Restore Full Functionality to Your GM Vehicle’s Electronics
Are you battling frustrating electrical gremlins in your 2008-2012 Savana 2500 Van? Issues like flickering lights, malfunctioning power windows or locks, erratic dashboard warnings, or even a no-start condition can often be traced back to a single component: a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can cause a wide array of confusing and disruptive problems. This replacement Body Control Module, part number 15948438, is the definitive solution to restore your vehicle’s performance and reliability.
From the Diagnostic Bay
We had a contractor come in with his ’11 Savana work van. He was losing time and money because his van would intermittently refuse to start, and the interior lights would flicker like a disco. He’d already replaced the battery and alternator. After a quick scan, we saw multiple communication codes pointing to the BCM. We installed a VIN-programmed module just like this one. The van started right up, all the lights worked perfectly, and he was back on the job the same afternoon. A faulty BCM can mimic many other problems, but replacing it is often the direct fix.
Is a Failing Body Control Module Causing Your Problems?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic or non-working interior and exterior lights.
- ✔ Security system faults or the vehicle not recognizing your key fob.
- ✔ Dashboard warning lights (like the airbag or brake light) staying on.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire up.
- ✔ Problems with the radio, climate control, or other interior accessories.

Installation and Post-Install Notes
While this module is designed for a straightforward installation, some vehicles may require simple post-installation relearn procedures. This is a normal part of the process when replacing a major electronic component.
- Airbag System Sync: If the 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: Some models may require a brake pedal position sensor recalibration to ensure correct brake light operation and to satisfy the traction control system.
There is no core charge for this module. You can keep your original part.
