Restore Full Electronic Control to Your GM Vehicle
Are you battling frustrating electrical gremlins in your truck or van? Intermittent wipers, flickering lights, or a non-responsive HVAC system can often be traced back to a single component: a failing Body Control Module. This genuine GM 15116066 BCM is the definitive solution for a wide range of 2002-2007 General Motors vehicles, including the GMC Savana, Chevrolet Express, Silverado, and Tahoe. As the central command center for your vehicle’s body electronics, a functional BCM is critical for everyday operation and safety.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or interior lights operating erratically or not at all.
- ✔ HVAC controls are unresponsive, or the blower motor works intermittently.
- ✔ The security system malfunctions, potentially causing a no-start condition.
- ✔ An illuminated airbag warning light, often accompanied by diagnostic trouble code (DTC) B1001.
- ✔ Wipers behaving unpredictably or failing to turn on/off.
- ✔ Communication errors between various electronic modules.
The Plug-and-Play Solution: A Programmed Savana 2500 BCM
Forget expensive dealership visits and programming fees. We simplify the repair process by pre-programming this module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures that it integrates seamlessly with your existing systems right out of the box. Our programming uses the latest GM software updates, ensuring optimal performance and resolving common software-related DTCs. This Savana 2500 BCM is built to strict OEM standards, guaranteeing reliable performance and longevity. It’s the most efficient way to get your vehicle back to 100% functionality.
Installation and Post-Install Notes
Installation is typically straightforward. On Savana and Express vans, the BCM is located in the center of the dash. On most trucks and SUVs, it’s found under the steering column. The process usually takes just a few minutes. While our VIN programming handles the majority of the setup, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool if the airbag light remains on. Additionally, a Brake Pedal Position Relearn might be needed on certain models. There is no core charge for this part, so you can keep your old module without any hassle.
Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and the climate control system.
Is this part truly plug-and-play?
Yes, because we program it to your vehicle’s VIN before shipping, it is ready for installation without needing a trip to the dealer for programming. In some rare cases, a secondary procedure like an airbag system sync may be required.
How do I know if my BCM is the problem?
Common signs include multiple, unrelated electrical issues happening at once. For a definitive diagnosis, a professional scan tool can read codes directly from the BCM. If you see codes like B1001 or other communication faults, the BCM is a likely culprit.
Where is the BCM located on my 2005 Savana 2500?
On the 2004-2007 Savana and Express vans, the BCM is typically located in the center dash area. On compatible trucks and SUVs like the Silverado or Tahoe, it’s usually found under the driver’s side dash, near the steering column.
What if I order the wrong part?
We recommend verifying your part number before ordering. This BCM, 15116066, is interchangeable with several other numbers including 15136225, 15198116, and 10383536. If you’re unsure, contact our expert support team with your VIN for assistance.
