Restore Full Electrical Function to Your GM Vehicle
Is your Chevrolet Express Van or other GM vehicle plagued by mysterious electrical problems? Flickering lights, malfunctioning power windows and locks, or strange warning messages on your dash are common signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating issues. This replacement Body Control Module, part number 25847588, is the reliable, pre-programmed solution to get your vehicle back in perfect working order.
From the Diagnostic Bay
We had a 2011 Express 1500 work van come in that was driving the owner crazy. The dome lights would stay on, the power locks worked intermittently, and the radio would randomly shut off. He had already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication loss codes with various systems, all pointing to a single culprit. We installed a VIN-programmed BCM, and instantly, all the gremlins were gone. It’s a perfect example of how a single module can cause a cascade of seemingly unrelated problems.
Symptoms of a Failing Body Control Module
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Interior or exterior lights behaving erratically (staying on or not turning on).
- ✔ The security system acting up, or a “Service Theft System” message appearing.
- ✔ Inaccurate gauge readings or warning lights on the instrument cluster.
- ✔ HVAC (heating and air conditioning) controls are unresponsive.
- ✔ Key fob not working to lock or unlock doors.
- ✔ Communication error codes (U-codes) stored in the vehicle’s diagnostic system.

Don’t waste time and money at the dealership with expensive programming fees. We simplify the repair process. When you purchase this module, simply provide us with your vehicle’s 17-digit VIN. Our technicians will flash the BCM with the latest GM-certified software specific to your vehicle’s configuration. This ensures that when the part arrives, it’s ready for installation without the need for a trip to the dealer. This is the most efficient way to replace your faulty 2008-2012 Express 1500 BCM and restore your van’s functionality.
Important Post-Installation Steps
While our programming handles the majority of the setup, some vehicles may require additional synchronization steps after installation. These are simple procedures for any qualified technician with a professional scan tool:
- Airbag System Sync: If the airbag light is on after installation, a “Setup SDM Primary Key in BCM” procedure is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure proper brake light and traction control operation.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions. This includes power windows, locks, interior lighting, security system, wipers, and HVAC controls.

We cannot program and ship your BCM without a valid VIN. Our team will contact you to request the information, but this will delay your order. Please provide it at checkout to ensure fast processing.
Is a core charge required for this part?
No, there is no core charge for this BCM. You can keep your old part.
Will this fix my airbag light?
If the airbag light is caused by a faulty BCM, this part will resolve the issue. However, after installation, you may need a technician to perform the “Setup SDM Primary Key in BCM” procedure to sync the modules and turn off the light.
