### **Pros of buying a Dorman 56396QVDR**
1. **Direct Fitment and Compatibility**
- Dorman is a well-known aftermarket brand that specializes in OEM-quality replacement parts. This module is specifically engineered for the 2003 2006 GMC Sierra 3500 (and Chevrolet Silverado 3500) with the correct pinout and wiring harness connections. It should drop right into place without modification, assuming the original harness is intact.
2. **Reliability and Durability**
- Dorman parts are manufactured to meet or exceed OEM standards, often using similar materials and build quality. The steering column module is a critical component for airbag deployment, traction control, and stability systems, so a reliable replacement ensures proper function without premature failure.
3. **Warranty Coverage**
- Dorman typically offers a 1-year limited warranty on most parts, which provides peace of mind in case of defects. This is comparable to or better than many aftermarket brands.
4. **Cost-Effective Alternative to OEM**
- The Dorman part is significantly cheaper than a brand-new OEM steering column module from GM, often costing 30 50% less. For budget-conscious buyers, this makes it an attractive option without sacrificing quality.
5. **Easy Installation**
- The module is designed to be a straightforward plug-and-play replacement. Most users with basic mechanical skills can install it in under an hour, especially if they have access to a lift or jack stands. No special tools or modifications are usually required beyond disconnecting the battery and unplugging the old module.
6. **Support for Modern Vehicle Systems**
- The steering column module interfaces with the airbag control module (ACM), traction control, and stability systems. A functional replacement ensures all these systems operate correctly, which is critical for safety and drivability.
7. **Positive User Feedback**
- Many reviews from owners of similar GM trucks report that Dorman s steering column modules work reliably after installation. While no part is perfect, the consensus is that this part is a solid choice for the described applications.

### **Cons of buying a Dorman 56396QVDR**
1. **Potential for Counterfeit or Low-Quality Units**
- The aftermarket is rife with counterfeit parts, especially on popular GM truck components. While Dorman is a reputable brand, there is a risk of purchasing a knockoff from unscrupulous sellers (e.g., eBay, Amazon, or unknown online marketplaces). Always buy from authorized dealers, RockAuto, or trusted parts stores to avoid this issue.
2. **No Built-In Learning Function (Like OEM Modules)**
- Some OEM steering column modules have a "learning" feature where they adapt to the driver s steering habits over time. Aftermarket replacements like the Dorman part may not have this capability, which could lead to minor inconsistencies in traction control or stability system behavior. However, this is rarely a significant issue in practice.
3. **Limited Availability of Diagnostic Tools**
- If the new module fails or causes issues, diagnosing the problem may require a scan tool to check for error codes. Some users may need to invest in a GM-specific diagnostic tool (like a Snap-on or Launch X-431) to properly troubleshoot, which adds to the cost.
4. **Possible Compatibility Issues with Aftermarket Harnesses**
- If the original wiring harness is damaged or replaced with a non-OEM harness (e.g., during a steering column rebuild), the Dorman module may not fit or function correctly. Always inspect the harness and connectors before installation.
5. **No Physical Differences from OEM (Potential Confusion)**
- The Dorman part looks identical to the OEM module, which can be confusing if the original was damaged in a way that required removal (e.g., bent pins or broken connectors). Ensure the new part is compatible with the specific year and trim of your truck.
6. **No Long-Term Field Data**
- While Dorman parts are generally reliable, long-term field data (beyond a few years) may not be as extensive as OEM parts, which have been tested on millions of vehicles. However, this is a minor concern for most buyers.
7. **Potential for Software or Calibration Issues**
- In rare cases, replacing the steering column module may trigger a need for a system reset or recalibration (e.g., for the airbag control module). While this is uncommon, it s something to be aware of if the vehicle s warning lights illuminate after installation.
