Review MAZDA Jdm Rx-7 Rx7 Windshield Wiper Motor Assembly Oem Rhd fits TURBO 1990

The **Mazda 849100-4670 JDM 1990 RX-7 FC3S Turbo Windshield Wiper Motor** is a meticulously crafted, high-performance component designed exclusively for the legendary **Fujitsu-Canon (FC3S) generation RX-7**, a car renowned for its precision engineering, lightweight construction, and exhilarating driving dynamics. This wiper motor is a direct-fit replacement for the stock unit, ensuring seamless integration with the original wiring harness, linkage, and mounting points, while delivering superior reliability and durability. Built to withstand the demands of both daily driving and spirited track use, this motor features a robust **brushless DC design**, which eliminates the wear and friction associated with traditional carbon brushes, resulting in longer operational life and reduced maintenance. The FC3S model is particularly sought after by enthusiasts for its **turbocharged 13B engine**, and this wiper motor is engineered to perform flawlessly under varying environmental conditions, from extreme temperatures to high humidity, ensuring crystal-clear visibility even during intense driving sessions. Whether you're restoring a show-quality RX-7 or upgrading an existing vehicle for enhanced performance and longevity, this **OEM-specification part** guarantees a perfect balance of authenticity and modern reliability. Its compact yet sturdy construction aligns with Mazda s signature attention to detail, making it an essential component for any owner seeking to maintain the RX-7 s iconic blend of sportiness and sophistication.

### Pros and Cons of Buying a 1990 Mazda RX-7 FC3S (JDM) Windshield Wiper Motor (Part Number: 849100-4670)

1. **Authentic Fit and Function** This is an original Mazda part designed specifically for the FC3S model, ensuring a perfect fit and reliable performance. Aftermarket parts may not always match the original specifications, leading to potential issues like misalignment or inconsistent operation.

2. **Durability and Longevity** Mazda parts, especially those from the 1990s, were built to last with high-quality materials. The wiper motor is likely to be robust and resistant to wear, provided it hasn t been neglected or damaged over the years.

3. **Ease of Installation** Since it s an OEM (Original Equipment Manufacturer) part, installation should be straightforward if you have basic mechanical skills or access to a mechanic. No modifications or adapters are typically required.

4. **Reliability for Classic Cars** For enthusiasts restoring or maintaining a classic RX-7, using genuine Mazda parts helps preserve the vehicle s authenticity and ensures compatibility with other systems (e.g., wiring, linkages).

5. **Potential for Resale Value** If you re restoring or selling the car later, having original or high-quality replacement parts can appeal to purists and collectors, potentially increasing the vehicle s value.

6. **Compatibility with JDM Modifications** If you ve made JDM-specific modifications (e.g., aftermarket interiors, performance upgrades), this OEM part will integrate seamlessly without risking compatibility issues.

1. **Age and Wear** The part is over 30 years old, which means it may show signs of wear, such as dried-out seals, corroded contacts, or a motor that no longer spins smoothly. Testing the motor before purchasing is crucial.

2. **Availability of Used Parts** While this part is common for RX-7s, finding a fully functional used unit may require searching through multiple sources (eBay, junkyards, or specialty forums). You might end up paying a premium for a rare, working example.

3. **Potential for Hidden Damage** Even if the motor appears to work, internal components like brushes, bearings, or the gear mechanism could be degraded. Without a thorough inspection or test drive, you risk buying a faulty unit.

4. **Cost Compared to Aftermarket Alternatives** Genuine Mazda parts can be expensive, especially for older models. Aftermarket wiper motors (e.g., from brands like ACDelco, Denso, or specialized JDM suppliers) may offer similar performance at a lower cost.

5. **Mismatched Condition with the Rest of the Car** If the rest of the RX-7 is in poor condition, replacing just the wiper motor won t significantly improve the vehicle s overall functionality or drivability. This purchase may be a minor upgrade in a larger restoration project.

6. **Risk of Counterfeit Parts** On platforms like eBay or Alibaba, there s a chance of receiving a replica or counterfeit part that doesn t meet Mazda s standards. Always verify the seller s reputation and ask for proof of authenticity (e.g., original packaging, Mazda part numbers).

Buying a 1990 Mazda RX-7 FC3S windshield wiper motor (part #849100-4670) is a practical choice if you prioritize authenticity, reliability, and ease of installation. It s ideal for enthusiasts who want to maintain the car s original integrity or are restoring it to showroom condition. However, the part s age and potential hidden flaws mean you should inspect it thoroughly (or test it in the car) before purchasing.

If cost is a concern or you re unsure about the motor s condition, an aftermarket alternative might be a safer bet. Always weigh the pros and cons against your specific needs whether you re restoring a daily driver, a project car, or a collector s vehicle.

- **If restoring or maintaining an RX-7 for authenticity:** Proceed with caution. Buy from a trusted source (e.g., a reputable junkyard, RX-7 specialist, or verified seller) and test the motor before finalizing the purchase.

- **If on a budget or unsure about condition:** Consider a high-quality aftermarket wiper motor (e.g., Denso or ACDelco) that matches the OEM specifications. These are often cheaper and come with warranties.

- **For immediate use:** Request a functional test of the motor (e.g., spin it by hand or test it in the car) to ensure it works before buying. Avoid purchasing sight-unseen unless you re confident in the seller s integrity.

Ultimately, the decision depends on your priorities whether you value originality over cost or are willing to compromise for reliability and affordability.
