Restore Full Electrical Function to Your GM Vehicle
Are you battling frustrating electrical problems in your Chevrolet Express or GMC Savana van? Issues like intermittent wipers, unresponsive power windows, a dead HVAC blower, or a persistent airbag light are often traced back to a single component: a failing Body Control Module (BCM). This genuine GM BCM, part number 15198116, is the definitive solution for a wide range of 2002-2007 GM trucks, vans, and SUVs. As the central command center for your vehicle’s body electronics, a functioning BCM is crucial for everyday operation and safety. We make the repair process simple by pre-programming this module to your vehicle’s specific VIN, ensuring a true plug-and-play installation without requiring a trip to the dealership.
From the Diagnostic Bay
We recently had a 2006 Express 2500 work van come into the shop with a list of bizarre symptoms. The radio would randomly shut off, the dome lights wouldn’t work, and the power door locks were completely unresponsive. The owner had already replaced fuses and relays with no success. After connecting our diagnostic scanner, we saw multiple communication error codes pointing to the BCM. Instead of spending hours chasing wires, we installed a VIN-programmed Express 2500 Body Control Module. The moment we reconnected the battery, every single issue was resolved. It’s a common failure point that can mimic a dozen other problems, but the fix is often this straightforward.
Is Your Express 2500 Body Control Module Failing?
A faulty BCM can manifest in numerous ways, often causing confusion for mechanics and owners alike. If you’re experiencing any of the following, a BCM replacement is the likely solution:
- ✔ Unresponsive or erratic power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ HVAC climate control and blower fan malfunctions.
- ✔ An illuminated airbag warning light, often with DTC B1001.
- ✔ Security system faults, leading to no-start or key recognition issues.
- ✔ Intermittent operation of windshield wipers and washers.
- ✔ A cluster of seemingly unrelated diagnostic trouble codes (DTCs).

Post-Installation Procedures
While the installation is plug-and-play, some GM vehicles may require a simple relearn procedure to sync with other modules. If the airbag light remains on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. In some cases, a Brake Pedal Position Relearn may also be necessary. Always consult a factory service manual for your specific model’s requirements.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before it ships. It will arrive ready for immediate installation and operation, saving you time and money.
Where is the BCM located on my 2005 Express 2500 Van?
On the 2004-2007 Express and Savana vans, the Body Control Module is typically located behind the center dash panel, often near the radio or HVAC controls.
Will this part fix my airbag warning light?
If the airbag light is caused by a faulty BCM (often indicated by DTC B1001), this part will resolve the root cause. However, you may need a professional scan tool to perform the ‘Setup SDM Primary Key’ procedure to clear the light after installation.
Is this part difficult to install myself?
The physical replacement is straightforward for someone with basic mechanical skills. It involves removing some dash trim and unplugging a few connectors. The key is being prepared for potential post-installation electronic relearn procedures.
What happens if I forget to provide my VIN when ordering?
We cannot ship the module without a VIN. Programming is essential for the part to function correctly in your vehicle. We will contact you to obtain the VIN if it is not provided at checkout.
Does this module interchange with other part numbers?
Yes, this BCM is a direct replacement for numerous part numbers, including 15116066, 15136225, 15198116, 15257043, and others.
