Review STANDARD MOTOR PRODUCTS A/c Control Relay Chevy fits CAPRICE 1966–1968

The **Standard Motor 68YXWJHV A/C Control Relay** is a precision-engineered electrical component designed specifically for the classic **1966 1968 Chevrolet Caprice**, ensuring seamless operation of the air conditioning system in these iconic muscle cars and full-size sedans. This relay serves as the critical interface between the vehicle s electrical system and the A/C compressor clutch, enabling smooth engagement and disengagement of the compressor while managing power distribution to prevent overloads or short circuits. Crafted with high-quality materials, the relay features a robust **SPDT (Single Pole Double Throw)** switching mechanism, allowing it to handle the substantial current demands of the A/C clutch coil with reliability, even under prolonged use. Its compact yet durable design ensures a secure fit within the Caprice s wiring harness, minimizing the risk of vibration-induced failure a common concern in high-performance or heavily driven vehicles. The relay s internal contacts are precision-plated with **silver or silver alloy**, providing low resistance and extended lifespan, while the insulating housing is engineered to withstand the Caprice s under-hood environment, where temperatures and humidity can fluctuate dramatically. Whether restoring a vintage Caprice to its original glory or upgrading an existing system for modern reliability, this relay delivers the precision switching required to activate the A/C compressor clutch without the risk of arcing or premature wear. Ideal for both DIY enthusiasts and professional mechanics, the **68YXWJHV** relay is a straightforward yet essential component for maintaining the Caprice s legendary comfort and performance, bridging the gap between the driver s climate control demands and the mechanical workings of the air conditioning system.

**Pros and Cons of Buying a Standard Motor 68YXWJHV A/C Control Relay for a 1966-1968 Chevy Caprice**

### **Pros**

1. **Compatibility and Fitment** The relay is specifically designed for the 1966-1968 Chevy Caprice, ensuring proper electrical connections and mechanical operation. This reduces the risk of installation issues or damage to the vehicle s wiring.

2. **Reliability** Standard Motor Company is a well-known manufacturer of automotive relays and switches, known for producing durable, high-quality components. A genuine or high-quality aftermarket relay should provide consistent performance without frequent failures.

3. **Easy Installation** Relays are relatively simple to replace, requiring minimal tools and basic mechanical skill. The wiring diagram for your Caprice should be readily available, making the process straightforward for most DIYers.

4. **Cost-Effective Fix** If the relay is faulty, replacing it is often cheaper than diagnosing other potential causes (such as a failing compressor clutch, blown fuses, or wiring issues). A new relay can restore proper A/C function without extensive repairs.

5. **Prevents Further Damage** A bad relay can cause intermittent or complete failure of the A/C system, potentially leading to compressor clutch burnout or other electrical issues. Replacing it early can prevent more costly repairs down the line.

6. **Widely Available** As a common part for classic Chevy vehicles, this relay can be sourced from multiple suppliers, including eBay, automotive parts stores, and specialty classic car dealers. This ensures availability and competitive pricing.

7. **Standardized Performance** Unlike aftermarket parts that may vary in quality, a Standard Motor relay adheres to industry standards, ensuring consistent operation and compatibility with the vehicle s electrical system.

### **Cons**

1. **Potential Counterfeit or Low-Quality Parts** If purchasing from an unverified seller (especially online), there is a risk of receiving a counterfeit or inferior relay. This could lead to premature failure or poor performance. Always buy from reputable sources.

2. **Limited Availability of Original Equipment (OEM) Parts** While the relay itself is common, finding an exact OEM replacement may be difficult, especially for older vehicles. Aftermarket relays are typically used, which may not always match the original specifications perfectly.

3. **Diagnostic Time Required** Before replacing the relay, you must confirm that it is indeed the source of the problem. Symptoms like a clicking relay, no A/C compressor engagement, or intermittent cooling could stem from other issues (e.g., fuse, wiring, compressor clutch, or low refrigerant). Testing the relay with a multimeter or swapping it with a known-good relay is necessary.

4. **Cost of Additional Tools or Testing Equipment** If you lack basic automotive diagnostic tools (like a multimeter or relay tester), you may need to purchase or borrow them to verify the relay s condition before replacement. This adds to the overall cost.

5. **Risk of Incorrect Installation** Improper wiring or installation (e.g., reversed polarity, loose connections) can damage the relay, the vehicle s electrical system, or even cause a fire. Following the wiring diagram carefully is essential.

6. **Wear and Tear on Other Components** If the A/C system has been running intermittently due to a bad relay, other components (such as the compressor clutch or wiring) may have been stressed. Replacing the relay alone may not fully resolve underlying issues.

7. **Limited Longevity Guarantee** While relays are durable, they are not designed for indefinite use. If the vehicle is driven frequently or in extreme conditions, the relay may eventually fail again, requiring another replacement.

### **Conclusion**

Buying a **Standard Motor 68YXWJHV A/C Control Relay** for your 1966-1968 Chevy Caprice is a practical and cost-effective solution if the relay is confirmed as the source of your A/C issues. The part is well-suited for your vehicle, reliable, and easy to install, making it a strong candidate for DIYers. However, the process requires careful diagnosis to avoid wasting time or money on unnecessary replacements. Additionally, sourcing the relay from a trusted supplier is crucial to ensure quality and authenticity.

If you are confident in your ability to diagnose the problem and perform the replacement, this relay is a solid choice. If you are unsure about the diagnosis or lack the necessary tools, consulting a mechanic or classic car specialist may be worthwhile to avoid further complications.

### **Recommendation**

1. **Verify the Relay is Faulty** Use a multimeter to test the relay s continuity and operation. Swap it with a known-good relay (if available) to confirm the issue.

2. **Purchase from a Reputable Source** Buy the relay from a trusted supplier, such as RockAuto, eBay (with positive seller ratings), or a local classic car parts shop. Avoid suspiciously cheap deals that may indicate counterfeit goods.

3. **Follow Wiring Diagrams Carefully** Refer to your Caprice s wiring diagram (available in repair manuals or online) to ensure correct installation and wiring polarity.

4. **Consider Professional Help if Needed** If you are uncomfortable diagnosing or working on the electrical system, a mechanic familiar with classic Chevys can provide guidance or perform the replacement.

5. **Inspect Other Components** While replacing the relay, check the A/C compressor clutch, fuses, and refrigerant levels to ensure the system operates optimally after the repair.

In summary, this relay is a **strong recommendation** for restoring A/C functionality in your Caprice, provided you take the necessary steps to confirm its condition and install it correctly. The benefits of reliability and ease of replacement outweigh the minor risks when approached methodically.
