2021-2025 Ford Bronco Rear Door: Decoding Part Numbers and the Child Lock Recall

Critical Compatibility Warning: 4-Door Full-Size Bronco ONLY

Known Issues, Recalls, and Technical Service Bulletins (TSBs)

While the door itself is a simple structural part, its components and integration with the body have been the subject of several factory communications.

Safety Recall: Malfunctioning Rear Child Lock (2025 Models)

NHTSA Recall No. 25V397 (Ford No. 25S64): Ford issued a recall for approximately 27,768 model year 2025 4-door Bronco vehicles due to a faulty child safety lock on the left-hand (driver's side) rear door. Due to a manufacturing defect causing components inside the door to interfere with the latch mechanism, the child lock can fail to engage even when it is in the 'ON' position. This could allow a rear passenger, such as a child, to open the door from the inside while the vehicle is in motion, increasing the risk of injury. Dealers will inspect and replace the left-hand rear door latch assembly free of charge. When purchasing a used 2025 model or a used door from one, it is critical to verify if this recall work has been completed.

Common Problems & TSBs

• Wind Noise: A frequent complaint from owners involves excessive wind noise, often from the rear passenger door area, at highway speeds on both hard and soft top models. This is often caused by poor alignment of the frameless window glass against the upper weatherstrip. A DIY fix involves removing the interior door panel and adjusting the window track's pitch to create a tighter seal. In other cases, dealers have replaced door seals to resolve the issue.
• Water Leaks: While most documented water leak TSBs (like TSB 22-2074) point to the A-pillars and windshield header area, body and seal integrity is a known concern for this generation. A poorly aligned or damaged rear door can also be a source of water intrusion.
• Window Operation: TSB SSM 50005 notes that the side door window may catch on the upper weatherstrip, making the door difficult to open. This is typically an alignment issue with either the door or the window glass itself.

Symptoms of a Failing or Damaged Rear Door

Unlike mechanical parts, a door assembly's failure is usually visible or audible. The most common reason for replacement is collision damage.

• Visible Damage: Dents, deep scratches, or creases from an accident are the most obvious signs. A bent door frame may be impossible to repair and will prevent proper sealing.
• Difficulty Closing or Latching: If the door doesn't close smoothly or requires slamming, the hinges may be sagging or the door/latch is misaligned from an impact.
• Excessive Wind or Road Noise: A sudden increase in noise from a specific door points to a sealing issue. This could be a warped door frame, misaligned window, or compressed weatherstripping.
• Water Leaks: Damp carpets or visible water drips around the door frame after rain or a car wash indicate a bad seal, which could stem from a poorly aligned door.
• Child Lock Failure (2025 models): The inability of the driver's side rear child lock to function is a direct symptom of the recall issue.

Buying a Used Dr Assm, Rear Side: What to Check

Purchasing a used OEM door is an excellent way to save money, especially since aftermarket shells are not widely available. However, you must be a careful shopper. Here’s your inspection checklist:

1. Confirm the Model: Re-verify it came from a 4-Door full-size Bronco, not a Bronco Sport. Ask the seller for the VIN of the donor vehicle if possible.
2. Ask What's Included: This is the most important question. A 'door assembly' can mean different things. Is it a bare shell, or does it include the window glass, window regulator (motor), wiring harness, exterior handle, interior trim panel, and speaker? The price should reflect what's included. A bare shell will require you to transfer all components from your old door.
3. Inspect for Hidden Damage: Look for ripples in the paint or mismatched textures, which indicate previous bodywork. Carry a small magnet; it will not stick to areas with thick plastic body filler (Bondo).
4. Check the Seams: Examine the factory seams along the bottom and edges of the door. Flaking paint or swelling can be a sign of rust starting from the inside out.
5. Verify Straightness: Lay the door on a flat surface or look down its length from the front and back edges. Check for any twisting or bowing that would indicate it was from a vehicle with frame damage.
6. Match the Paint: If buying a painted door, get the paint code from the seller and match it to the code on your vehicle's door jamb sticker to avoid the cost of a full respray.

Cost Comparison for a Rear Door Replacement

Prices can vary significantly based on what components are included with the door assembly. Labor costs increase if a technician has to transfer glass, wiring, and internal mechanisms from the old door to the new shell.
