### **Pros and Cons of buying a 135-10009R Passenger Right Rear Window Regulator (2017 2020 Cadillac CTS/V) from a Third-Party Seller**

1. **Direct Fitment** The part is designed specifically for the 2017 2020 Cadillac CTS/V (and possibly other GM vehicles like the CTS, ATS, and some Chevrolet models) with the correct window regulator assembly number (135-10009R). This reduces the risk of compatibility issues compared to aftermarket or generic replacements.

2. **OEM Quality** As an original equipment manufacturer (OEM) part, it should meet the same durability and performance standards as the factory unit. This can translate to smoother operation, better sealing, and fewer premature failures compared to lower-quality aftermarket alternatives.

3. **Warranty Coverage** If purchased from a reputable seller (e.g., an authorized dealer, GM parts distributor, or a trusted online retailer with return policies), the part may come with a warranty (e.g., 12 24 months). This provides recourse if the regulator fails shortly after installation.

4. **Easier Installation** Since it s a direct replacement, the part should fit without extensive modifications. The wiring harness, motor, and mechanical components align with the factory design, simplifying the repair process for most DIYers or mechanics.

5. **Reliability for Long-Term Use** OEM parts are engineered for the vehicle s lifespan, reducing the likelihood of repeated failures that can occur with cheaper, non-genuine components. This is particularly important for the rear passenger window, which is less frequently used but still critical for comfort and safety.

6. **Access to Technical Support** If issues arise during installation or use, OEM parts suppliers often provide technical documentation or customer service to assist with troubleshooting.

---

1. **Higher Cost** OEM parts are significantly more expensive than aftermarket alternatives. The price for a 135-10009R regulator can range from **$150 $300 **, depending on the seller and whether it s new or refurbished. This can be a substantial investment if the window regulator is the only issue with the vehicle.

2. **Limited Availability** OEM parts may not always be in stock at local dealers or online marketplaces. Purchasing from a third-party seller (e.g., eBay, RockAuto, or a used parts lot) introduces risks such as counterfeit parts, damaged units, or incorrect listings. Verifying the seller s reputation and part authenticity is crucial.

3. **Potential for Counterfeit Parts** The aftermarket for OEM parts is rife with counterfeit or refurbished units that may not function as intended. These parts might fail prematurely or lack proper seals, leading to further issues like water leaks or motor burnout.

4. **Shipping Risks** If ordering online, the part may be damaged during transit, especially if not properly packaged. Some sellers offer free returns, but this adds inconvenience and potential delays.

5. **Installation Complexity** While the part is a direct fit, the installation process can be labor-intensive, particularly if the window track is corroded, the glass is stuck, or the surrounding trim panels are difficult to remove. This may require additional tools or expertise, increasing the total cost if professional labor is needed.

6. **No Guarantee of Original Condition** Even if labeled as "new," some OEM parts sold by third parties may be refurbished or returned units that have been reused. These could have hidden defects (e.g., worn gears, faulty motors) that aren t immediately apparent.

7. **Potential for Additional Issues** If the window regulator failure is due to a larger problem (e.g., a faulty motor controller, wiring issues, or track corrosion), replacing just the regulator may not fully resolve the problem. The underlying cause might recur, requiring further repairs.

### **Conclusion**

Buying the **135-10009R passenger right rear window regulator** as an OEM part is the most reliable choice for ensuring a long-term, trouble-free fix for your 2017 2020 Cadillac CTS/V. The benefits of direct fitment, OEM quality, and warranty coverage outweigh the higher cost for most owners who prioritize durability and ease of installation. However, the risks of counterfeit parts, shipping damage, and installation challenges especially when purchasing from third-party sellers must be carefully considered.

If you re comfortable with research and verification, purchasing from an **authorized GM parts distributor, a trusted online retailer with return policies, or a reputable used parts lot** (where you can inspect the part) is ideal. Alternatively, if budget is a concern, a **high-quality aftermarket regulator** (e.g., from Dorman, Spectra, or a brand with strong reviews) could be a cost-effective alternative, provided it s properly researched for compatibility.

---

### **Recommendation**

- **GM Parts Direct** (official dealer parts)

- **RockAuto** (with verified seller ratings)

- **eBay** (only from top-rated sellers with return policies)

- **Local GM dealership parts departments** (for physical inspection)

2. **Check for Authenticity** Request a **bill of materials (BOM) number** or **GM part number verification** to ensure it s not a counterfeit. Some sellers provide serial number checks.

3. **Inspect the Part Before Purchase** If possible, ask for photos or a video of the part in good condition. Look for signs of wear, corrosion, or damage to the motor, gears, or seals.

4. **Consider Installation Support** If you re not experienced with window regulator replacements, factor in the cost of professional labor (typically **$100 $200 per hour**). Some sellers offer installation guides or video tutorials.

5. **Compare with Aftermarket Options** If the OEM price is prohibitive, research aftermarket alternatives (e.g., **Dorman 950-10009R, Spectra 135-10009R**) and read reviews for reliability. Ensure the part is listed as a direct replacement for your vehicle year.

6. **Address Underlying Issues** If the window was stuck due to track corrosion or a faulty motor controller, consider cleaning the tracks or replacing the motor controller alongside the regulator to prevent future problems.

For **long-term reliability and peace of mind**, the **OEM 135-10009R regulator is the best choice**, provided it s sourced from a trusted seller. If cost is a major concern, a **high-quality aftermarket part with strong reviews** can be a viable alternative, but always prioritize compatibility and authenticity. Avoid cheap, unbranded parts that may fail quickly and exacerbate the issue.
