Tired of Chasing Electrical Gremlins in Your GM Truck?
If your 2013 Silverado 2500 is acting possessed—with flickering lights, a dead A/C, or random warning messages—the root cause is often a failing Body Control Module (BCM). As the central command for your truck’s electronics, a faulty BCM can create a host of frustrating and unpredictable problems. This VIN-programmed BCM, a direct replacement for part number 25790509, is the definitive solution to restore order and reliability to your vehicle’s essential functions.
Forget expensive dealership visits and programming fees. We ship this module pre-programmed with your truck’s specific VIN and the latest GM software updates. This ensures it communicates flawlessly with your vehicle’s other systems right out of the box, making for a simple, plug-and-play repair that gets you back on the road with confidence.
Case Study: A Tricky Diagnosis
“A 2011 Sierra 2500 came into my bay with the classic signs: intermittent no-start, wipers turning on by themselves, and a persistent airbag light. The owner had already replaced the battery and checked the alternator. After scanning, I found a dozen communication codes pointing to the BCM. A common point of failure on these GMT900 platforms is the BCM’s internal ground path, which can fail from heat cycles and vibration. We installed one of our VIN-programmed modules, and before tightening the final bolt, I made sure to clean the main chassis ground point nearby. The truck fired right up, all codes cleared, and it’s been running without a single electrical issue since. It’s a 15-minute fix that saves hours of diagnostic headaches.”
Is Your Truck Showing These Signs of BCM Failure?
- ✔ The HVAC blower motor is dead or works intermittently.
- ✔ Power windows, door locks, or interior lights have a mind of their own.
- ✔ The airbag warning light is illuminated, often with DTC B1001 (Setup SDM Primary Key in BCM).
- ✔ Your security system acts up, causing no-start or stalling conditions.
- ✔ Communication DTCs (U-codes) are present when scanning the vehicle.
- ✔ Wipers or other accessories activate without input.
A Straightforward Guide to Your BCM Replacement
- ✔ Safety First: Always disconnect the negative battery terminal and wait a few minutes before starting work.
- ✔ Locate the BCM: On most GM trucks and SUVs of this era, the BCM is located under the driver’s side dashboard, near the steering column. You may need to remove a lower dash panel for access.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unclip or unbolt the old module from its mounting bracket.
- ✔ Install the New Module: Snap the new, pre-programmed BCM into the bracket and firmly reconnect all electrical connectors. Ensure they click into place.
- ✔ Post-Installation Checks: Reconnect the battery terminal. Start the vehicle and test all body functions—lights, windows, locks, wipers, and HVAC. Most functions should work immediately.
- ✔ Special Procedures (If Needed): If the airbag light remains on, a professional scan tool is required to perform the ‘Setup SDM Primary Key’ function. This re-syncs the new BCM with the airbag system. Similarly, a ‘Brake Pedal Position Relearn’ may be needed on some models.

Do I need to have this BCM programmed by a dealer?
No. We pre-program this module to your vehicle’s VIN before shipping. It arrives ready for plug-and-play installation, saving you time and money on dealership programming fees.
What is a core charge?

My airbag light is on. Will this fix it?
