Is Your GM Truck or Van Plagued by Bizarre Electrical Problems?
If you’re dealing with erratic power windows, door locks that have a mind of their own, a security light that won’t turn off, or dashboard warning lights flashing for no reason, you’re likely facing a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, and when it malfunctions, it can cause a host of frustrating and difficult-to-diagnose issues. Don’t let a faulty module keep your reliable truck or van off the road. This is the direct, reliable solution you need.

Before replacing your BCM, always perform a full battery and charging system test. A weak battery or poor ground connections (especially the main ground strap from the engine to the frame) can mimic BCM failure. Check these simple items first to potentially save yourself time and money.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and interior lights.
- ✔ The security or anti-theft light stays on, preventing the vehicle from starting.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Inaccurate readings on the instrument cluster gauges.
- ✔ A/C and heater controls not responding correctly.
- ✔ Diagnostic trouble codes related to U-codes (communication errors) or B-codes (body codes).

Installation and Post-Install Procedures
This BCM is typically located under the steering column on pickup models (Silverado, Sierra) or in the center of the dash on van models (Express, Savana). While the physical installation is straightforward, please be aware of potential post-installation steps:
- Airbag System Sync: If your airbag warning light illuminates after installation, a professional scan tool is required 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 recalibration to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.
