Are you battling frustrating electrical problems in your GMC Savana or other GM vehicle? Intermittent power windows, flickering lights, a malfunctioning security system, or strange warning messages on your dash are all common signs of 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 confusing and unpredictable issues. Restore your vehicle’s functionality and peace of mind with this direct-fit replacement BCM, pre-programmed specifically for your vehicle.
From the Diagnostic Bay
We had a 2011 Express work van come into the shop that was driving the owner crazy. The dome lights would stay on, the power locks would work one minute and not the next, and the radio would randomly shut off. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication loss codes with various accessory modules. This pointed us directly to the BCM. Instead of a dozen separate problems, it was one single point of failure. Installing a VIN-programmed BCM like this one resolved all the issues in a single repair, getting the van back on the road and making money for its owner.
Symptoms of a Failing Body Control Module
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that won’t turn on or off, or flicker randomly.
- ✔ The security system or keyless entry fails to work correctly.
- ✔ Incorrect readings or warning lights on the instrument cluster.
- ✔ HVAC (heating and air conditioning) controls are unresponsive.
- ✔ Communication errors with other vehicle modules, often triggering multiple warning lights.
Your Plug-and-Play Solution: The 2008-2012 Savana 1500 Body Control Module
This isn’t just a replacement part; it’s a complete solution. We take the hassle out of the repair by programming the module to your vehicle’s specific VIN before it ships. This means it arrives loaded with the latest GM software updates, ensuring optimal performance and compatibility. This critical step allows the BCM to communicate correctly with your vehicle’s other electronic systems, saving you a costly trip to the dealership for programming.
Installation and Post-Install Steps
While this module is designed for a straightforward installation, some vehicles may require simple relearn procedures after the new BCM is connected. These are not required for every vehicle but are important to be aware of:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure your brake lights and traction control system function as intended.
Please note: Specific procedures can vary by exact make and model. We always recommend consulting a factory service manual or a qualified technician for guidance.
This module is a direct replacement for a wide range of part numbers, including 15837419, 25892622, 20815898, and many more. Please verify your part number or consult the detailed fitment list on this page to ensure compatibility with your vehicle. With no core charge, you can complete the repair without the need to send your old part back.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and the instrument cluster.
Is this module truly plug-and-play?
Because we program it to your VIN, it’s as close to plug-and-play as possible. However, as noted, some vehicles may require additional relearn procedures for the airbag or brake systems, which may require a professional scan tool.
How do I give you my vehicle’s VIN?
After you complete your purchase, you will need to provide us with your 17-digit VIN. You can typically add it as a note to your order or we will contact you via email to request it before we program and ship the module.
Will this fix my specific electrical problem?
This module will correct issues that are directly caused by a faulty BCM. If you are experiencing several of the symptoms listed, the BCM is a very likely culprit. However, proper vehicle diagnosis is always recommended to rule out other potential causes like wiring or switch failures.
Do I need to return my old part?
No. This product comes with no core charge, so you can keep your original module without any extra fees or hassle.
