Are you experiencing frustrating electrical issues with your GMC Savana 2500 Van? Problems like flickering lights, malfunctioning power windows and locks, or strange warning messages on your dashboard are often caused by a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can create a host of unpredictable problems. This replacement Body Control Module is the reliable, straightforward solution to restore your van’s functionality and get you back to work with confidence.
This isn’t just a part; it’s a complete solution. We program the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This means it arrives at your door with the latest GM software updates already installed, eliminating the need for an expensive trip to the dealership for programming. Simply provide your VIN at checkout, and we’ll handle the rest.
From the Diagnostic Bay
We had a contractor bring in his ’11 Savana 2500 work van with a list of bizarre symptoms. The dome lights would stay on, the driver’s side power lock wouldn’t work, and the radio would randomly shut off. He’d already replaced the battery and checked fuses with no luck. After connecting our diagnostic tool, we saw multiple communication errors pointing to the BCM. Instead of a complex wiring chase, we installed a VIN-programmed BCM. In under an hour, every single one of his electrical gremlins was gone. It’s a common failure point on these workhorses, but thankfully, it’s a very direct fix.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that won’t turn on or off, or flicker intermittently.
- ✔ Malfunctioning instrument cluster gauges or warning lights (like the security light).
- ✔ The vehicle’s security system engaging randomly or preventing the engine from starting.
- ✔ Radio or climate control systems behaving unpredictably.
- ✔ A ‘Service Electrical System’ message appearing on the driver information center.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. It arrives ready for installation, saving you time and money.
How do I provide my VIN?
You can enter your vehicle’s 17-digit VIN during the checkout process or send it to us with your order number after purchase. We cannot ship the part until we have your VIN.
Is this a simple plug-and-play installation?
For most vehicles, yes. You disconnect the battery, swap the old module with the new one, and reconnect the battery. However, some models may require a ‘relearn’ procedure for the airbag or brake systems, which may require a professional scan tool.
What happens if my airbag light is on after installation?
This indicates the new BCM needs to be synced with the airbag system’s Supplemental Deployment Module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a compatible high-level scan tool to resolve this.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module without needing to send it back.
