### Pros and Cons of Buying a GM 12016892 Wiper Motor Wires Harness Extension (1984 1987 Corvette)
#### **Pros:**1. **Compatibility** This part is specifically designed for 1984 1987 Corvette models, ensuring a direct fit without modification. The GM part number guarantees it will integrate seamlessly with the vehicle s wiring and mechanical systems.
2. **Reliability** GM parts, especially those from this era, are generally built to last. The wiper motor harness extension is a critical component for proper wiper operation, and a genuine or high-quality aftermarket replacement reduces the risk of electrical failures or loose connections.
3. **Prevents Common Issues** In older Corvettes, worn or damaged wiper motor wiring can cause intermittent operation, slow wipers, or complete failure. Replacing the harness extension resolves these problems and prevents further deterioration of the system.
4. **Easy Installation** The harness extension is a straightforward repair, typically requiring minimal tools and time. Most owners or even those with basic mechanical knowledge can replace it without professional assistance.
5. **Cost-Effective** Compared to replacing the entire wiper motor or wiring loom, the harness extension is a relatively inexpensive fix. It extends the lifespan of the existing system, saving money in the long run.
6. **Improves Safety** Functional windshield wipers are essential for visibility in rain, snow, or debris. A faulty wiper system compromises safety, so addressing this issue promptly is critical.
7. **Preserves Originality** If you re maintaining the vehicle s originality, using a GM part ensures authenticity. Aftermarket parts may not always match the original fit or quality.

#### **Cons:**1. **Age and Wear** The part itself may be old, especially if sourced from a salvage yard or used market. Over time, rubber insulators or wiring can degrade, leading to potential future issues if the part isn t in pristine condition.
2. **Limited Availability** While GM parts are widely available, finding a specific 1984 1987 Corvette wiper motor harness extension may require ordering from a specialty auto parts supplier. This could involve waiting for shipping or paying extra for expedited delivery.
3. **Potential for Counterfeit Parts** If purchasing from an online marketplace, there s a risk of receiving a knockoff or low-quality replica. Always verify the seller s reputation and part authenticity.
4. **Additional Diagnostics Needed** If the wiper motor itself is failing alongside the harness, replacing just the extension won t solve the underlying problem. You may need to test the motor s functionality before concluding the harness is the sole issue.
5. **Corrosion Risk** Older Corvettes, especially those exposed to salt or moisture, may have corroded terminals or wiring. The new harness extension could fail if the connections to the motor or fuse box aren t properly cleaned and secured.
6. **Skill Dependency** While the installation is simple, improper handling (e.g., stripping wires or misrouting the harness) could cause new problems. Those unfamiliar with electrical work may need to consult a guide or professional.

### **Conclusion:**The GM 12016892 wiper motor harness extension is a practical and cost-effective solution for restoring proper wiper function in a 1984 1987 Corvette. Its compatibility, reliability, and ease of installation make it a strong candidate for DIY repairs. However, potential buyers should ensure they re purchasing a genuine or high-quality part, verify that the wiper motor itself is functional, and address any underlying corrosion or wiring issues to prevent future failures.
If the wiper system has been unreliable for an extended period, it may also be worth inspecting the motor and fuse relay for additional wear. For most owners, replacing the harness extension is a minor but impactful upgrade that enhances both performance and safety.
### **Recommendation:**- **Purchase from a reputable source**, such as a GM parts dealer, RockAuto, or a trusted salvage yard, to ensure authenticity.
- **Inspect the wiper motor and connections** before installation to confirm the issue is isolated to the harness.
- **Follow wiring diagrams** during installation to avoid misrouting or damaging wires.
- **Consider upgrading to a modern aftermarket harness** if the original part is difficult to source, provided it meets OEM specifications.
- **Test the wipers thoroughly** after installation to confirm the repair was successful.
For the average Corvette owner, this is a worthwhile and straightforward repair that extends the life of the vehicle s electrical system.
