Review GM Genuine Passenger Side Door Lock Harness Contact fits 2015–2018

The **GM 19316404 Passenger Door Lock Harness Contact** is a precision-engineered electrical component designed to ensure seamless functionality within a vehicle s door lock system. This high-quality contact is specifically tailored for General Motors applications, serving as a critical link between the door lock actuator and the vehicle s electrical wiring harness. Crafted from durable, corrosion-resistant materials, this contact is built to withstand the rigors of daily use, including exposure to varying temperatures, moisture, and mechanical stress, which are common in automotive environments. Its robust construction minimizes the risk of oxidation or degradation over time, thereby maintaining reliable electrical conductivity and preventing intermittent lock failures or power interruptions.

The design of the GM 19316404 Passenger Door Lock Harness Contact incorporates a secure, interference-fit connection that ensures a tight and stable bond with the surrounding wiring and harness components. This precision engineering reduces the likelihood of loose connections, which can lead to erratic door lock behavior, such as jamming or failure to engage properly. The contact is engineered to align perfectly with the vehicle s electrical system, providing optimal signal transmission between the door lock switch and the actuator motor, whether the door is being locked, unlocked, or powered down. Its compact yet sturdy form factor allows for easy installation, even in tight or confined spaces within the door panel, without compromising functionality or aesthetics.

Beyond its mechanical and electrical reliability, this component adheres to strict automotive industry standards for safety and performance. It is designed to meet or exceed OEM specifications, ensuring compatibility with a wide range of GM vehicles equipped with passenger door lock systems. Whether used in replacement scenarios or as part of a comprehensive door lock repair, the GM 19316404 Passenger Door Lock Harness Contact delivers consistent performance, reducing the risk of electrical malfunctions that could compromise the vehicle s security or user experience. For technicians and DIY enthusiasts alike, this component represents a dependable solution for restoring or maintaining the integrity of a vehicle s door lock mechanism, ensuring smooth operation and long-term durability.

### **Pros and Cons of buying a GM 19316404 Passenger Door Lock Harness Contact**

#### **Pros:**

1. **Direct Fitment** This part is designed specifically for General Motors vehicles, ensuring compatibility without modifications. It is likely a direct replacement for the original equipment manufacturer (OEM) harness contact, reducing the risk of installation issues.

2. **Reliability** As an OEM or high-quality aftermarket part, it should function reliably, reducing the likelihood of electrical failures or intermittent door lock malfunctions.

3. **Cost-Effective** Compared to labor-intensive repairs (such as rewiring or replacing an entire door module), purchasing and installing this single component is a straightforward and budget-friendly solution.

4. **Prevents Further Damage** If the original harness contact failed due to wear, corrosion, or electrical issues, replacing it can prevent secondary damage to the door lock mechanism or wiring harness.

5. **Ease of Installation** Since it is a single component, installation is typically simpler than replacing an entire assembly. Most mechanics or DIYers with basic electrical knowledge can handle the job.

6. **Warranty Coverage** If purchased from a reputable dealer or online retailer, the part may come with a warranty, offering protection against defects.

#### **Cons:**

1. **Potential Counterfeit Parts** If bought from an untrusted seller, there is a risk of receiving a low-quality or counterfeit part that fails prematurely or does not fit correctly.

2. **Limited Availability** Depending on the vehicle model and year, this part may be discontinued or difficult to source, requiring extra effort to find the correct replacement.

3. **Diagnostic Uncertainty** If the issue is not solely due to the harness contact (e.g., a faulty door lock motor, wiring damage, or a faulty door control module), replacing just this part may not resolve the problem, leading to wasted time and money.

4. **Skill Dependency** While the part itself is simple, improper installation (e.g., incorrect wiring or improper crimping) could cause electrical shorts or further damage.

5. **Cost Variability** Prices can vary significantly depending on the seller, with some offering inflated prices for the same part.

6. **Vehicle-Specific Limitations** If the vehicle has extensive wiring damage or other underlying issues (e.g., a failing door control module), replacing just the harness contact may provide temporary relief but not a permanent fix.

### **Conclusion:**

The **GM 19316404 Passenger Door Lock Harness Contact** is a practical and cost-effective solution for addressing a faulty harness contact in a GM vehicle s door lock system. It offers a straightforward replacement option that can restore functionality if the issue is isolated to this component. However, its effectiveness depends on accurate diagnosis, proper installation, and sourcing from a reliable supplier.

If the door lock problem persists after replacement, further diagnostics (such as testing the door control module, wiring, or lock motor) may be necessary to identify the root cause.

---

### **Recommendation:**

1. **Verify the Diagnosis** Before purchasing, confirm that the harness contact is indeed the faulty component. Use a multimeter to test for continuity or resistance, or consult a professional mechanic if unsure.

2. **Purchase from a Trusted Source** Buy the part from an authorized GM dealer, reputable online retailer (e.g., RockAuto, AutoZone, or Amazon with verified sellers), or a parts specialist to avoid counterfeit or damaged stock.

3. **Follow Installation Guidelines** Carefully follow the vehicle s wiring diagram and any provided installation instructions. If unsure, seek assistance from a mechanic to ensure proper connection and avoid electrical issues.

4. **Consider a Full System Check** If the problem recurs after replacement, have a professional inspect the door lock system, including the control module, wiring, and motor, to rule out other failures.

5. **Keep a Backup** If the vehicle is frequently used, consider keeping a spare harness contact on hand for future reference.

By taking these steps, you can maximize the likelihood of a successful repair while minimizing the risk of further complications.
