on the Model Y are typically retained by a combination of a continuous rubber lip that grips a pinch-weld flange, integrated push-in clips at corners, and in some locations adhesive. Locate the clip positions before pulling.
3. 3

   Release one corner to start
   Starting at a lower corner (front-lower for a door-mounted seal, or A-pillar base for a body-side seal), grip the seal firmly and pull straight off the flange with steady even force. Use a nylon trim tool to release any push-in clips — do not use a metal pry bar against painted aluminum.
   ⚠Pull perpendicular to the flange — angled pulls can tear the seal flange and leave rubber stuck on the pinch-weld.
4. 4

   Work the seal off progressively
   Walk the seal off the flange in 6–12 inch increments. At adhesive sections, work a plastic tool under the seal to break the adhesive bond. If clips remain stuck in the body, remove them with the nylon tool and inspect — replace any that are deformed.
5. 5

   Inspect and clean the flange
   Once the seal is off, inspect the pinch-weld flange and surrounding paint for damage, corrosion, or residual adhesive. Clean the entire flange with isopropyl alcohol and a microfiber towel. Allow to fully dry before installing the new seal.
   ℹ️If you see bare metal or paint chips, address with touch-up before installing the new seal — moisture trapped under the seal will corrode aluminum body panels.
6. 6

   Dry-fit the new weatherstrip
   Align the new weatherstrip with its drain holes (if any) facing downward and any molded corners matching the door/body geometry. Confirm orientation before pressing on — Tesla seals are directional and have specific corner radii for the front vs. rear of the door.
7. 7

   Seat the new seal at clip locations first
   Press the new seal onto the flange at the clip locations first (typically corners). You should feel/hear each clip snap home. Then walk the seal onto the flange between clips using firm hand pressure — do not use a hammer or mallet.
   ⚠Aluminum body — do not strike with hammer. Use only hand pressure or a soft rubber roller.
8. 8

   Verify continuous seating
   Run a finger along the entire length of the seal to confirm the rubber lip has fully engaged the flange with no lifted sections. Pay special attention to upper corners where the frameless glass contacts the seal.
9. 9

   Apply rubber conditioner (optional)
   Lightly apply silicone-safe rubber lubricant to the contact surface where the door glass or body meets the new seal. This prevents the seal from sticking to glass on cold mornings and reduces break-in noise.

Reassembly

1. Remove painter's tape from the paint.
2. Reconnect the 12V low-voltage battery and torque the battery terminal to OEM specification — refer to Tesla Service Manual.
3. Close all doors with the key fob present so the vehicle wakes and the window controllers can re-initialize.
4. Cycle the affected window fully down and fully up several times so the frameless glass re-learns its auto-index position against the new seal.
5. Verify auto-presenting door handles operate normally on the affected door.

Verification

• Visually confirm the seal is fully seated around the entire perimeter with no gaps, twists, or lifted sections.
• Close the door at normal effort (do not slam) — it should latch on the first detent without excessive resistance. A new seal will feel slightly stiffer for the first few days.
• Perform a water test: spray the door perimeter with a garden hose at low-to-medium pressure (not direct high-pressure wash) and check the door sill, kick panel, and headliner edge for any water intrusion.
• Drive at highway speed (60+ mph) and listen for new wind noise that wasn't present before — a properly seated Model Y seal should be quieter, not louder.
• Check that the frameless window drops ~10mm when the door handle is pulled and rises fully when the door closes. If the glass contacts the seal incorrectly, the window auto-index may need to be relearned via a full down/up cycle on the door switch.
• Confirm no Tesla touchscreen alerts are present related to door or window function after the 12V reconnect.
