2003 – 2007 Sierra 1500 Body Control Module 15194170 Programmed To Your VIN BCM

2003 – 2007 GMC SIERRA 1500 BCM (BCM) 15194170 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Ever dealt with your 2003-2007 GMC Sierra 1500 acting up, like doors that won’t lock or interior lights flickering randomly during a rainy drive home? You’re not alone—I’ve seen this in countless trucks where the body control module starts failing after years of exposure to moisture or electrical surges. Questions like “why won’t my Sierra 1500 power windows work intermittently?” or “how to clear BCM-related DTC codes in a 2005 GMC Sierra?” often point to a worn-out BCM. This pre-programmed replacement, part number 15194170, directly addresses those headaches. It comes flashed with the latest GM updates using your VIN for a seamless match, ensuring it clears persistent trouble codes and restores smooth operation. Compatible with numbers like 10383536, 15116066, and others, it fits various GM models including Silverado, Yukon, and Escalade variants from similar years. Beyond basics, this module enhances overall electrical reliability, preventing issues that could leave you stranded or compromise safety features like airbags.

Common Issues & How This Fixes Them

In my two decades fixing GM trucks, BCM failures in 2003-2007 Sierra 1500 models often stem from corrosion under the steering column or voltage spikes from faulty alternators. One common symptom? Erratic door locks that fail to respond, especially in humid conditions, leading to security risks or frustration during daily use. This replacement BCM resolves that by recalibrating communication between locks and the key fob, often clearing DTC codes like U1000 for lost module communication.

Another frequent problem involves malfunctioning interior lights or gauges that dim unexpectedly, which I’ve traced to degraded BCM circuits in high-mileage Sierras used for towing. It disrupts everything from dashboard visibility to accessory power, potentially causing unsafe driving at night. Installing this pre-flashed unit improves electrical stability, ensuring consistent power distribution and better towing reliability without those annoying flickers.

Don’t overlook intermittent wiper failures or power window glitches—common in these years due to BCM software glitches. Owners ask, “what causes my 2006 Sierra 1500 wipers to stop mid-cycle?” It’s usually the module losing sync. This fix integrates the newest GM programming to prevent such lapses, enhancing response times and integrating with systems like the theft deterrent for added peace of mind. Through real shop scenarios, like a client whose Sierra wouldn’t start after a battery swap, we’ve seen how a fresh BCM eliminates no-start conditions tied to immobilizer errors, saving diagnostic time and costs.
