Replacement of the front power window regulator on a 2024 Tesla Model 3 Performance. Requires removal of the front door trim panel, vapor barrier, and glass before unbolting the regulator/motor assembly from the door inner.

Warnings

Tools required

Parts

• Front door window regulator assembly (with motor) — left or right as applicable × 1 — Manufacturer-specified Model 3 front regulator (LH or RH)
• Replacement door trim panel clips (commonly damaged on removal) × 1 — OEM-spec door panel push clips
• Butyl/vapor barrier sealant (if vapor barrier is disturbed) × 1 — Generic automotive butyl rope sealant

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 low-voltage battery (located behind the right rear seat back panel on most 2024 Model 3; some 2024+ units use a lithium 12V under the floor — verify before opening trim).
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. Lower the window approximately 4-6 inches before disconnecting 12V to expose the regulator clamp bolts through the access holes (if accessible on this model). If already powered down, plan to access clamps through the inner door panel openings instead.
7. Have a helper available to support the glass when releasing it from the regulator carriers.
8. Lay out a padded surface near the vehicle to set the door panel and glass on once removed.

Procedure

1. 1

   Remove door trim panel fasteners
   Open the front door fully. Using a plastic pry tool, gently release the small trim cover behind the interior door pull/handle area to expose any hidden fasteners. Remove the visible Torx fasteners securing the door card to the inner door. Work along the lower and forward edges with a trim tool to release the perimeter clips.
   ⚠Pry only at clip locations to avoid cracking the door card or damaging the painted aluminum door skin.
2. 2

   Disconnect door panel and remove
   Lift the door card upward and outward. Tilt it to access the rear of the panel and disconnect the electrical connectors for the window switch pack, speaker, and any ambient lighting. Set the panel on a padded surface, exterior side up.

3. 3

   Peel back vapor barrier
   Carefully separate the plastic vapor barrier from the butyl sealant around the perimeter of the inner door. Peel only as much as needed to access the regulator and glass clamp bolts. Preserve the butyl rope on the door — do not let the barrier fold onto itself and stick.
   ℹ️If the butyl is damaged or the barrier tears, replace with new butyl sealant during reassembly to maintain the door's water management.
4. 4

   Secure and release the door glass
   With the window fully raised, secure the glass to the top of the door frame with strong painter's tape across the outer surface. Through the access holes in the inner door, locate the two glass-to-regulator clamp bolts. Loosen these bolts (do not fully remove unless required) so the glass releases from the regulator carriers.
   ⚠Confirm tape is fully supporting the glass before fully releasing the clamps. Frameless glass will drop into the door cavity and may shatter.
5. 5

   Remove the door glass
   Remove the painter's tape while supporting the glass by hand. Tilt the glass slightly and lift it straight up and out of the door. Set the glass flat on a padded blanket, away from the work area.
6. 6

   Disconnect window motor harness
   Locate the electrical connector at the window regulator motor. Release the locking tab and disconnect the harness. Free the harness from any clips along the regulator assembly.
7. 7

   Unbolt the window regulator assembly
   Locate the regulator mounting fasteners around the perimeter of the inner door (typically along the rails and at the motor mounting point). Support the regulator with one hand while removing the fasteners. Maneuver the regulator out through the largest access opening in the inner door.

8. 8

   Compare and prep new regulator
   Compare the new regulator assembly side-by-side with the original to confirm correct handing, motor connector orientation, and mounting hole pattern. Verify the carriers are at a position that will align with the glass clamp height before installation.
9. 9

   Install new regulator
   Maneuver the new regulator into the door cavity through the access opening. Align the mounting points and start all fasteners by hand before torquing. Torque to OEM specification — refer to Tesla Service Manual for the door regulator-to-door specification; if the manufacturer-specified bracket-style fasteners are used, torque per the verified bracket value.

    Reconnect motor harness
    Reconnect the electrical connector to the window motor until it clicks and locks. Reseat the harness into any retaining clips along the regulator.
11. 11

    Reinstall the door glass
    Lower the glass back into the door from above, aligning it with the regulator carriers. Seat the glass into the carrier clamps, then raise the glass fully and re-tape it to the door frame. Snug both clamp bolts evenly so the glass is centered front-to-back in the channel, then torque. Torque to OEM specification — refer to Tesla Service Manual for glass clamp bolts.

Reassembly

1. Re-adhere the vapor barrier to the door using existing butyl, adding fresh butyl sealant to any gaps. The barrier must be continuous to prevent water intrusion into the cabin.
2. Reconnect the door card connectors (switch pack, speaker, ambient lighting if equipped). Verify each connector clicks and locks.
3. Align the door card to the upper window-line clip rail first, then press the perimeter clips home with palm pressure — do not strike with a fist or mallet on the aluminum door.
4. Reinstall all door panel Torx fasteners and any trim covers.
5. Reconnect the 12V battery. Torque the terminal bolt.
6. Perform window auto-up/anti-pinch calibration: with the door closed and ignition on, fully lower the window using the switch and hold for 2 seconds past the stop, then fully raise the window and hold for 2 seconds past the stop. Repeat once. Confirm one-touch up/down works.

Verification

• Cycle the window fully up and down at least 5 times — listen for binding, scraping, or motor labor.
• Verify the glass seats fully against the upper seal at the top of travel and seals against the A-pillar and B-pillar when closed (Model 3 frameless glass auto-indexes slightly down when the door is opened and back up when closed — confirm this behavior works after calibration).
• Close the door and confirm no wind-noise or water-leak path; spray-test with a low-pressure hose along the upper seal and verify no water enters the cabin.
• Confirm anti-pinch reversal works by lightly obstructing the window during auto-up — it should reverse direction.
• Check the Tesla touchscreen for any door or window-related alerts; clear any transient codes that resulted from 12V disconnect.
• Note: while you have the 12V disconnected, this is also a good time to log the date for the 2-year brake fluid service interval and verify cabin air filter age (also a 2-year interval on Model 3).
