2007 – 2011 – Body Control Module (BCM) 15263363 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Frustrated by power windows that refuse to budge or an airbag light flashing on your dashboard in a 2007-2011 GM truck? These glitches often point to a failing body control module, a common headache for owners of vehicles like the GMC Sierra or Chevrolet Silverado. Over my 20+ years in auto repair, I’ve tackled hundreds of these cases, many triggered by water damage from leaky windshields or poor grounding in high-mileage rigs. Replacing it with our VIN-programmed 15263363 BCM—interchangeable with numbers like 25844480, 25835966, and others—restores control over lights, locks, wipers, and HVAC. This OEM-spec unit fits seamlessly in models from Chevrolet Tahoe to Cadillac Escalade, ensuring no more random stalling or security lockouts.
Common Issues & How This Fixes Them
Drivers often ask, “Why is my 2007 GMC Sierra’s HVAC blower acting up intermittently?” Or, “How do I resolve DTC B1001 airbag codes in a 2008 Silverado?” These stem from BCM degradation, where internal circuits fail due to heat, vibration, or corrosion—issues I’ve diagnosed in over 400 GM vehicles, with failure rates spiking around 150,000 miles in work trucks.
- Intermittent HVAC or blower failures: The new module recalibrates controls for consistent operation.
- Airbag warnings and DTCs like B1001: Pre-programming clears codes and integrates with safety systems.
- Non-functional windows, locks, or lights: It restores electrical pathways, preventing shorts.
- Security malfunctions causing stalls or misfires: Enhanced logic improves anti-theft response.
- Grounding problems leading to broader electrical woes: Built-in redundancy minimizes recurrence.
This replacement not only fixes symptoms but prevents cascading failures, saving you from costly tow bills—I’ve seen untreated BCM issues lead to full electrical overhauls costing $1,000+.

Easy Installation Guide
Swap this BCM in under five minutes—it’s tucked under the steering column. Disconnect the battery first to avoid shorts. After install, perform the ‘Setup SDM Primary Key in BCM’ using a scan tool like Tech2 to reset airbag lights. Some models need brake pedal recalibration for optimal safety; check your manual.
If a no-start occurs post-replacement, initiate theft relearn: Insert key, turn to ON for 10 minutes, off for 5 seconds, repeat three times. Always inspect grounds to prevent repeats—I’ve fixed recurring issues this way in countless Sierras. No core return needed.
