Is your 2008-2012 Chevrolet Express 2500 Van experiencing bizarre electrical issues? Problems like flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are often traced back to 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 cause a wide range of frustrating and difficult-to-diagnose symptoms.
This is a direct replacement Body Control Module, part number 25847588, that solves these issues. The best part? We handle the complicated part for you. Before we ship the module, we will program it to your van’s specific Vehicle Identification Number (VIN). This ensures that the BCM communicates perfectly with your vehicle’s other systems right out of the box, saving you from expensive programming fees and a trip to the dealership.
We had a contractor come in with his ’11 Express 2500 work van. The dome lights would stay on, the radio wouldn’t turn off, and the power locks worked intermittently. He was worried about a massive wiring problem. After a quick scan, we saw communication faults pointing to the BCM. Instead of a lengthy and costly diagnostic and programming session at the dealer, he ordered one of our pre-programmed modules. He installed it himself in under an hour, and all the strange electrical gremlins were gone. It saved him a full day of downtime and hundreds of dollars.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ The security system or keyless entry failing to work correctly.
- ✔ Unexplained warning lights on the dashboard (like the airbag or brake light).
- ✔ The radio or climate control system behaving unpredictably.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire.

Post-Installation Procedures
While this module is programmed for your VIN, some vehicle systems may require a quick relearn procedure after installation to ensure full functionality. These are simple procedures for any qualified technician with a professional scan tool.
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems. This is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary 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.
