Restore Full Electronic Functionality to Your Vehicle
Is your Buick Lucerne or other GM vehicle suffering from strange and unpredictable electrical problems? Flickering lights, malfunctioning power windows, a faulty security system, or even a car that won’t start can often be traced back to a single component: the Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a failing BCM can cause widespread issues that are frustrating and difficult to diagnose. This replacement Body Control Module is the definitive solution to restore your car’s performance and reliability.
From the Diagnostic Bay
We had a 2008 Buick Lucerne come into the shop with a list of bizarre symptoms. The owner said the interior lights would stay on, the radio would randomly shut off, and the remote key fob worked intermittently. After checking the usual suspects like fuses and wiring, our diagnostics pointed to an internal failure in the BCM. Instead of a costly trip to the dealer, we installed one of our VIN-programmed modules. The installation was straightforward, and instantly, all the ghost-in-the-machine problems were gone. The customer was thrilled to have their car back to normal without the dealership hassle.
Symptoms of a Failing Body Control Module
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Intermittent issues with the radio or instrument cluster gauges.
- ✔ Security system faults or the anti-theft light staying on.
- ✔ Remote keyless entry (fob) failing to lock or unlock the doors.
- ✔ A vehicle that cranks but refuses to start due to security system communication failure.
- ✔ False warning lights appearing on the dashboard.

Important Post-Installation Information
While our BCMs are designed for a straightforward installation, some vehicles may require additional steps to ensure all systems communicate correctly. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and traction control function.
Always consult your vehicle’s factory service manual or a qualified technician for specific instructions.
