### **Pros and Cons of Buying a Standard Motor 13ZWGY A/C Selector Switch for a 1979 Chevy C10**

#### **Pros:**

1. **Authentic Fit and Functionality** This is an original or high-quality reproduction part designed specifically for the 1979 Chevy C10, ensuring proper fitment and compatibility with the vehicle s air conditioning system. It will integrate seamlessly with the existing wiring and controls.

2. **Reliability and Durability** Standard Motor is a well-known manufacturer of automotive switches, known for producing parts that are built to last. A high-quality switch reduces the risk of frequent failures or malfunctions, which can be common with aftermarket knockoffs.

3. **Easy Installation** Since it is a direct replacement, installation typically requires minimal effort. Most users can replace the switch themselves with basic tools, though some may need to disconnect the wiring harness carefully to avoid damage.

4. **Compatibility with Aftermarket Upgrades** If you ve modified your C10 s air conditioning system (e.g., upgraded compressor, added remote controls, or installed a digital gauge cluster), this switch will work with those changes without compatibility issues.

5. **Avoids Common Issues with Cheap Alternatives** Cheap or generic switches may fail prematurely, cause intermittent A/C operation, or even short-circuit. A reputable part like this one minimizes those risks.

6. **Preserves Original Aesthetics** If you re maintaining the truck s original appearance, this switch will match the factory design, whereas aftermarket switches may look out of place.

7. **Warranty Coverage** Standard Motor parts often come with a warranty, providing peace of mind in case of defects. This is especially useful if you re not experienced with electrical repairs.

#### **Cons:**

1. **Cost** A genuine or high-quality reproduction switch will be more expensive than a cheap eBay or Amazon alternative. For a 1979 Chevy C10, prices may range from $30 to $80 depending on condition and seller. If you re on a tight budget, this could be a drawback.

2. **Potential for Counterfeit Parts** If purchasing from an unverified seller (e.g., a random online marketplace), there s a risk of receiving a counterfeit or low-quality switch. Always buy from reputable dealers or sellers with good reviews.

3. **Limited Customization** Unlike modern aftermarket switches, this part does not offer additional features (e.g., LED backlighting, digital displays, or programmable settings). If you want a more advanced control system, you ll need to pair it with other modifications.

4. **Availability Issues** While not extremely rare, finding a genuine or high-quality switch may require searching multiple sources. Some sellers may not stock this specific part, leading to delays.

5. **Possible Wiring Complications** If the original switch was damaged due to corrosion or poor connections, replacing it may require cleaning or repairing the surrounding wiring harness. This could add unexpected time or cost to the project.

6. **No Guarantee of Long-Term Performance** Even high-quality switches can fail over time due to wear, electrical surges, or environmental factors (e.g., moisture in the cabin). Regular maintenance (e.g., cleaning contacts) may be necessary.

7. **Not Ideal for Heavy Modifications** If you ve heavily modified your C10 s electrical system (e.g., added a new fuse box, rewired the entire cab, or installed a custom A/C control panel), this switch may not integrate as smoothly as a fully customized solution.

### **Conclusion**

Buying the **Standard Motor 13ZWGY A/C selector switch for a 1979 Chevy C10** is a practical choice for most owners who prioritize **reliability, authenticity, and ease of installation**. The part is well-suited for those who want a direct replacement without sacrificing performance or fit. However, if budget is a major concern or if you re open to aftermarket alternatives, cheaper switches *might* work but they come with higher risks of failure and compatibility issues.

For the average C10 owner, the **pros outweigh the cons**, especially if you value **longevity, ease of use, and compatibility with stock or lightly modified systems**. The switch is a straightforward upgrade that can resolve A/C control problems without requiring extensive modifications.

---

### **Recommendation**

- **Buy from a reputable seller** (eBay, RockAuto, or a local auto parts store with a good return policy) to avoid counterfeit or damaged parts.

- **Inspect the switch upon arrival** Check for signs of wear, corrosion, or manufacturing defects before installation.

- **Consider pairing with a wiring harness inspection** If the original wiring is corroded or damaged, clean or replace it to ensure long-term reliability.

- **If on a tight budget**, weigh the cost against the risk of failure. A cheap switch might save money upfront but could lead to repeated replacements or A/C malfunctions.

- **For heavy modifications**, research whether a custom switch or control panel would be more beneficial in the long run.

**Final Verdict:** **Purchase the Standard Motor switch** if you want a **reliable, authentic, and hassle-free solution** for your 1979 Chevy C10 s A/C controls. It s the safest and most practical choice for most owners.
