Is your GM truck or van experiencing bizarre electrical issues?
If you’re dealing with flickering lights, malfunctioning power accessories, or a security system that has a mind of its own, a failing Body Control Module (BCM) is the likely culprit. The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating problems. This replacement BCM, part number 15136876, is the definitive solution for restoring your vehicle’s functionality and peace of mind.

Before replacing your BCM, always perform a thorough check of your vehicle’s battery, alternator, and primary ground connections (especially the main chassis and engine grounds). Poor voltage or a weak ground can cause symptoms that mimic a faulty BCM, and verifying these simple items first can save you time and money.
We make the repair process simple. Unlike a trip to the dealership, which involves towing fees and high programming costs, our service provides a BCM that is pre-programmed specifically for your vehicle. Simply provide us with your Vehicle Identification Number (VIN) after purchase, and we will flash the module with the latest GM software updates tailored to your exact configuration. It arrives at your door ready for installation, eliminating the need for expensive specialized tools or dealer intervention.

This module is a direct replacement for a variety of original equipment part numbers, including 15167329, 15194169, 15747545, and more, ensuring a perfect fit for your 2003-2007 GM truck or van. By getting a module programmed to your VIN, you ensure all the original features your vehicle came with will operate correctly.
Common Symptoms of a Failing BCM:
- ✔ Erratic or non-functional power windows and door locks
- ✔ Instrument cluster gauges or warning lights behaving strangely
- ✔ Interior dome lights staying on or not turning on at all

Please note that after installing your new 2003-2007 GM BCM, some vehicles may require additional relearn procedures. For instance, if the airbag light is illuminated, a scan tool procedure called ‘Setup SDM Primary Key in BCM’ may be needed to sync the systems. Similarly, a Brake Pedal Position relearn might be necessary to ensure proper brake light and traction control function. These procedures are typically straightforward for any qualified technician with a professional diagnostic tool.
