2007-2008 Honda Fit Front Door Guide: Recalls, Lock Actuators, and Rust

Critical Safety Warning: Power Window Master Switch Recall

Symptoms of a Damaged or Failing Front Door

Failures can originate from the door shell itself or from the many components housed within it. Here are the most common symptoms, broken down by part.

Symptoms Related to the Door Shell

• Visible Damage or Misalignment: Dents, deep scratches, or a bent frame from a collision are the most obvious signs of failure. A poorly aligned door will have uneven gaps around its perimeter, may be difficult to open or close, and can damage the latch or striker.
• Wind Noise or Water Leaks: If the door is not sealing correctly against the body, you will hear excessive wind noise at speed. Water leaks during rain are another clear indicator of a bad seal, which could be caused by a bent door frame or worn weatherstripping.
• Rust and Corrosion: Check the bottom edge and lower inside seam of the door. These areas can trap moisture and are common places for rust to start. Bubbling paint is the first sign of underlying corrosion.

Symptoms of Failing Internal Components

• Power Locks Behave Erratically: The door locks may lock or unlock by themselves, either while driving or when the car is off. This is often a symptom of the faulty power window master switch recall issue, as the switch contains the door lock controls.
• Grinding or Buzzing Noise When Locking/Unlocking: A loud buzzing, grinding, or clicking sound from inside the door when using the power locks points to a failing door lock actuator motor. The lock may also operate slowly or not at all.
• Power Window Won't Go Up or Down: If you hear the motor trying to work but the window doesn't move, or it moves slowly, crookedly, or makes grinding/popping noises, the window regulator (the mechanism that lifts the glass) has likely failed. If you hear no noise at all, the problem could be the motor, the switch, or a wiring issue.
• Door Won't Open from Inside or Outside: If the handles move but the door doesn't unlatch, a cable or rod connecting the handle to the latch mechanism may have broken or become disconnected. In some cases, the latch mechanism itself can seize.

Known Issues, Recalls, and TSBs for 2007-2008 Honda Fit

This generation of Honda Fit had several important issues related to the front doors and associated wiring.

• NHTSA Recall 13V260000 (originally 10V033000): This is the critical power window master switch recall mentioned above. Water intrusion can cause a fire hazard. The recall involves replacing the driver's master power window switch.
• NHTSA Recall 07V523000: On 2007 and some 2008 models, wire harness splices under the driver's side carpet were not sufficiently sealed. In areas where road salt is used, moisture could corrode the splices and cause a malfunction in the airbag's Occupant Detection System (ODS). This could lead to improper airbag deployment in a crash. The fix involves sealing the splices.
• Common Door Lock Actuator Failure: Outside of any recall, the door lock actuators on these vehicles are a very common failure item. Owners frequently report buzzing noises and locks that stop responding to the key fob or interior switch.

Buying a Used 2007-2008 Honda Fit Front Door: A Step-by-Step Inspection Guide

Purchasing a used OEM door is an excellent way to save money, but careful inspection is key. You will be buying a bare 'door shell', so you must transfer the internal components, glass, and trim from your old door.

1. Check for Rust: This is the most important check. Thoroughly inspect the bottom seam of the door, both inside and out. Use your fingers to feel for any bubbling under the paint, which indicates hidden rust. Also check around the window trim and mirror mount.
2. Look for Signs of Previous Repair: Examine the door's surface from an angle in good light. Look for waves in the reflection, which can indicate body filler (Bondo) from a past repair. Check for paint overspray on the weatherstripping or inside the door jamb.
3. Inspect the Frame Integrity: Look at the door's overall shape. Ensure it is not twisted or bent. Pay close attention to the hinge mounting points and the latch area to make sure they are not damaged or stressed.
4. Verify Compatibility: The main door shell is the same for Base and Sport trims on 2007-2008 models. All US models from these years were equipped with power windows. However, it's still wise to visually confirm you are buying a door for a power window vehicle.
5. Assess Minor Dents and Scratches: Small, shallow dents and surface scratches are often acceptable on a used door, as it will likely need to be repainted to match your vehicle anyway. A lower price should reflect this cosmetic damage.
6. Check the Wiring Harness: If the door includes the wiring harness, inspect the rubber boot that passes between the door and the car body. Look for any cracked, brittle, or cut wires, as this can save you from a future electrical headache.

Cost Comparison: New vs. Used Door Shells

The price of a replacement door varies significantly based on whether you buy new, used, and who does the labor. Remember that these prices are typically for the bare door shell and do not include paint, labor, or transferring of parts.

Installation Guide & Difficulty

• Difficulty Rating: 4 out of 5
• Estimated Time: 3-5 hours for a DIYer
• DIY Feasible: Yes, for an experienced DIYer. Not recommended for beginners.

Replacing a front door is a challenging job primarily because of the door's weight and the need for precise alignment. It is strongly recommended as a two-person job.

High-Level Steps:

1. Disconnect the battery.
2. Open the door and support its weight with a floor jack and a padded block.
3. Disconnect the electrical wiring harness at the kick panel and feed it out of the door. Disconnect the door check strap.
4. Remove the bolts securing the door hinges to the car's body. With a helper, carefully lift the door off the car.
5. Transfer all components from the old door to the new one: window glass, regulator, motor, lock actuator, latch, interior panel, exterior handle, and mirror.
6. With a helper, position the new door and loosely install the hinge bolts.
7. Carefully adjust the door's position to achieve even gaps all around and ensure it latches smoothly without slamming. This is the most difficult and time-consuming step.
8. Tighten the hinge bolts to spec, reconnect the wiring harness and check strap, and test all functions.
