---
### **Pros of buying a GM 10045832 Wiper Switch Unit**
1. **OEM Compatibility**
The part is designed as an original equipment replacement, meaning it will fit directly into the C4 s wiring harness and mounting location without modifications. This reduces the risk of electrical or mechanical incompatibility issues that can arise with aftermarket alternatives.
2. **Reliability and Durability**
GM s manufacturing standards for OEM parts typically ensure higher durability compared to some lower-quality aftermarket units. The switch is built to withstand frequent use, reducing the likelihood of premature failure, especially in harsh conditions (e.g., salt exposure, humidity, or extreme temperatures).
3. **Consistency with Factory Functionality**
The switch retains the original C4 s wiper control features, including:- **Two-speed intermittent wipers** (if equipped; some models had single-speed).
- **Park (off) position** for the wipers.
- **Compatibility with the C4 s wiper motor and linkage**, ensuring smooth operation without additional adjustments.
The switch also integrates with the C4 s **washers** (if equipped) and may include the **defroster control** (depending on the specific year and trim).
4. **Ease of Installation**
Replacing the wiper switch is a straightforward DIY job for most mechanically inclined individuals. The process involves:- Disconnecting the battery.
- Removing the steering column cover and trim panels.
- Unplugging the old switch and wiring harness.
- Installing the new switch and reconnecting the wiring.
No major tools or specialized knowledge are required, and the procedure typically takes **30 60 minutes**. Many online resources (e.g., YouTube tutorials, Corvette forums) provide step-by-step guidance.
5. **Warranty Coverage**
If purchasing from an authorized GM dealer or a reputable parts supplier (e.g., RockAuto, Summit Racing, or a local auto parts store with a return policy), the part may come with a **limited warranty** (e.g., 12 24 months). This provides peace of mind in case of defects or early failure.
6. **Accessibility and Availability**
The part is widely available through:- **Online retailers** (e.g., RockAuto, Summit Racing, eBay, Amazon).
- **Local auto parts stores** (e.g., AutoZone, O Reilly, NAPA).
- **Corvette specialty shops** or salvage yards (for used units).
This makes it easy to source, even for those without immediate access to a dealership.
7. **Cost-Effective for Long-Term Use**
While the upfront cost may seem higher than some aftermarket options, the OEM switch is built to last the life of the vehicle if maintained properly. This avoids repeated replacements and associated labor costs over time.
8. **Aesthetic and Functional Match**
The switch matches the original C4 s interior styling, which can be important for owners who prioritize authenticity. It also avoids the potential "cheap" look of some aftermarket switches.
---
### **Cons of buying a GM 10045832 Wiper Switch Unit**
1. **Higher Upfront Cost**
The OEM switch is generally **more expensive** than aftermarket alternatives. Prices typically range from **$80 $150**, depending on the source (new vs. used, retailer markup). Aftermarket switches can cost **$20 $60**, making them a more budget-friendly option for some buyers.
2. **Potential for Counterfeit or Low-Quality Parts**
When purchasing online (especially from third-party sellers on eBay or Amazon), there is a risk of receiving a **counterfeit or refurbished part** that may not function as intended. Counterfeit switches may:
- Fail prematurely.
- Have poor build quality (e.g., loose internals, weak springs).
- Not match the original wiring or mechanical specifications.
To mitigate this, buyers should:- Purchase from **verified sellers** with positive reviews.
- Check for **authentic GM part numbers** and packaging.
- Consider buying from **specialty Corvette parts suppliers** (e.g., Corvette Specialties, Corvette Restoration Parts).
3. **Limited Customization**
Unlike some aftermarket switches, the OEM unit does not offer **customizable features** such as:- Adjustable intermittent speeds.
- LED backlighting.
- Additional functions (e.g., rain sensors, variable speed controls).
Owners who desire modern or enhanced features may find aftermarket options more appealing.
4. **Age-Related Wear in Older Units**
If purchasing a **used OEM switch** (e.g., from a salvage yard), there is a risk of:- **Internal corrosion** (common in older switches exposed to moisture).
- **Worn contacts** leading to intermittent operation or failure.
Used switches should be inspected for **signs of rust, pitting, or resistance in the wiring** before installation.
5. **Potential for Compatibility Issues with Modifications**
If the C4 has undergone **aftermarket modifications**, such as:- **Custom wiring harnesses** (e.g., for lighting or audio systems).
- **Steering column replacements** (e.g., aftermarket columns).
- **Electrical upgrades** (e.g., new gauges, alarms).
The OEM switch may not integrate perfectly, requiring additional wiring adjustments or a compatible aftermarket switch.
6. **Limited Aftermarket Support**
While the OEM switch is reliable, troubleshooting issues (e.g., intermittent wiper operation) may require consulting **GM-specific resources** or Corvette forums. Aftermarket switches often come with **detailed installation guides** and community support for common problems.
7. **Environmental Factors**
The C4 s wiper switch is exposed to **dust, moisture, and temperature fluctuations**, which can accelerate wear over time. Even an OEM switch may fail prematurely if:
- The **steering column is not sealed properly** (allowing moisture ingress).
- The **switch is not lubricated** (if it has moving parts).
Regular maintenance (e.g., cleaning contacts, applying dielectric grease) can extend its lifespan.
---
### **Conclusion**
The **GM 10045832 wiper switch unit** is a **reliable, OEM-compatible replacement** for the 1986 1989 Corvette C4, offering durability, ease of installation, and seamless integration with the vehicle s original systems. It is the **best choice for owners who prioritize authenticity, long-term reliability, and a hassle-free replacement process**. However, its **higher cost and limited customization** may deter budget-conscious buyers or those seeking modern features.
For most C4 owners, the OEM switch is the **ideal balance of quality and compatibility**, provided the part is sourced from a **trusted supplier** to avoid counterfeit units. If cost is a major concern, aftermarket switches (from reputable brands like **Delco, Moroso, or Corvette-specific suppliers**) can be a viable alternative, though they may lack the same level of longevity or exact fit.

### **Recommendation**

- **Preferred options**: RockAuto, Summit Racing, or an authorized GM dealer.
