Door Weatherstrip

Replace a worn or damaged door weatherstrip (door-mounted seal) on a 2024 Tesla Model S Long Range. This is a low-voltage, body-only job with no HV exposure, but care must be taken not to damage the painted aluminum door edge during removal.

Warnings

Tools required

Parts

• Door weatherstrip (door-mounted seal, position-specific: FL/FR/RL/RR) × 1 — Tesla OEM Model S 2024 door weatherstrip — order by door position and VIN
• Replacement retaining clips (if any are damaged on removal) × 1 — Manufacturer-specified weatherstrip clip

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 in the front trunk (frunk) under the nose cowl panel. (Note: 2021+ Plaid variants may use a 16V Li-ion unit under the rear seat — verify by trim 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. Identify which weatherstrip is being replaced (door-mounted vs. body aperture) and confirm the correct part for the specific door (FL/FR/RL/RR).
7. Open the affected door fully and support it so it cannot swing during the procedure.
8. Clean the door channel area with a soft brush to remove debris before removal.

Procedure

1. 1

   Inspect and document the existing weatherstrip
   Walk the full perimeter of the door-mounted weatherstrip. Note any retaining clip locations, adhesive sections, drain channel orientation, and the seam/joint location (typically at the bottom of the door). Photograph the install for reference.
2. 2

   Release the weatherstrip starting at the seam
   Locate the factory seam (bottom of door on most Model S doors). Using a nylon trim tool, gently lift the lip of the weatherstrip away from the door flange. Work slowly to feel for clips vs. adhesive sections.
   ⚠Do not use a metal pick or screwdriver against the painted door edge — aluminum dents and chips far easier than steel.
3. 3

   Walk the weatherstrip off the door flange
   Continue around the door perimeter, peeling the weatherstrip off the flange in one continuous motion where possible. For sections retained by push-in clips, pull straight out perpendicular to the flange — do not twist.
4. 4

   Release any adhesive-bonded sections
   On adhesive-bonded sections (commonly upper corners or near hinges), warm the area with body heat or a low-temp heat source if available, then peel slowly at a shallow angle. Do not use a heat gun on high — paint and adjacent plastic trim can be damaged.
   ⚠Excessive heat will damage paint and adjacent door trim. Keep any heat source moving and below ~120°F surface temp.
5. 5

   Remove residual adhesive and clean the flange
   Wipe the door flange with isopropyl alcohol on a microfiber cloth to remove old adhesive residue, dirt, and silicone. Inspect the flange for damage, paint chips, or corrosion (rare on aluminum but possible at fastener points). Allow to dry fully before installing the new strip.
6. 6

   Inspect retaining clips
   Check each clip location for broken or deformed clips left in the flange. Replace any damaged clips with the manufacturer-specified replacement before installing the new weatherstrip.
7. 7

   Dry-fit the new weatherstrip
   Position the new weatherstrip around the door, aligning the seam at its factory location and ensuring drain slots (if present) face downward. Confirm orientation before pressing any clips home.
   ⚠Weatherstrips are directional. Installing upside-down will block drains and cause water intrusion into the door cavity.
8. 8

   Seat the weatherstrip onto the flange
   Starting at the seam, press the weatherstrip channel onto the door flange using firm thumb pressure. Walk around the perimeter, seating clips with a direct push (you should feel each clip click in). Do not stretch the weatherstrip — it should follow the flange in its natural relaxed length.
9. 9

   Verify full perimeter seating
   Run a finger along the entire weatherstrip-to-flange interface. There should be no lifted sections, no gaps at the corners, and no twisted lip. Pay particular attention to upper corners and the area near the door latch.
10. 10

    Optional: apply rubber conditioner
    Lightly apply a rubber-safe silicone weatherstrip dressing to the seal contact face. This prevents sticking to the body aperture seal, especially in cold climates where Model S frameless doors can freeze shut.

Reassembly

1. Reconnect the 12V (or 16V) low-voltage battery and torque the terminal to OEM specification — refer to Tesla Service Manual.
2. Close the frunk and reinstall any cowl panels removed for battery access.
3. Wake the vehicle and allow window auto-index/door modules to re-initialize. On frameless-door Model S, fully open and close the door once with the vehicle awake so the window drop/raise function re-syncs against the new seal.
4. Verify door closes with normal effort — a too-stiff close indicates the weatherstrip is overstretched or misseated.

Verification

• Close the door at normal force and confirm it latches on the first attempt without slamming.
• From inside, visually confirm the weatherstrip compresses evenly against the body aperture with no visible gaps along the full perimeter.
• Spray the closed door with a garden hose (low pressure) along the upper and rear edges and check the door sill, lower carpet, and B-pillar interior for water intrusion.
• On a road test, listen for wind noise above 50 mph — a properly seated Model S door seal should be near-silent. Whistling indicates a lifted or twisted section, typically at the upper rear corner.
• Confirm window auto-index works correctly: window should drop slightly on door handle pull and seal up fully on door close. If it does not, cycle the door with the vehicle awake or perform a window calibration per Tesla Service Manual.
• This job is not on a Tesla scheduled service interval, but while the door is open, take the opportunity to inspect cabin air filter age (replace every 2 years, or every 3 years if HEPA-equipped) and 12V battery age (typical replacement at 3–5 years).
