🔧 Introduction to Mazda CX-5 Side Mirror Repair

The video begins with an introduction to a common issue with the Mazda CX-5's side mirror, which stops retracting. This problem, attributed to gear failure within the mirror mechanism, is described as a classic fault for this model. The presenter outlines the initial diagnostic, mentioning that the repair typically involves replacing several parts excluding the mirror itself, with costs amounting to roughly 30,000 yen including labor. However, the focus of this video is on a cost-effective repair solution using an unspecified part not listed in the parts catalog. The presenter then proceeds to dismantle the mirror, starting with the removal of the mirror glass, which is particularly challenging due to the cold weather making the parts brittle. The video emphasizes the care taken to avoid breaking the expensive mirror glass and the subsequent steps of carefully removing the cover and indicator to avoid further damage and additional costs.

🛠 Dismantling and Identifying the Problem

The presenter continues with the disassembly process by removing the mirror's housing and motor, highlighting differences between early and late model parts that complicate the repair. Despite these challenges, there is a determination to proceed with the repair using a hidden part not originally intended for this repair. The discovery that the motor part used in the previous models differs from the one in the later models prompts a more in-depth exploration. The presenter then focuses on extracting and examining the faulty gear causing the malfunction. Initial attempts to simply replace the damaged gear prove unsuccessful, leading to the decision to disassemble the entire motor assembly to address the issue directly.

🔨 Repairing and Reassembling the Motor

After dismantling the motor, the presenter finds the problematic gear and attempts a repair by sourcing a similar gear from a new motor, hoping for compatibility. The video demonstrates the meticulous process of disassembling the new motor to harvest the needed gear. Fortunately, the gears from the new motor match, allowing for a successful transplant. The repair process is likened to rebuilding, where the outer case of the motor remains the same, but the internals are replaced with new components. The presenter emphasizes the careful reassembly of the motor and the use of a vise to securely fasten the components, ensuring the motor functions correctly with the new parts.

🚗 Final Assembly and Operational Testing

The final stages of the repair involve reattaching the motor to the mirror base and conducting operational tests to ensure everything functions correctly. The presenter meticulously reconnects the wiring, secures the mirror to its base, and performs a final tightening of the screws. After confirming the mirror's retracting function works flawlessly, the reassembly is completed by reconnecting all the couplers and carefully installing the mirror glass to avoid damage. The video concludes with the presenter reflecting on the challenges faced due to initially incorrect part assumptions but ultimately showcasing a successful repair. The effort contrasts the presumed simplicity of the task with the actual complexity and satisfaction derived from overcoming unexpected challenges. The video ends with gratitude expressed to the viewers and an invitation to subscribe to the channel for future updates.

Keywords

💡Mazda CX-5

The Mazda CX-5 is a model of car mentioned in the video, specifically being the subject of a common repair issue. It is a compact SUV manufactured by Mazda, known for its reliability, style, and driving dynamics. In the context of the video, the Mazda CX-5 experiences a malfunction with its side mirror, which fails to retract. This problem serves as the central theme of the video, guiding the viewer through the diagnosis and repair process of this specific vehicle component.

💡Side mirror retraction failure

Side mirror retraction failure refers to the issue where the vehicle's side mirror does not fold inwards as intended. This problem is highlighted in the video as a common fault with the Mazda CX-5. The failure is attributed to the internal gears within the mirror's folding mechanism spinning freely without engaging, preventing the mirror from retracting. The video uses this malfunction to explain the troubleshooting and repair process, emphasizing the need for careful disassembly and repair to avoid additional damage.

💡Gear

A gear is a rotating machine part having cut teeth or, in some cases, inserted teeth (known as cogs), which mesh with another toothed part to transmit torque. In the video, the failure of the side mirror to retract is diagnosed as a problem with the gears inside the mechanism. The gears are supposed to engage and drive the retraction motion but are found to be freely spinning (empty rotation), indicating wear or a design flaw. This diagnosis leads to the exploration of a repair solution that involves replacing or fixing the faulty gear.

💡Disassembly

Disassembly refers to the process of taking apart a machine or structure to diagnose a fault or perform a repair. The video extensively covers the disassembly of the Mazda CX-5's side mirror to address the retraction failure. This process includes removing the mirror glass, the cover, and finally accessing the internal motor and gears. The careful disassembly is crucial to avoid damaging the delicate parts like the mirror glass and the cover's clips, which can add to the repair costs.

💡Motor

In the context of the video, the motor refers to the electric motor used to retract the side mirror. The motor is a key component of the mirror's folding mechanism, driving the gears that in turn fold the mirror. The discovery that the motor assembly differs between the early and later models of the CX-5 highlights the challenges of automotive repairs, such as the need for specific parts and the potential for unexpected complications.

💡Rebuild

Rebuild in the video refers to the process of repairing the side mirror by using parts that are not originally listed for the model being worked on, essentially refurbishing the malfunctioning unit with functional parts from a different source. This is demonstrated by disassembling a new motor to use its gears in the faulty assembly, illustrating a cost-effective repair strategy that avoids the high cost of complete part replacement.

💡Torx screws

Torx screws are a type of screw characterized by a six-point star-shaped pattern on the head, requiring a special Torx screwdriver to remove or tighten. The video mentions the use of Torx screws to secure the mirror assembly to the vehicle. This detail underscores the importance of having the right tools for vehicle repairs, as specialized screws like Torx are commonly used in automobiles to ensure secure fastening of components.

💡Wiring harness

The wiring harness refers to the assembly of electrical wires and connectors that transmit signals and electrical power within the vehicle. In the repair process detailed in the video, the wiring harness needs to be carefully disconnected and reconnected to remove the mirror assembly without damaging the electrical connections. This step is crucial for maintaining the functionality of the mirror's electronic components, such as the turn signal and the anti-fog heating element.

💡Paint and labor costs

Paint and labor costs are mentioned as significant factors in the repair process. The video highlights the potential for high expenses due to the need for painting parts like the mirror cover if damaged during disassembly, as well as the labor involved in the meticulous repair process. These costs contribute to the overall expense of the repair, motivating the DIY approach taken in the video to minimize expenses by avoiding damage and using alternative repair methods.

💡DIY repair

DIY repair, or Do-It-Yourself repair, refers to the approach taken in the video where the vehicle owner undertakes the repair process themselves to save on costs. The video provides guidance on how to perform the repairs, emphasizing the importance of having the right tools and knowledge to successfully complete the task.
