Is your Chevrolet Express or GMC Savana van plagued by frustrating electrical problems? Issues like malfunctioning power windows, erratic interior lights, faulty door locks, or a security system that acts up on its own are often signs of a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body and accessory functions. When it fails, it can cause a wide range of confusing and intermittent symptoms, making diagnosis a challenge.
This is a direct-fit replacement Body Control Module, part number 15819552, for a wide range of GM vehicles, including the 2008-2012 Express 2500 Van. To eliminate the hassle and expense of a dealership visit, we program the module to your vehicle’s specific VIN before shipping. This ensures it communicates correctly with your van’s other systems right out of the box, simplifying the repair process.
Common Symptoms of a Failing BCM
- ✔ Power windows, mirrors, or door locks working intermittently or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The vehicle’s security system or keyless entry failing to operate correctly.
- ✔ Instrument cluster warning lights appearing for no reason.
- ✔ Communication errors with other vehicle modules, leading to a no-start condition.
- ✔ Wipers or radio behaving erratically.

Post-Installation Requirements
While this module is programmed for your VIN, some vehicle systems may require a ‘handshake’ with the new BCM after installation. This is normal and can often be performed with a capable bi-directional scan tool.
- Airbag System Sync: If the airbag (SRS) light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the modules.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure proper brake light and stability control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
