Door Weatherstrip

Replace the door weatherstrip (door seal) on a 2012 Tesla Roadster. The Roadster is built on the Lotus Elise platform, so the weatherstrip is a press-fit/clip-retained rubber seal around the door opening — no major disassembly required.

Tools required

Parts

• Door weatherstrip seal (Roadster-specific, often shared with Lotus Elise) × 1 — OEM Tesla Roadster or equivalent Lotus Elise door seal — verify fitment before ordering
• Replacement trim clips (as needed) × 1 — Generic push-in trim clip, replace any broken on removal

Preparation

1. Park on level ground, place in P (or in gear for manual-equipped early Roadsters), 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 low-voltage battery. On the 2012 Roadster, the 12V auxiliary battery is located in the front trunk area — refer to the owner's manual for exact location and disconnect sequence.
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. Work in a shaded area or indoors — direct sun makes new rubber weatherstrips overly soft and existing adhesive harder to clean.
7. Open the door fully and support it; avoid leaning on the door card during the job.
8. Inspect the new weatherstrip for the correct profile, drain holes (if any), and orientation marks before beginning removal.

Procedure

1. 1

   Inspect existing weatherstrip routing
   Before removing anything, photograph the existing weatherstrip path around the door aperture. Note any joints, seams, terminations at the A-pillar/sill/B-pillar area, and how the seal interfaces with the convertible top seal. The Roadster has a relatively short door, but seal orientation is critical for water management.
2. 2

   Identify retention method
   Roadster door weatherstrips are typically retained by an integrated U-channel that grips a flange around the door opening, sometimes supplemented with adhesive at corners and a few push-in clips. Run a finger along the seal to feel for any hidden fasteners or clip locations before pulling.
3. 3

   Remove any adjacent trim that overlaps the seal
   If sill plate trim, A-pillar trim, or interior B-pillar trim overlaps the weatherstrip ends, gently release these using plastic trim tools. Replace any broken trim clips on reassembly — do not reuse damaged clips.
   ⚠Roadster interior trim is fragile and replacement parts are difficult to source. Pull straight out at clip locations only.

4. 4

   Remove the old weatherstrip
   Starting at one corner (typically the lower rear), grip the seal firmly and pull the U-channel off the body flange progressively around the entire door opening. Work slowly through corners. If sections are bonded, use a plastic tool to break the adhesive bond — do NOT use a metal scraper against painted or composite surfaces.
   ⚠Do not yank with excessive force near the A-pillar/windshield area; the bond there can lift paint or composite material.
5. 5

   Clean the body flange
   Using isopropyl alcohol on a clean rag, thoroughly clean the body flange where the new seal will mount. Remove all old adhesive residue, dirt, and debris. Inspect the flange for corrosion, damage, or any deformation that would prevent the new seal from seating properly.
6. 6

   Inspect drain paths and door shut surfaces
   With the seal removed, inspect drain holes in the lower door frame and rocker area for blockages. Clear any debris. Also inspect the door's mating surface for cleanliness — old grime here causes premature seal wear.
7. 7

   Test-fit the new weatherstrip
   Lay the new seal around the door opening without pressing it on, confirming length, joint location, and any molded corners align with the body. Most Roadster door seals have a specific orientation — note any locating tabs or molded bends.
   ℹ️If the new seal is even slightly too long or short, stop and verify the part number — do not stretch or compress to force fit.
8. 8

   Install the new weatherstrip
   Begin installation at the manufacturer-indicated start point (often a molded corner or marked location). Press the U-channel firmly onto the body flange, working progressively around the opening. Use a soft rubber mallet only if necessary, tapping lightly through a clean rag — never strike directly on rubber or paint.
9. 9

   Seat corners and joints
   Pay particular attention to corners — these are the most common leak points. Ensure the seal is fully seated with no gaps and the lip orientation faces the door (not the body). If the original used adhesive at any point, apply manufacturer-specified weatherstrip adhesive sparingly at those same locations.
10. 10

    Verify door closure
    Carefully close the door. It will feel tighter than before due to the new uncompressed seal. Check that the door latches fully on the first attempt without slamming. If the door will not close or requires excessive force, re-open and verify seal seating before forcing it.
    ⚠Do not slam the door to overcome a misseated seal — this can damage the latch, striker, or hinge alignment.

Reassembly

1. Reinstall any sill plate, A-pillar, or B-pillar trim that was removed, using new trim clips where any were damaged. Torque any trim fasteners per the verified spec.
2. Reconnect the 12V low-voltage battery.
3. Cycle the door several times to allow the new seal to take a set.
4. Apply a light coat of silicone rubber protectant to the new seal surface to extend life and prevent sticking to the painted door edge.

Verification

• Visual check: seal is fully seated all the way around with no gaps, lifted sections, or twisted lips.
• Door closure: door latches with normal effort on first attempt and sits flush with surrounding bodywork.
• Water test: with the door closed, spray water around the door perimeter using a garden hose (not a pressure washer) and check the interior door card edge, sill, and footwell for any intrusion.
• Wind noise test: drive at highway speed and listen for whistles or rush noise around the door perimeter — most common at the upper A-pillar and B-pillar areas on the Roadster.
• Re-inspect after one week of use; new seals can shift slightly as they conform to the body flange.
• Note: The Roadster has no scheduled interval for weatherstrip replacement, but inspect annually given the age of all 2012 vehicles. Also a good time to confirm brake fluid (2-year interval) and any other deferred service items are up to date.
