Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your vehicle? Flickering lights, unresponsive power windows, a malfunctioning security system, or a persistent airbag light are common signs of a failing Body Control Module (BCM). This genuine GM BCM, part number 25844480, is the definitive solution for your 2007-2013 Chevrolet Silverado, GMC Sierra, Tahoe, Yukon, or Cadillac Escalade. As the central nervous system for your vehicle’s body electronics, a fully functional BCM is critical for proper operation. We take the guesswork out of the repair by pre-programming this module to your vehicle’s specific VIN, ensuring a seamless, plug-and-play installation without requiring a costly trip to the dealership.
Symptoms of a Failing Body Control Module
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or failing to turn on.
- ✔ HVAC and climate control systems behaving erratically or not responding.
- ✔ Airbag warning light illuminated on the dash, often with DTC B1001.
- ✔ Vehicle security system malfunctions, causing no-start conditions or false alarms.
- ✔ Wipers operating randomly or not parking in the correct position.
- ✔ Unexplained battery drain due to the BCM not entering sleep mode.
Installing Your 2013 Silverado 2500 BCM
This module is engineered for a straightforward installation, typically located under the driver’s side dashboard near the steering column. The process is simple: disconnect the negative battery terminal, remove the lower dash panel for access, unplug the electrical connectors from the old BCM, swap in the new module, and reconnect everything. Since we program it to your VIN, no further dealer intervention is needed for basic functionality. However, please note the following potential post-installation procedures:
- Airbag System Sync: If the airbag light remains on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
This module is a direct replacement for a wide range of part numbers, including 15926094, 25835966, 15878753, 20939137, and 22860591. Restore your vehicle’s reliability and functionality with this essential component.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors numerous body electronic functions. This includes power windows, door locks, interior and exterior lighting, wipers, the security system, and HVAC controls.
Do I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. This makes it a plug-and-play installation, saving you the time and expense of a dealership visit for programming.
Where is the BCM located on my 2013 Silverado 2500?
The BCM is typically located under the driver’s side dashboard, often to the left of the steering column. Access usually requires removing the lower dash trim panel.
What if my airbag light is on after I install the new BCM?
This is a common security feature. You will need a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with your vehicle’s existing airbag module to clear the light.
Is there a core charge for this part?
No, there is no core charge. You can keep your old module without needing to send it back to us.
