Review FORD Oem Factory Sunroof Motor Tested Sm3 fits FOCUS 2006

The **Ford 4S4Z-15790-AA (SM3) Sunroof Motor Assembly** from the **2006 Ford Focus** is a precision-engineered component designed to deliver seamless, reliable operation for the vehicle s panoramic or fixed sunroof system.

The assembly includes a **high-quality plastic housing** that is engineered to match the original vehicle s aesthetic and structural requirements, preventing misalignment or rattles during operation. Compatible with both **manual and automatic sunroof controls**, this motor is equipped with a **reliable electrical interface**, including a **multi-pin connector** that ensures secure and interference-free communication with the vehicle s control module. Whether installed in a **fixed sunroof** for ventilation or a **panoramic sunroof** for expansive views, this motor guarantees consistent performance, reducing the risk of common issues like motor failure, excessive noise, or erratic operation. Ideal for restoration projects, replacements, or upgrades, the **4S4Z-15790-AA** is a direct-fit solution that restores factory-like functionality, making it a trusted choice for mechanics and DIY enthusiasts alike.

### **Pros and Cons of buying a Ford 4S4Z-15790-AA (2006 Focus Sunroof Motor, SM3)**

#### **Pros:**

1. **Common and Widely Available Part** The 4S4Z-15790-AA is a standard sunroof motor for the 2006 Ford Focus, meaning it is easy to find in stock at auto parts stores, online marketplaces, or directly from Ford dealers. This reduces the risk of long wait times or compatibility issues.

2. **Direct Replacement Fit** As a genuine or high-quality aftermarket part, it is designed to fit seamlessly into the 2006 Focus s sunroof mechanism without requiring extensive modifications. This ensures proper functionality and alignment.

3. **Reliability (If New or Genuine)** If purchasing a new or OEM (Original Equipment Manufacturer) version, this motor is built to last, reducing the likelihood of premature failure. Aftermarket options from reputable brands (e.g., Dorman, ACDelco, or Bosch) also offer good durability.

4. **Easy Installation** The sunroof motor is relatively straightforward to replace, especially for those with basic mechanical skills. Most DIYers can complete the job in a few hours with the right tools and instructions.

5. **Prevents Further Damage** A failing sunroof motor can cause water leaks, electrical issues, or damage to the sunroof frame if ignored. Replacing it proactively avoids costly secondary repairs.

6. **Cost-Effective Compared to Full Sunroof Replacement** Replacing just the motor is significantly cheaper than overhauling the entire sunroof assembly, making it a practical solution for minor failures.

---

#### **Cons:**

1. **Age of the Vehicle (2006 Focus)** The 2006 Ford Focus is an older model, meaning the sunroof mechanism may already be worn out or prone to leaks. Replacing just the motor may not solve underlying issues like a damaged seal or frame corrosion.

2. **Potential Compatibility Issues** While the part number suggests compatibility, slight variations in sunroof designs (e.g., manual vs. power adjustments, different trim levels) could require additional modifications or a different part.

3. **Quality Variability in Aftermarket Parts** Cheap or low-quality aftermarket motors may fail prematurely or lack smooth operation. Always verify the brand s reputation and read reviews before purchasing.

4. **Labor Costs if Professional Installation is Needed** If the buyer lacks mechanical experience, hiring a mechanic to install the motor will add to the total cost. Labor fees can range from $100 $200 depending on the shop.

5. **Risk of Recycled or Used Parts** Buying a used or refurbished motor from an unknown seller could lead to hidden defects or reduced lifespan. Genuine or new aftermarket parts are safer but more expensive.

6. **Additional Wear on Related Components** If the sunroof tracks, seals, or cables are degraded, replacing just the motor may not fully restore functionality. A thorough inspection of the entire sunroof system is advisable.

7. **Potential for Electrical Issues** Older vehicles may have frayed wiring or corroded connectors in the sunroof circuit. If these issues aren t addressed, the new motor may not work properly.

---

### **Conclusion:**

The **Ford 4S4Z-15790-AA sunroof motor (SM3) for a 2006 Focus** is a practical and accessible replacement for a failing sunroof mechanism. Its widespread availability, ease of installation, and cost-effectiveness make it a viable option for restoring basic sunroof functionality. However, the decision should consider the vehicle s age, the condition of surrounding components, and the quality of the part being purchased.

If the sunroof was previously functional and the failure is isolated to the motor, this part is a solid choice. However, if the vehicle has a history of sunroof leaks or mechanical issues, a more comprehensive inspection (or even a full sunroof rebuild) may be necessary to ensure long-term reliability.

---

### **Recommendation:**

1. **Verify the Part s Condition** If buying used, test the motor for smooth operation and check for physical damage. Prefer a new or refurbished part from a trusted supplier (e.g., RockAuto, Amazon, or a local auto parts store with return policies).

2. **Inspect the Sunroof System** Before purchasing, ensure the sunroof tracks, seals, and cables are in good condition. If any of these are worn, replace them simultaneously to avoid future problems.

3. **Consider Professional Installation** If unsure about DIY repairs, have a mechanic install the motor to guarantee proper alignment and electrical connection.

4. **Budget for Potential Additional Costs** Account for labor fees if hiring a professional, as well as any extra parts needed (e.g., new seals, lubricants).

5. **Check for Genuine vs. Aftermarket Options**

- **Genuine Ford part (if available):** More expensive but guaranteed compatibility.

- **High-quality aftermarket (e.g., Dorman, Bosch):** Reliable and often cheaper than OEM.

6. **Test the Motor After Installation** Once installed, operate the sunroof multiple times to ensure smooth movement and no unusual noises or leaks.

**Final Verdict:** The **4S4Z-15790-AA is a good choice for a straightforward sunroof motor replacement**, provided the rest of the system is in decent condition. For older vehicles, prioritize quality and thoroughness to avoid recurring issues. If the sunroof has been problematic before, weigh the cost of a full rebuild against the convenience of a motor-only swap.
