Replacement of a door weatherstrip (door-mounted primary seal) on a 2024 Tesla Model S Plaid. This is a non-electrical trim job, but the door contains the presenter motor, speakers, and harness, so care is needed near the door edge and B-pillar.

Warnings

Tools required

Parts

• OEM door weatherstrip (door-mounted primary seal) — model/door specific × 1 — Tesla Model S (2021+ refresh) door weatherstrip — verify left/right and front/rear by VIN
• Replacement trim clips (if any are damaged on removal) × 1 — Manufacturer-specified trim clips

Preparation

1. Park on level ground, place in P, 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. Disconnect the 12V (or 16V lithium, if equipped — located under the rear seat on some 2021+ Plaid units; otherwise under the frunk nose cowl) low-voltage battery.
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. Verify the correct replacement seal by VIN — front and rear doors use different parts, and left/right are not interchangeable.
7. Open the affected door fully and support it (it will not auto-index the glass with 12V disconnected).
8. Clean the door edge / aperture flange with isopropyl alcohol so the new seal seats cleanly.
9. Lay down a fender cover or soft towel on the rocker to protect paint during removal.

Procedure

1. 1

   Identify the failed seal
   Confirm whether the leak/wear is on the door-mounted weatherstrip (attached to the door's outer perimeter) or the body-side aperture seal. This procedure covers the door-mounted seal. If both are damaged, order both parts.
2. 2

   Inspect retention method
   Tesla Model S door weatherstrips are retained by a combination of a press-fit U-channel over the door flange and, in some areas, push-pin clips or factory adhesive at the corners. Visually trace the seal around the entire door perimeter and note any clip locations before removal.
3. 3

   Begin seal removal at a corner
   Starting at a lower corner (typically the front-lower corner of the door), gently grasp the seal and pull it away from the door flange. Work slowly with steady, even tension. If resistance is encountered, use a plastic trim tool to release a clip — do not yank.
   ⚠Do not use a metal pry tool against the painted aluminum door edge — it will dent or chip paint instantly.
4. 4

   Work the seal off the full perimeter
   Continue peeling the seal from the door flange around the entire perimeter. Note the orientation — the drainage lip faces downward/outboard. Take a photo before fully removing, for reference during install.
5. 5

   Release any adhesive sections
   At corners or transitions, the seal may be bonded with factory adhesive. Warm with a heat gun on low (only if needed), then peel slowly. Do not stretch the old seal aggressively — once detached, discard it; it cannot be reused.
   ⚠Excessive heat on the painted aluminum door skin can damage the paint clear-coat. Keep the heat gun moving and below 60 °C surface temp.
6. 6

   Clean the door flange
   Remove all adhesive residue and dirt from the door flange using a plastic scraper and isopropyl alcohol. Inspect the flange for damage, corrosion, or sealer breaches. Any bare aluminum should be touched up before installing the new seal.
7. 7

   Inspect retention clips
   Check any push-pin clips or retention features on the door for damage. Replace any broken clips before installing the new seal. Trim clips that crack on removal must be replaced — do not reuse.

8. 8

   Test-fit the new weatherstrip
   Without removing any factory adhesive backing, lay the new seal around the door perimeter and confirm the orientation: drain lip down/outboard, joint (splice) location matching the original (typically at the bottom of the door, hidden from view).
   ℹ️If the new seal is shipped coiled, allow it to relax at room temperature for 30+ minutes before installation to avoid memory kinks.
9. 9

   Install the new seal
   Starting at the splice/joint location (bottom of door), press the U-channel of the seal firmly onto the door flange. Work around the perimeter using hand pressure only, ensuring the seal is fully seated against the flange with no gaps. Engage any retention clips into their holes as you go. Do not stretch the seal — install it relaxed.
   ⚠Stretching the weatherstrip during install will cause it to shrink back over time, creating gaps at the corners and wind/water leaks.
10. 10

    Seat corners and adhesive sections
    If the new seal has adhesive-backed sections (typically corners), peel the backing only after confirming fitment, then press firmly for 30+ seconds per section. Use a soft mallet or hand pressure — never a steel hammer — to fully seat the U-channel along the entire flange.
11. 11

    Verify door closes correctly
    With 12V still disconnected, gently close the door by hand. The door should close with normal effort. If it requires excessive force, the seal is over-stuffed or misaligned — open and reseat. Do not slam an aluminum door against a new seal.

Reassembly

1. Reconnect the 12V (or 16V) low-voltage battery.
2. Allow the vehicle to wake and complete its boot sequence (touchscreen up, no warnings).
3. Open and close the door several times — the frameless window auto-index function should drop the glass slightly on opening and seat it on closing. Confirm the glass clears the new seal without binding.
4. Apply a thin film of silicone-safe rubber dressing to the new seal to extend life and reduce friction against the glass and body.

Verification

• Visually inspect the seal around the entire door perimeter — it should sit flat against the door flange with no lifted sections, gaps at corners, or twists.
• Close the door and run a dollar-bill test at multiple points around the perimeter — the bill should pull out with consistent, moderate resistance.
• Perform a low-pressure water test (garden hose, not pressure washer) along the top and sides of the door. Check the door sill, lower interior trim, and floor for any water intrusion.
• Drive at highway speed (60+ mph) with the cabin quiet and listen for new wind noise around the door perimeter — this confirms an acoustic seal as well as a water seal.
• Confirm the frameless glass auto-index function still operates correctly on door open/close — if the glass binds on the new seal, recheck seal seating at the upper door edge.
• Note: this job is not part of a Tesla scheduled maintenance interval, but it's a good time to also inspect the cabin air filter (Tesla recommends every 2 years, or 3 years for HEPA-equipped Model S) since you already have the 12V disconnected.
