The **Chevy Silverado 3500 (2014 2019) UAC HVAC Blower Motor Resistor (SW11355C)** is a precision-engineered component designed to regulate the airflow speed within your vehicle s climate control system, ensuring optimal comfort and efficiency. This high-quality resistor is specifically tailored to fit the **2014 through 2019 Chevrolet Silverado 3500 HD models equipped with the UAC (Universal Air Conditioning) HVAC system**, making it a direct, OEM-replacement part that maintains factory performance without compromising on reliability. Crafted from durable, corrosion-resistant materials, this resistor is built to withstand the demanding conditions of heavy-duty truck applications, including extreme temperatures, prolonged use, and exposure to road debris or moisture. Its seamless integration with the **blower motor assembly** allows for smooth, incremental adjustments to airflow from a gentle breeze to full-force ventilation by controlling the electrical resistance and current flow to the motor windings. This ensures consistent, quiet operation across all blower speeds, reducing strain on the motor and extending the lifespan of your HVAC system. Whether you re hauling heavy loads in scorching heat or navigating cold climates, this resistor guarantees precise control over cabin temperature and airflow, enhancing both passenger comfort and system longevity. Ideal for original equipment replacement (OER) or upgrade projects, the **SW11355C** is a trusted solution for mechanics and DIY enthusiasts seeking a dependable, no-fuss part that restores or maintains the performance of your Silverado s climate control system.
### **Pros and Cons of buying a UAC HVAC Blower Motor Resistor (SW11355C) for a 2014 2019 Chevy Silverado 3500**
#### **Pros:**1. **Direct Fitment** The SW11355C is a known OEM replacement part for the 2014 2019 Chevrolet Silverado 3500 HD, ensuring compatibility without modification.
2. **Reliability** UAC (Underhood Auxiliary Company) is a reputable aftermarket supplier with a history of producing high-quality HVAC components, reducing the risk of premature failure.
3. **Cost-Effective Repair** Replacing the blower motor resistor is significantly cheaper than installing a new blower motor assembly, which can cost several hundred dollars.
4. **Easy Installation** The resistor is typically located near the HVAC control module or blower motor and can be replaced with basic tools (no wiring harness replacement required).
5. **Prevents Further Damage** A failing resistor can cause erratic blower motor behavior, leading to overheating or complete failure. Replacing it early avoids more extensive HVAC system issues.
6. **Warranty Coverage** Many aftermarket parts, including UAC components, come with warranties, providing peace of mind against defects.
#### **Cons:**1. **Potential Counterfeit Risk** Some third-party sellers may offer fake or low-quality replicas, which could fail quickly or cause electrical issues. Buying from a trusted retailer (e.g., RockAuto, Amazon, or a local auto parts store) mitigates this risk.
2. **Limited Lifespan** While the resistor itself is durable, it is a wear item and may eventually fail again, especially if the blower motor is already struggling.
3. **DIY Difficulty for Some** If the vehicle s wiring or HVAC system is complex (e.g., due to previous modifications), locating and replacing the resistor may require patience or professional assistance.
4. **No Long-Term Guarantee** Unlike a full HVAC system replacement, this is a band-aid solution. If the blower motor is failing alongside the resistor, a more comprehensive repair may be needed soon.
5. **Price Sensitivity** While affordable, some buyers may prefer a slightly more expensive but higher-end resistor (e.g., from a brand like Dorman or Delphi) for perceived longevity.

### **Conclusion:**The **UAC SW11355C blower motor resistor** is a **practical and cost-effective solution** for fixing HVAC blower speed issues in the 2014 2019 Chevy Silverado 3500 HD. It offers a straightforward repair with minimal downtime and avoids the higher cost of a full blower motor replacement. However, it is not a permanent fix eventual failure is possible, especially if the blower motor is already degraded.
If the resistor is the **only failing component** and the blower motor operates smoothly at all speeds, this part is a **strong recommendation**. If the blower motor itself is noisy, stalling, or failing intermittently, consider replacing it alongside the resistor for a more durable solution.
---
### **Recommendation:**- **Buy from a trusted source** (e.g., RockAuto, Amazon, or a local auto parts store with return policies) to avoid counterfeit parts.
- **Verify symptoms** if the blower motor is the only issue, this resistor is a **good, budget-friendly fix**.
- **Consider a blower motor replacement** if the motor is also failing, as this prevents future resistor-related problems.
- **Test the repair** after installation by cycling all blower speeds to ensure proper function.
**Final Verdict:** **Worth purchasing** for the described issue, provided the blower motor is otherwise functional. For long-term reliability, address the motor if it shows signs of wear.
