Ever dealt with your GMC Sierra 2500’s power windows acting up on a rainy job site, or the interior lights flickering unpredictably during a long haul? These frustrations often point to a failing Body Control Module (BCM), especially in 2003-2007 models exposed to harsh weather and heavy towing.

It swaps seamlessly with compatible numbers like 10383536, 15116066, and others, fitting a range of GM vehicles including Silverado pickups, Yukons, and even Hummer H2s from similar eras. This isn’t just a replacement—it’s a reliable fix that enhances overall vehicle reliability, from better door lock response to improved towing stability by ensuring consistent power distribution.

Common Issues & How This Fixes Them
In my two decades fixing GM trucks, BCM failures in 2003-2007 Sierra 2500s often stem from moisture ingress or electrical overloads during towing. One classic symptom? Dashboard warning lights staying on, triggered by communication errors that set DTC codes like B1370 for device ignition issues. This can lead to non-functional accessories, compromising safety on highways. Another headache is erratic power door locks or windows, caused by corrupted module data—I’ve diagnosed this in vehicles with high mileage, where vibrations from rough terrain accelerate wear. Then there’s the intermittent no-start condition, often linked to anti-theft system glitches, leaving you stranded at job sites. Our pre-programmed BCM tackles these head-on by resetting internal protocols and applying GM’s newest firmware, which stabilizes voltage regulation and clears those pesky codes. For instance, a client with a 2005 Sierra hauling trailers reported constant fuse blows; after installation, his system ran smoothly, even improving towing reliability by maintaining steady power to trailer brakes. Plus, it addresses subtler problems like malfunctioning remote keyless entry, ensuring your truck responds reliably in cold mornings.
Easy Installation Guide
- Provide your VIN right after purchase so we can program the BCM precisely for your 2003-2007 GMC Sierra 2500.
- Disconnect the battery to ensure safety, then locate the BCM under the steering column (or center dash in some van models).
- Remove the old unit by unplugging connectors and unbolting it—note any corrosion for future prevention.
- Install the new BCM, reconnect everything securely, and reconnect the battery.
- Perform necessary relearns: If a no-start occurs due to theft system, cycle the key from off to on (without starting) 3-4 times, waiting 10 minutes each cycle until the security light turns off.
- Reset the airbag warning light by using a diagnostic tool for the ‘Setup SDM Primary Key in BCM’ procedure; also, recalibrate the brake pedal if your model requires it for optimal braking response—consult your manual or a pro for specifics.
