Is Your GM Vehicle Acting Possessed?
Are you dealing with a frustrating mystery of flickering lights, power windows with a mind of their own, or a security system that randomly goes off? Before you blame ghosts in the machine, the real culprit is likely a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, when the BCM starts to fail, it can cause a cascade of bizarre and unpredictable problems. I’ve seen work vans like the Savana 3500 come into my shop completely sidelined by these issues, costing the owner time and money.
This isn’t just an inconvenience; it can be a major disruption. That’s why we offer this fully programmed Body Control Module, a direct-fit solution designed to restore order to your vehicle’s electronics and get you back to work without the hassle and expense of a dealership visit.
Common Symptoms of a Failing BCM:
- โ Intermittent or non-functional power windows, locks, and mirrors.
- โ Erratic interior or exterior lighting behavior.
- โ The security system or alarm activating for no reason.
- โ A/C and climate control systems not responding correctly.
- โ Warning lights on the dashboard (like the airbag light) that won’t turn off.
- โ Communication errors with other modules, leading to a no-start condition.

Expert Pro Tip: Don’t Mistake a Bad BCM for a Bad Battery
In my 20+ years of diagnostics, one of the most common misdiagnoses for BCM failure is a faulty battery or alternator. A failing BCM can cause a parasitic draw that drains the battery overnight. Many owners replace the battery, only to have the problem return. Before you spend money on a new battery, have a technician perform a parasitic draw test. If the draw disappears when the BCM fuse is pulled, you’ve found your culprit. This simple diagnostic step can save you hundreds of dollars and a lot of frustration.
Simple Installation Process
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most Savana and Express vans, the BCM is located in the center dash area. On other GM models, it may be under the steering column or on the left side of the dash. A quick search for your specific model will confirm its location.
- Swap the Module: Carefully unplug the electrical connectors from the old BCM. Remove any mounting bolts or clips and take out the old unit. Install the new, pre-programmed module in its place and securely reconnect all electrical connectors.
- Reconnect Power: Reattach the negative battery terminal.
Critical Post-Installation Steps
After installing your new 2008-2012 Savana 3500 Body Control Module, a few final procedures are necessary to ensure all systems function correctly. These steps require a professional-grade diagnostic scan tool.
- Airbag System Reset: To clear the airbag warning light, the ‘Setup SDM Primary Key in BCM’ procedure must be performed. This re-establishes communication between the new BCM and the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Sensor Relearn: Some vehicles require the Brake Pedal Position (BPP) sensor to be recalibrated. This ensures the brake lights and stability control systems receive accurate input from the brake pedal.
Note: If you are not comfortable performing these procedures, we strongly recommend seeking assistance from a qualified local mechanic.
