Are you experiencing a cascade of bizarre electrical problems in your GM truck or SUV? Flickering lights, unresponsive power windows, a malfunctioning security system, or an HVAC system with a mind of its own are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can make driving frustrating and unsafe. This OEM-quality replacement BCM, part number 15137395, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play installation.

From the Diagnostic Bay
n
We had a 2005 Silverado 2500 come in with a classic BCM failure case. The customer complained of intermittent no-start conditions, the radio staying on after the key was removed (draining the battery), and the driver’s side power window not working. After confirming power and grounds were good, we pinpointed the BCM. Instead of a costly trip to the dealership for a new module and programming, we installed one of our VIN-programmed units. The installation took less than 10 minutes, and all the strange electrical gremlins were gone instantly. The customer was back on the road the same day, saving both time and money.

n
Physical installation is straightforward. The BCM is typically located under the driver’s side dashboard, near the steering column. Simply disconnect the battery, remove the old module, plug this one in, and reconnect the battery. For most users, the process is complete. However, in some cases, additional steps may be needed:

- Airbag System Sync: If the airbag light remains on after installation, a technician will need to use a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and stability control function.
