Restore Full Electrical Function to Your Truck
Are you battling frustrating electrical issues in your truck? Unresponsive power windows, erratic door locks, a malfunctioning HVAC system, or persistent warning lights are common signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can cause a wide range of problems. This genuine OEM-quality Body Control Module, part number 25790509 (interchangeable with 25844480), is the definitive solution for your 2013 Silverado 2500 BCM and a wide range of other 2007-2013 GM trucks and SUVs.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or failing to turn on.
- ✔ HVAC system issues, such as the blower motor not working or temperature controls being unresponsive.
- ✔ An illuminated airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Security system malfunctions, leading to no-start conditions or random alarm activation.
- ✔ Wipers behaving erratically or not working when commanded.
Solving Problems with a Programmed 2013 Silverado 2500 BCM
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We pre-program the module to your vehicle’s specific Vehicle Identification Number (VIN) before shipping. This critical step ensures that the BCM communicates flawlessly with your truck’s other electronic modules right out of the box. You can bypass the expensive trip to the dealership for programming, saving you both time and money. Installation is straightforward, typically located under the driver’s side dashboard near the steering column. While the physical swap is quick, be aware of potential post-installation procedures. If the airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. Additionally, a Brake Pedal Position Relearn may be necessary on some models to ensure proper brake light and stability control operation.
