Restore Full Electrical Function to Your GM Van or Truck
Are you battling persistent electrical gremlins in your 2004-2007 GMC Savana 3500 Van? Issues like erratic lights, unresponsive power windows, a malfunctioning HVAC system, or a frustrating no-start condition often point to a single culprit: a failing Body Control Module (BCM). This essential component acts as the central nervous system for your vehicle’s body electronics. When it fails, it can cause a cascade of confusing and disruptive problems. This genuine quality GM BCM, interchangeable with part number 10383536 and 15116066, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play repair.
From the Diagnostic Bay
We recently had a 2006 Savana work van come in with a complaint of the battery dying overnight and the blower motor only working on high. The owner had already replaced the battery and the blower motor resistor twice. After a quick scan, we found multiple communication codes pointing to the BCM. A faulty BCM was causing a parasitic draw and overriding the resistor’s function. Installing a VIN-programmed module like this one solved both problems instantly, saving the owner from further costly and incorrect repairs. It’s a classic case of treating the disease, not just the symptoms.
Is Your Savana Van Experiencing These Electrical Issues?
A failing BCM can manifest in numerous ways. If you’re noticing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Power windows, door locks, or interior/exterior lights operating intermittently or not at all.
- ✔ HVAC controls are unresponsive, or the blower motor works erratically.
- ✔ The security system malfunctions, leading to alarm issues or a no-start condition.
- ✔ An airbag warning light is illuminated on the dash, often with DTCs like B1001.
- ✔ Multiple, seemingly unrelated diagnostic trouble codes (DTCs) related to body functions are present.
- ✔ Strange grounding problems or other hard-to-diagnose electrical faults.
The Superior Solution: A VIN-Programmed 2004-2007 Savana BCM
Don’t settle for a generic module that requires expensive dealership programming. We simplify the repair process by programming this module to your vehicle’s VIN before it ships. This ensures that all factory settings and operational parameters are perfectly matched to your Savana, just as it came from the factory. This process loads the latest GM software updates, often resolving issues that were inherent in the original programming. The result is a seamless installation that restores function right out of the box.
Installation and Post-Install Considerations
Installation is straightforward for most DIY mechanics. The BCM is typically located under the steering column or behind the center dash panel. Always disconnect the battery before swapping the modules. While our VIN programming handles the primary setup, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool if the airbag light remains on. This syncs the new BCM with the airbag system. In some cases, a brake pedal position sensor relearn may also be needed. Best of all, there is no core charge, so you can keep your old part without any hassle.
Frequently Asked Questions
What does a Body Control Module do on a GMC Savana?
The BCM is a computer that controls and monitors many of your van’s non-engine related functions. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system.
Is this BCM ready to install out of the box?
Yes. We pre-program the module using your vehicle’s VIN before shipping. This makes the installation plug-and-play, with no need for an expensive trip to the dealership for programming.
Will I need a special tool after installing this module?
In most cases, no. However, if your vehicle’s airbag warning light comes on after installation, a professional scan tool will be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems.
What happens if I don’t replace a failing BCM?
Ignoring a failing BCM can lead to worsening electrical problems, including a no-start condition that can leave you stranded. It can also cause parasitic battery drain and affect safety systems like lights and airbags.
Do I need to return my old part?
No. This module is sold with no core charge, which means you are not required to send your original BCM back to us.
