Review PONTIAC Sunroof Motor fits PRIX GRAND 2007
The **Pontiac 7103-GP-2000B-B (2007 Prix Sunroof Motor)** and its complementary **7104-GP-2000B-B** component represent a high-quality, factory-specification electric sunroof motor assembly designed exclusively for the 2007 Pontiac G6, specifically the **GXP and Sunfire** models equipped with the **Sunroof option**. This meticulously engineered system is engineered to deliver smooth, reliable operation while maintaining the vehicle s sleek, premium aesthetic. The **7103-GP-2000B-B** serves as the primary sunroof motor, featuring a robust, corrosion-resistant construction with a durable brushed aluminum housing that ensures longevity even in harsh driving conditions. Inside, a precision-wound electric motor drives a high-torque gear mechanism, allowing for effortless opening, closing, and locking of the sunroof panel with minimal effort. The motor operates at an optimal voltage of **12V**, drawing power directly from the vehicle s electrical system while incorporating a built-in **limit switch** to prevent over-travel and ensure safe, controlled movement.
Complementing the motor is the **7104-GP-2000B-B**, which functions as the **sunroof control switch module**, a critical component that interfaces directly with the vehicle s powertrain control module (PCM). This switch module is designed to be mounted in the center console, providing the driver with intuitive control over the sunroof s operation via a dedicated push-button interface. The switch includes **momentary and hold functions**, allowing for quick adjustments or full opening/closing with a single press. Its wiring harness is pre-assembled and color-coded for easy installation, featuring **high-grade, weatherproof connectors** that resist corrosion and ensure a secure electrical connection. Together, these components form a seamless, factory-matched system that replicates the performance of the original equipment, offering drivers the convenience of a fully functional sunroof without compromising on quality or reliability.
For installation, the **7103-GP-2000B-B** motor is designed to replace the factory unit with minimal modifications, requiring only basic tools and a clear understanding of the vehicle s wiring diagram. The motor mounts securely to the sunroof frame using the original brackets, ensuring proper alignment and tension for smooth operation. The **7104-GP-2000B-B** switch module integrates seamlessly with the existing console wiring, often requiring only a splice or direct connection to the sunroof control circuit. Both components are built to withstand the rigors of daily driving, featuring **high-temperature-resistant insulation** and **vibration-dampening mounts** to prevent premature wear. Whether restoring a classic Pontiac or upgrading an existing system, this sunroof motor and switch combination delivers the performance and durability expected from Pontiac s original equipment, ensuring a hassle-free, premium driving experience.
### **Analysis of buying a Pontiac G6 (2007) with Sunroof and 7104-GP-2000B-B Motor**
#### **Overview**
The **Pontiac G6 (2007)** with a **sunroof** and the **GM 7104-GP-2000B-B 2.0L turbocharged engine** (also known as the **LNF engine**) is a mid-size sedan that offers a balance of performance, comfort, and practicality. However, like any vehicle, it has strengths and weaknesses that should be carefully considered before purchasing.
---
### **Pros**
1. **Turbocharged Engine Performance**
- The **2.0L turbocharged engine (7104-GP-2000B-B)** provides **168 175 horsepower and 160 lb-ft of torque**, making it more powerful than naturally aspirated alternatives of its time.
- Turbocharging allows for **better fuel efficiency than larger V6 engines** while maintaining decent acceleration.
- The engine is **front-wheel drive**, which is more fuel-efficient than AWD or RWD setups in city driving.
2. **Sunroof for Comfort and Luxury Feel**
- A **sunroof adds to the cabin s ambiance**, making long drives more enjoyable, especially in good weather.
- It provides **natural light and ventilation**, reducing reliance on AC in mild conditions.
3. **Decent Fuel Economy (For Its Class)**
- The **2.0T engine** typically achieves **around 20 22 MPG in the city and 28 30 MPG on the highway**, which was competitive for its time.
- Better than many V6-powered sedans of the era, though not as efficient as modern turbocharged or hybrid vehicles.
4. **Comfortable Interior & Ride Quality**
- The **G6 has a smooth ride**, with well-padded seats and a **quiet cabin**, making it suitable for daily commuting.
- The **sunroof enhances the premium feel**, though materials may not be as high-end as luxury brands.
5. **Affordability & Availability of Parts**
- Pontiacs (and GM vehicles in general) have **widely available parts**, making repairs and maintenance relatively straightforward.
- The **2.0L turbo engine is common enough** that finding mechanics familiar with it is easier than with rare or discontinued engines.
6. **Manual Transmission Option (If Available)**
- Some **2007 G6 models came with a 6-speed manual transmission**, which can be **more engaging to drive** and improve fuel economy compared to automatics.
7. **Safety Features (For Its Era)**
- The **2007 G6 includes standard stability control, anti-lock brakes (ABS), and side airbags**, which were common safety features at the time.
- **Front crash prevention (if equipped)** was an optional but useful safety upgrade.
8. **Modding & Tuning Potential**
- The **2.0L turbo engine is tuner-friendly**, with aftermarket support for **boost upgrades, turbo swaps, and performance chips**.
- Many enthusiasts have pushed this engine to **300 HP** with proper modifications.

### **Cons**
1. **Reliability Concerns with the 2.0L Turbo Engine (LNF)**
- The **GM 7104-GP-2000B-B (LNF) engine** has a **reputation for oil consumption and turbocharger failures** if not properly maintained.
- **Common issues include:**- **Oil leaks** (valve cover, oil pan, rear main seal).
- **Turbocharger failure** (often due to **low oil pressure or poor maintenance**).
- **Rod bearing wear** (some engines develop **knocking or metal shavings** in oil).
- **Solution:** Ensure the car has **full service records**, especially **oil changes every 5,000 miles** (or as recommended by GM for turbo engines).
2. **Transmission Issues (Automatic Models)**
- The **6-speed automatic transmission (6T70)** in some G6s has had **reports of rough shifting, delayed engagement, and solenoid failures**.
- **Manual transmissions** are generally more reliable but less common.
3. **Electrical & Infotainment Problems**
- The **2007 G6 s infotainment system (if equipped with a CD/MP3 player) can be finicky**, with **button failures and screen issues**.
- **Power accessories (windows, locks) may develop intermittent problems** over time.
4. **Resale Value & Market Demand**
- Pontiacs **lost popularity after 2010**, and the G6 is no longer in production, meaning **resale value is low**.
- Finding **parts and mechanics** may become harder in the long term compared to more common brands.
5. **Sunroof Maintenance Risks**
- **Sunroofs can leak** if the seals degrade, leading to **water damage to the headliner and roof structure**.
- **Mechanical failures** (e.g., motor or cable issues) can make the sunroof inoperable.
6. **Fuel & Emissions Compliance**
- The **2007 model year was before stricter emissions regulations**, but the **2.0T engine may require an EGR cooler or catalytic converter check** if it has been modified.
- **Ethanol-blended fuel (E10) is fine**, but **premium fuel is not required** unless the car has been tuned for it.
7. **Safety Recalls & Structural Issues**
- Some **2007 G6s had recalls for airbag or seatbelt issues** always check **NHTSA or GM recall databases** before buying.
- **Rust** can be an issue in snowy or humid climates, especially if the car has been poorly maintained.
8. **Limited Modern Tech & Connectivity**
- The **G6 lacks Bluetooth, USB, or modern infotainment systems**, making it less convenient for today s drivers.
- **No Apple CarPlay or Android Auto** only basic radio and CD/MP3 functionality.
