### Pros and Cons of Buying a GM 04939195 Wiper Motor (1971 1973 Chevy G20 Van)

1. **Compatibility** This wiper motor is designed specifically for the 1971 1973 Chevy G20 van, ensuring a perfect fit without modification. It is a direct replacement part, which simplifies installation and reduces the risk of compatibility issues.

2. **Reliability** GM parts, especially those from this era, are known for durability when maintained properly. The wiper motor is a mechanical component with fewer electronic components compared to modern systems, which can make it more robust in harsh conditions.

3. **Ease of Replacement** Replacing a wiper motor in these older vans is generally straightforward, requiring only basic tools. The design is simple, and many mechanics or DIYers can handle the job without specialized equipment.

4. **Cost-Effective** Purchasing a genuine GM part (or an aftermarket equivalent) can be more affordable than buying a new van or a full windshield assembly. This is a targeted repair rather than a complete overhaul.

5. **Availability of Parts** While newer, this part is still relatively accessible through auto salvage yards, online marketplaces, or specialty parts suppliers. It is not an obscure or discontinued component, making sourcing easier than for rare or highly specialized parts.

6. **No Software or Electronic Dependencies** Unlike modern vehicles, this wiper motor does not rely on complex electronic controls or software. If it fails, the issue is typically mechanical (e.g., worn gears, broken springs, or motor failure), which is easier to diagnose and fix.

---

1. **Age and Wear** The part itself may be old, even if it is new to you. If sourced from a salvage yard, it could have unseen wear or damage from years of storage or previous use. Testing the motor before installation is advisable.

2. **Limited Availability of New Units** While not impossible, finding a brand-new, unused GM 04939195 wiper motor may be difficult. Most units available are likely used or reconditioned, which could introduce uncertainty about their condition.

3. **Potential for Counterfeit or Mismatched Parts** Some aftermarket or salvage parts may be mislabeled or counterfeit. Ensure the part matches the exact GM number and is compatible with your van s wiring and mounting points to avoid issues like improper fit or electrical problems.

4. **Maintenance Requirements** Older mechanical components may require periodic lubrication or adjustments. If the van is not regularly maintained, the wiper motor could fail sooner than expected due to dust, corrosion, or lack of upkeep.

5. **Wiring or Electrical Issues** Even if the motor is in good condition, the van s wiring harness or connections could be degraded. Corrosion or damaged wires may cause intermittent failures or complete non-functionality of the wipers, requiring additional repairs.

6. **Limited Longevity Compared to Modern Parts** Modern wiper motors are often more efficient and durable due to advancements in materials and design. While this GM part may last years, it may not match the longevity of newer alternatives if the van is used frequently or in harsh environments.

Buying a GM 04939195 wiper motor for your 1971 1973 Chevy G20 van is a practical and cost-effective solution for restoring wiper functionality. The part is reliable, easy to install, and widely compatible, making it a solid choice for those who prioritize simplicity and direct replacement. However, potential buyers should be cautious about the part s condition if sourced from salvage yards, verify wiring compatibility, and be prepared for possible maintenance needs over time.

If the van is used regularly or in extreme conditions (e.g., heavy rain, dust, or salt exposure), consider pairing this repair with a thorough inspection of the wiper linkage, blades, and electrical connections to ensure long-term reliability.

---

1. **Source the Part Carefully** Purchase from a reputable supplier (e.g., RockAuto, eBay with verified sellers, or a trusted salvage yard). Request a return policy or inspection if possible to verify the motor s condition before buying.

2. **Test the Motor Before Installation** If feasible, test the wiper motor in the van to ensure it operates smoothly in both low and high-speed settings. Listen for unusual noises (e.g., grinding or squeaking) that could indicate internal wear.

3. **Inspect the Van s Electrical System** Check the wiring harness, fuses, and connections for corrosion or damage. Clean or replace any compromised components to avoid electrical issues post-installation.

4. **Consider a Replacement Wiper Linkage or Blades** If the wipers are old, replace them alongside the motor to ensure optimal performance. Worn linkages or blades can strain the motor and reduce its lifespan.

5. **Maintain the Van Post-Repair** Regularly lubricate the wiper linkage (if accessible) and clean the windshield to prevent dust or grime from affecting the motor s operation.

6. **Alternative Options** If the part is difficult to find or expensive, explore aftermarket alternatives (e.g., compatible motors from Ford or other GM vehicles) or consider a full windshield assembly replacement if the surrounding components are also worn.

For most owners of a 1971 1973 Chevy G20, the GM 04939195 wiper motor is a worthwhile investment due to its reliability and ease of use. With proper sourcing and maintenance, it will provide years of service.
