Review GM General Motors Rear Compartment /trunk Lid Power Lock Solenoid Oem #522 fits 1971–1978

This **GM 522-style rear/trunk lid power lock solenoid** (part number **9808558**, compatible with **1971 1978 General Motors vehicles**) represents a critical yet often overlooked component in the vintage automotive electrical system, bridging the gap between mechanical reliability and modern convenience. Designed to operate within the robust yet precise framework of early GM body control modules, this solenoid is engineered to engage the trunk lid s locking mechanism with a smooth, silent, and fail-safe operation essential for maintaining both security and functionality in classic vehicles like the **Chevrolet Impala, Caprice, Nova, or Buick Skylark**. Crafted from high-quality materials, including a durable metal housing and corrosion-resistant internal wiring, it is built to withstand the rigors of frequent use while resisting the degradation caused by exposure to moisture, dust, and temperature fluctuations common in older vehicles. The solenoid s internal coil is precision-wound to deliver consistent magnetic force, ensuring reliable activation of the locking mechanism regardless of battery voltage fluctuations a critical feature for vehicles with aging electrical systems. When integrated into the trunk lid s linkage, it seamlessly replaces manual or spring-loaded mechanisms, offering a quiet, effortless alternative that enhances the driving experience while preserving the vehicle s original aesthetic. Whether restoring a showroom-worthy classic or addressing a functional issue in a daily driver, this solenoid is a testament to GM s engineering legacy, combining simplicity with enduring performance to keep the trunk lid secure and operational for decades to come.

### **Pros and Cons of Buying a GM 522 Rear/Trunk Lid Power Lock Solenoid (Part Numbers: 9808558, 1971, 1978)**

1. **Direct Compatibility** The GM 522 solenoid is a well-documented part designed specifically for General Motors vehicles from the early 1970s, including models from 1971 and 1978. This means it should fit without major modifications, reducing installation hassle.

2. **Reliability** GM s mechanical and electrical components from this era were generally robust, and the 522 solenoid is a standard part used across multiple models. If sourced from a reputable supplier, it should function as intended without frequent failures.

3. **Ease of Installation** Power lock solenoids are relatively straightforward to replace. Most DIYers with basic mechanical and electrical skills can install it themselves, saving labor costs if doing it professionally.

4. **Availability of Replacement Parts** Since this is an older but common GM part, you can often find it at auto salvage yards, online marketplaces (eBay, RockAuto, PartsGeek), or specialty aftermarket suppliers. This increases the likelihood of quick sourcing.

5. **Cost-Effective Fix** Replacing a faulty solenoid is usually cheaper than overhauling the entire power lock system. A new or refurbished solenoid typically costs between $20 and $60, depending on condition and supplier.

6. **Prevents Further Damage** A failing solenoid can cause intermittent lock failures, which may lead to wiring issues or damage to the motor if left unaddressed. Replacing it early prevents more extensive (and costly) repairs.

7. **Standardized Design** The 522 solenoid follows a consistent design across compatible GM vehicles, meaning troubleshooting and replacement are more predictable compared to aftermarket or non-GM parts that may require additional adjustments.

---

1. **Age and Wear** Parts from this era may show signs of wear, corrosion, or degradation, especially if sourced from a salvage yard. A used solenoid might not last as long as a new one, requiring potential re-replacement sooner.

2. **Electrical Compatibility Issues** Older wiring harnesses and power lock systems can develop corrosion or frayed wires over time. If the solenoid itself is fine but the surrounding wiring is damaged, the problem may persist even after replacement.

3. **Limited Supplier Options** While the part is available, not all suppliers offer new or refurbished units. Some may only carry used parts, which could introduce reliability concerns. Researching suppliers thoroughly is essential.

4. **Potential for Counterfeit Parts** Older GM parts, especially those sold online, can sometimes be counterfeit or rebranded knockoffs. These may fail prematurely or not fit correctly, leading to frustration and wasted money.

5. **Diagnostic Challenges** If the solenoid is replaced but the issue persists, diagnosing whether the problem lies with the solenoid, wiring, fuse, relay, or motor can be time-consuming. Additional testing (e.g., multimeter checks) may be required.

6. **Compatibility Variations** While the 522 solenoid is widely compatible, slight variations in mounting or wiring between specific GM models (e.g., Chevy, Buick, Oldsmobile) could require minor adjustments during installation.

7. **Environmental Factors** Exposure to moisture, salt, or extreme temperatures (common in older vehicles) can accelerate wear on the solenoid. If the vehicle s trunk lid mechanism is rusted or seized, replacing just the solenoid may not fully resolve the issue.

Buying a GM 522 rear/trunk lid power lock solenoid (part numbers 9808558, 1971/1978) is a practical and cost-effective solution for restoring power lock functionality in compatible vehicles. The part is widely available, relatively easy to install, and avoids the need for more extensive repairs. However, potential buyers should be mindful of the part s age, wiring condition, and supplier reliability. Opting for a new or refurbished solenoid from a trusted source minimizes risks, while thorough diagnostics ensure the underlying system (wiring, motor, fuses) is also in working order.

---

1. **Source the Part Carefully** Prioritize suppliers that offer new or certified refurbished solenoids (e.g., RockAuto, PartsGeek, or local auto parts stores with return policies). Avoid parts with visible corrosion or damage.

2. **Inspect the Wiring and Harness** Before installation, check the wiring leading to the solenoid for fraying, corrosion, or loose connections. Clean or replace damaged wires to prevent future issues.

3. **Test the Solenoid** If possible, test the new solenoid before final installation by temporarily connecting it to the vehicle s power source (with the trunk lid open) to confirm it engages and disengages the lock mechanism.

4. **Consider a Full System Check** If the solenoid replacement doesn t resolve the issue, investigate the power lock motor, fuses, relays, or ground connections, as these components can also fail over time.

5. **Document the Process** Keep records of the part s origin, installation steps, and any troubleshooting performed. This helps with future diagnostics and warranty claims if needed.

For most DIYers or mechanics, replacing the solenoid is a straightforward fix worth attempting. However, if the vehicle s power lock system is severely degraded, a more comprehensive evaluation may be warranted.
