Are you battling persistent and frustrating electrical problems in your GM truck or van? Intermittent power windows, flickering lights, or a security system that acts on its own are common 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 create a cascade of confusing issues. This replacement BCM, part number 15136224, is the definitive solution to restore full functionality and reliability to your vehicle.
We make the repair process simple. Unlike a trip to the dealership, which involves high costs for the part and separate programming fees, our BCM arrives at your door pre-programmed to your vehicle’s specific VIN. We flash it with the latest GM software updates, ensuring optimal performance and compatibility right out of the box. This plug-and-play solution eliminates the need for expensive diagnostic tools or a visit to a technician for programming, getting you back on the road faster.
We had a 2005 Silverado 2500 in the shop where the owner had replaced the driver’s side window switch three times, convinced it was faulty. The window would work one day and not the next. After checking the wiring, we suspected the BCM. A quick swap with a known-good unit confirmed our diagnosis. The original BCM had an internal fault that was intermittently cutting power to the switch. This pre-programmed module saves you from that kind of diagnostic headache and parts-chasing.
Is Your GM Truck or Van Showing These Symptoms?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, a failing BCM is the likely culprit:
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system engaging randomly or preventing the vehicle from starting.
- ✔ Horn honking unexpectedly.
- ✔ Inaccurate readings on the instrument cluster gauges.
- ✔ ‘Service Electrical System’ or similar warnings on the driver information center.
Simple Installation & Post-Install Requirements
Replacing your 2003-2007 GM BCM is a straightforward process. The module is typically located under the steering column in pickups or in the center dash area in vans. Once the new module is installed, it’s ready to go. However, in some cases, additional vehicle-specific relearn procedures may be necessary.
- Airbag System Sync: If your airbag warning light illuminates after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light and traction control operation.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
Do I need to program this module?
No. We pre-program the BCM to your vehicle’s VIN before shipping. It arrives ready for installation, saving you a trip to the dealership and additional programming fees.

For most DIYers with basic tools, installation is straightforward. In pickups, it’s usually under the driver’s side dash. In vans, it’s often in the center dash. Always disconnect the battery before starting work.
What is the ‘Setup SDM Primary Key’ procedure?
This is a security procedure that syncs the new BCM with your vehicle’s airbag system (SDM). It’s only required if the airbag light comes on after installation and must be done with a professional-grade scan tool.
