### **Pros and Cons of buying a Mercedes-Benz 1669004304 (2013 2016 GL350/GL450 Right Seat Module)**
#### **Pros:**1. **Reliability of Mercedes-Benz Luxury Platform** The GL350 and GL450 (based on the ML platform) are known for their robust build quality, comfortable ride, and strong resale value compared to many competitors. The right seat module (part 1669004304) is a critical component for the rear passenger seating system, ensuring proper functionality of the rear seats, power adjustments, and heating/cooling controls.
2. **Aftermarket Availability** Mercedes-Benz parts, especially for the ML/GL series, have a strong aftermarket presence. This module is relatively common, meaning you can find replacements from authorized dealers, specialty shops, or online retailers (e.g., RockAuto, eBay, or local Mercedes specialists).
3. **Compatibility with Common Issues** The GL350/GL450 models (especially pre-facelift versions) are prone to electrical gremlins, seat motor failures, and wiring issues. Replacing the right seat module can resolve problems like:
- Non-functional power seat adjustments (recline, forward/backward).
- Malfunctioning seat heating or cooling.
- Erratic behavior in the seat control switches (e.g., intermittent power or no response).
- Compatibility with aftermarket seat covers or modifications.
4. **Potential Cost Savings vs. Full Seat Replacement** Replacing just the seat module (electronic control unit and wiring harness) is often cheaper than buying a complete rear seat assembly. This is a targeted repair rather than a full seat swap, which can be expensive.
5. **DIY Feasibility** While the installation requires some mechanical and electrical knowledge, many owners with basic automotive skills can replace the module themselves, saving labor costs. Tools needed include a socket set, wiring diagram access, and possibly a scan tool for recoding the new module.
6. **Long-Term Fix for Electrical Problems** If the original module has failed due to age, moisture, or wiring issues, replacing it can provide a lasting solution. Newer modules (even used/refurbished ones) are less likely to fail prematurely compared to original units that have degraded over time.
7. **Warranty or Guarantee Options** Some aftermarket sellers offer warranties on parts, and if purchased from an authorized dealer, the module may come with a limited warranty. This can provide peace of mind if the issue persists.

#### **Cons:**1. **Potential Counterfeit or Low-Quality Parts** The aftermarket for Mercedes parts is flooded with counterfeit or poorly made replicas. A cheap or non-OEM module may fail quickly, cause further electrical issues, or even damage the vehicle s wiring. Always verify the seller s reputation and part authenticity (e.g., check for proper Mercedes part numbers, packaging, and seller reviews).
2. **Electrical Coding and Programming Required** Mercedes-Benz modules often require coding or programming after replacement to ensure proper integration with the vehicle s systems. This may require a visit to a Mercedes dealership or a specialist with the correct diagnostic tools (e.g., Star Diagnostic, DAS, or third-party tools like VCDS). Failure to code the module properly can result in the seat not working at all.
3. **Labor Costs if Not DIY** If you re not comfortable with electrical work or don t have the time to install the module yourself, labor costs at a Mercedes dealership or specialist can be high (often $150 $300 per hour). Some shops may also charge for programming.
4. **Recurring Issues with Seat Systems** The GL350/GL450 s seat systems are notorious for electrical failures. Even after replacing the module, other components (e.g., seat motors, wiring harnesses, or switches) may still fail, leading to repeated repairs. This is a common issue with older Mercedes models due to aging wiring and poor sealing against moisture.
5. **Limited Lifespan of Aftermarket Modules** While a new or refurbished module is an improvement over a failed original, aftermarket parts may not last as long as OEM components. Over time, you might still encounter issues with the seat motors, wiring, or control switches.
6. **Compatibility with Modified Vehicles** If the vehicle has aftermarket seat covers, custom wiring, or modifications, the new module may not work as intended. Some modifications can interfere with the seat s electrical signals, requiring additional troubleshooting.
7. **Risk of Voiding Warranty (If Applicable)** If the vehicle is still under manufacturer warranty, installing an aftermarket part (even if it s a direct replacement) may void coverage for seat-related issues. Always check warranty terms before proceeding.
8. **Complex Installation for Beginners** The seat module is connected to multiple wiring harnesses and may require disconnecting the rear seat cushions. Without proper guidance, there s a risk of damaging wires or connectors during installation.

### **Conclusion:**Replacing the **Mercedes-Benz 1669004304 right seat module** in a 2013 2016 GL350/GL450 is a practical solution for resolving power seat, heating, or control switch failures. The pros such as cost savings, aftermarket availability, and potential long-term reliability outweigh the cons if you source the part carefully, ensure proper coding, and are prepared for possible recurring electrical issues.
However, the cons particularly the risk of counterfeit parts, coding requirements, and the vehicle s history of seat system failures mean this repair is not without challenges. If the issue is purely electrical (e.g., a dead module) and not related to physical damage (e.g., torn wiring, burnt motors), the replacement is justified. But if the problem persists after installation, further diagnostics may be needed.
### **Recommendation:**1. **Verify the Part s Authenticity** Purchase from a reputable seller (e.g., an authorized Mercedes parts dealer, RockAuto, or a trusted online retailer with good reviews). Avoid parts that are significantly cheaper than OEM pricing, as they may be counterfeit.
2. **Check for Coding Requirements** Before buying, confirm whether the module needs to be coded or programmed. If so, research local Mercedes specialists or dealerships that offer this service.
3. **Consider Professional Installation** If you re not experienced with electrical work, hire a Mercedes specialist to install the module and handle coding. This ensures the job is done correctly and reduces the risk of further issues.
4. **Inspect Other Seat Components** While replacing the module, check the seat motors, wiring harnesses, and switches for wear or damage. Addressing these upfront can prevent future failures.
5. **Document the Issue** If the vehicle is under warranty, document the problem thoroughly before proceeding with an aftermarket repair to avoid warranty disputes.
6. **Budget for Potential Follow-Up Repairs** Be prepared for the possibility of additional seat-related issues, especially if the wiring or motors are degraded. Consider a budget of $200 $500 for parts and labor beyond the module replacement.
**Final Verdict:** If the seat module is the confirmed source of the problem and you take precautions to ensure a quality replacement and proper installation, this repair is a worthwhile investment. However, if the vehicle has a history of electrical gremlins, be prepared for ongoing maintenance. For those comfortable with DIY work, the cost savings can be significant; for others, professional help is advisable.
