### Pros and Cons of Buying a GM P4620222 (1979 1996 Van Exterior Door Handle Latch)
#### **Pros:**1. **Common and Widely Available** This part is produced by General Motors and is used across multiple models from 1979 to 1996, making it easy to find replacements, whether new or refurbished. Its popularity ensures a steady supply from auto parts retailers, online marketplaces, and salvage yards.
2. **Standardized Design** The latch mechanism is a common door handle assembly, meaning it is designed to fit reliably without extensive modifications. This reduces the risk of compatibility issues when installing it on a compatible vehicle.
3. **Durability** GM parts, especially those from the late 1970s to mid-1990s, were built with solid materials like steel and zinc-plated components, which can withstand regular use if the part itself is in good condition.
4. **Affordable Cost** Since this is a mass-produced part, it is generally inexpensive compared to aftermarket or specialty replacements. Prices typically range from $20 to $50, depending on whether it is new, refurbished, or used.
5. **Easy Installation** The latch is designed for straightforward installation, often requiring only basic tools (screwdrivers, pliers, and possibly a rubber mallet for stubborn parts). Many DIYers can replace it without professional assistance.
6. **Compatibility with Aftermarket Parts** If the latch fails, you can often find aftermarket alternatives (e.g., from ACDelco or other brands) that are drop-in replacements, ensuring no need for customization.
7. **Long-Term Reliability** If the latch is functioning correctly, it can last for years without frequent failures, especially if the vehicle is not subjected to extreme conditions (e.g., heavy rust, frequent door slamming, or abuse).

#### **Cons:**1. **Potential Rust and Wear** Parts from this era, especially those from older vehicles, may suffer from rust, corrosion, or worn-out internal mechanisms. If purchasing a used or salvaged latch, inspect it closely for signs of deterioration.
2. **Worn or Stretched Springs** Over time, the internal springs that engage the latch may weaken or stretch, causing the door to rattle or fail to latch properly. This can require additional maintenance or replacement of the springs.
3. **Compatibility Variations** While the P4620222 is a standard part, slight variations in door design (e.g., different trim levels, body styles, or aftermarket modifications) could require minor adjustments during installation.
4. **Limited Warranty on New Parts** If purchasing a new OEM or ACDelco part, warranties may be short (e.g., 12 24 months) or void if the vehicle is not serviced by a dealer. Aftermarket parts may have even shorter or no warranties.
5. **Difficulty Finding Exact Matches for Custom Vans** Some aftermarket or heavily modified vans (e.g., those with custom bodywork or reinforced doors) may not accommodate the standard latch without modifications.
6. **Risk of Counterfeit Parts** When buying online, there is a chance of receiving a counterfeit or low-quality replica, especially from unverified sellers. Always purchase from reputable sources (e.g., RockAuto, AutoZone, or dealer parts departments).
7. **Potential for Hidden Damage** If the latch is being removed from a salvage vehicle, there may be hidden damage (e.g., cracked housing, broken pins, or seized mechanisms) that isn t immediately visible. A thorough inspection is essential.

### **Conclusion:**The **GM P4620222 exterior door handle latch** is a practical and cost-effective choice for restoring or replacing a faulty latch on 1979 1996 GM vans. Its widespread availability, affordability, and ease of installation make it a strong option for most DIYers. However, buyers should be cautious about rust, wear, and the quality of used parts. If purchasing new or refurbished, prioritize reputable sellers to avoid counterfeit or damaged items.
For vehicles with heavy use or exposure to harsh conditions, consider pairing the latch with a rust inhibitor or additional lubrication to extend its lifespan. If the latch is part of a larger door assembly issue (e.g., misaligned striker plates or worn hinges), address those problems simultaneously for a complete fix.

### **Recommendation:**- **Buy New or Refurbished from a Trusted Source:** Opt for a new ACDelco or GM OEM part, or a refurbished part from a well-reviewed seller (e.g., RockAuto, AutoZone, or a local auto parts store). This minimizes the risk of rust or failure.
- **Inspect Thoroughly if Buying Used:** If purchasing a used latch (e.g., from a salvage yard), disassemble it to check for rust, bent springs, or damaged internal components. Test the latch mechanism by manually engaging and disengaging it.
- **Prepare for Installation:** Gather the necessary tools (screwdrivers, pliers, rubber mallet, and possibly a door panel removal tool if the latch is behind trim). Follow the vehicle s service manual for specific steps.
- **Consider Aftermarket Alternatives:** If the OEM part is difficult to find or expensive, high-quality aftermarket brands like **ACDelco, Dorman, or Spectra** offer reliable drop-in replacements.
- **Address Related Issues:** If the door doesn t latch properly after replacement, check the striker plate alignment, door hinges, and weatherstripping, as these can affect performance.
**Final Verdict:** The GM P4620222 latch is a sound choice for most applications, provided you source it carefully and inspect it for quality. For peace of mind, new or refurbished parts are the safest bet.
This is a heavy part made to last. New other this part has never been mounted to a vehicle but was stored wrong and some rust as seen in pics. Chrome is not perfect.
