Review DORMAN OE SOLUTIONS Hvac Blower Motor Resistor Kit Chevrolet Heating Jo fits C30 1985–1986

The **Dorman SX-9706 HVAC Blower Motor Resistor Kit** is a meticulously engineered replacement solution designed specifically for the **1985 1986 Chevrolet C30** heating and ventilation systems, ensuring optimal performance and reliability for the vehicle s climate control functions. This high-quality kit replaces the original blower motor resistor, a critical component that regulates the speed settings of the HVAC blower motor by controlling the electrical resistance delivered to it. Crafted from durable, corrosion-resistant materials, the Dorman resistor is built to withstand the rigors of daily use, providing smooth, consistent operation across all fan speeds from low to high without the risk of overheating or premature failure. The kit includes all necessary hardware and wiring connections, ensuring a straightforward installation process that minimizes downtime and labor costs. Whether addressing a faulty resistor that causes erratic blower behavior, a complete failure leading to no airflow, or simply upgrading for enhanced longevity, this resistor kit delivers precision-engineered performance tailored to the C30 s specific electrical requirements. With Dorman s reputation for precision manufacturing and compatibility, drivers can trust this component to restore their HVAC system to peak condition, ensuring comfort and efficiency during every drive.

The **Dorman SX-9706 HVAC Blower Motor Resistor Kit** is a common replacement part for the heating and cooling blower motor resistor in 1985 1986 Chevrolet C30 (and similar GM vehicles) when the original resistor fails. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

1. **Direct Fitment and Compatibility**

The Dorman SX-9706 is specifically designed for GM vehicles from the mid-1980s, including the C30. It replaces the original resistor assembly without requiring modifications, ensuring an exact match in terms of wiring and mounting. This reduces the risk of installation errors and compatibility issues.

2. **Reliability and Quality**

Dorman is a well-regarded brand under the **Motorcraft** line (owned by Ford but widely trusted in the aftermarket). Their resistor kits are built to withstand typical operating conditions, reducing the likelihood of premature failure. Many users report long-term performance with minimal issues.

3. **Easy Installation**

The resistor kit comes with clear instructions and is designed for straightforward replacement. It typically requires only basic tools (screwdriver, wire strippers, etc.) and does not necessitate electrical or mechanical expertise. The wiring harness is often pre-assembled, simplifying the process further.

4. **Cost-Effective Solution**

Replacing a faulty resistor is significantly cheaper than overhauling the entire HVAC system or replacing the blower motor itself. The Dorman kit is priced affordably compared to OEM replacements, offering a balance between quality and cost.

5. **Prevents Further Damage**

A failing resistor can cause erratic blower motor operation, excessive heat, or even complete failure of the blower motor. Replacing it promptly prevents secondary damage to the motor or other components, extending the lifespan of the HVAC system.

6. **Widely Available**

Dorman parts are stocked by most auto parts stores (AutoZone, O Reilly, Advance Auto, etc.), making it easy to purchase without long waits or special ordering. Online retailers also carry it with quick shipping options.

7. **Standardized Performance**

Unlike DIY resistor modifications (e.g., soldering or repurposing parts), the Dorman kit provides consistent resistance values and speed settings (typically 1 5 speeds), ensuring the blower motor operates as intended by the manufacturer.

---

1. **Limited Customization**

The resistor kit is a one-size-fits-all solution tailored to the original vehicle specifications. If you want to modify blower speeds (e.g., add a higher speed or adjust resistance for a different feel), you ll need to modify the kit or use an aftermarket resistor with custom settings. This may require soldering or additional components.

2. **Potential for Counterfeit or Low-Quality Copies**

While Dorman is reputable, some online sellers (especially on third-party platforms) may offer counterfeit or inferior copies. Always verify the seller s authenticity and check for genuine Dorman packaging or part numbers to avoid receiving a knockoff.

3. **No Upgrade in Performance**

The Dorman kit replaces the original resistor but does not improve upon it. If your original resistor was adequate but failed due to age, this kit will restore functionality but won t enhance speed, efficiency, or durability beyond the factory design.

4. **Wiring Harness May Need Attention**

While the kit includes the resistor and often the wiring harness, the connectors or surrounding wiring in the vehicle may be worn or corroded. If the harness or terminals are damaged, additional cleaning or replacement may be required, adding to the time or cost of installation.

5. **Blower Motor Health Dependent on Resistor Replacement**

If the blower motor itself is worn or failing, replacing just the resistor won t resolve underlying issues. Symptoms like grinding, humming, or inconsistent speeds could indicate a failing motor, which would require separate attention.

6. **Environmental Factors**

In vehicles exposed to extreme heat, cold, or moisture (e.g., salted roads in winter), resistor kits may degrade faster than expected. While Dorman parts are durable, harsh conditions can still lead to premature failure, though this is true of any resistor.

---

The **Dorman SX-9706 HVAC Blower Motor Resistor Kit** is a practical and reliable choice for replacing a faulty resistor in a 1985 1986 Chevrolet C30. Its direct fitment, ease of installation, and proven quality make it a superior option to DIY repairs or unknown aftermarket parts. The kit restores the blower motor s functionality without significant drawbacks, provided the blower motor itself is in good condition.

However, if you re looking for performance upgrades (e.g., higher speeds or modified resistance), this kit won t suffice, and you d need to explore aftermarket alternatives. Additionally, always ensure you re purchasing from a trusted source to avoid counterfeit parts.

---

For most owners of a 1985 1986 Chevrolet C30 experiencing blower motor resistor failure, **the Dorman SX-9706 is the best choice**. It offers a balance of affordability, reliability, and ease of use. Before purchasing, verify the following:

- Confirm the resistor is the root cause of the issue (test with a multimeter or replace it as a diagnostic step).

- Inspect the blower motor for wear; if it s failing, address it simultaneously.

- Buy from a reputable retailer (e.g., AutoZone, RockAuto, or a local GM parts specialist) to ensure authenticity.

If you re comfortable with minor modifications and want to experiment with blower speeds, research aftermarket resistor kits (e.g., from **Motorcraft, Delphi, or custom-built options**) that offer adjustable resistance. Otherwise, the Dorman kit is the safest and most straightforward solution.
