Restore Full Electrical Function to Your Vehicle
Is your Buick Lucerne or other GM vehicle acting possessed? Flickering lights, unresponsive power windows, a security system that randomly engages, or dashboard warning lights that have a mind of their own are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems. This replacement Body Control Module is the definitive solution to restore order and get your car’s features working flawlessly again.
This isn’t just a part in a box; it’s a complete, ready-to-install solution. We take the hassle and expense of a dealership visit out of the equation. Upon purchase, simply provide us with your vehicle’s VIN, and our technicians will program the module with the latest official GM software specific to your car’s configuration. This ensures that when the part arrives, it’s ready for a straightforward installation, communicating perfectly with all other systems in your vehicle from the moment it’s connected.
From the Diagnostic Bay
We had a 2008 Buick Lucerne come in that was driving the owner crazy. The radio would switch off, the interior dome lights would flicker while driving, and the power door locks would only work intermittently. The owner had already replaced the battery and checked all the fuses, but the electrical gremlins persisted. After hooking up our diagnostic scanner, we saw multiple communication error codes pointing to the BCM. Instead of a dozen different problems, it was one single point of failure. We installed a VIN-programmed BCM, and instantly, every single issue was resolved. The car behaved like it just rolled off the factory floor. It’s a perfect example of how a failing BCM can mimic a host of other problems.
Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ Malfunctioning windshield wipers or climate control systems.
- ✔ The vehicle’s security system or keyless entry failing to work correctly.
- ✔ False warning lights on the instrument cluster (e.g., ABS, Airbag, Traction Control).
- ✔ Intermittent starting problems or a no-start condition.
- ✔ Rapid battery drain while the vehicle is parked.

Important Post-Installation Information
While this module is programmed for a simple installation, some vehicles may require minor follow-up procedures to ensure all systems are perfectly synchronized. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed. This requires a professional-grade diagnostic tool to sync the new BCM with the airbag system. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor recalibration might be needed to ensure correct operation of the brake lights and traction control system.
These procedures are straightforward for any qualified technician with the appropriate equipment. As always, we recommend consulting your vehicle’s factory service manual for detailed instructions.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls non-engine-related functions like power windows, locks, lights, wipers, security system, and climate controls. When it fails, these systems can behave erratically.
Do I need to program this module after I receive it?
No. The main benefit of our service is that we program the BCM for you before shipping. Simply provide your vehicle’s VIN during checkout, and the module will arrive with the correct software, ready for installation.
Is this a difficult part to install?
For someone with moderate DIY mechanical experience, the physical installation is typically straightforward. The BCM is usually located under the dashboard. However, due to the potential need for post-installation procedures like an airbag sync, we recommend professional installation if you are not comfortable with vehicle electronics.
What happens if my airbag light comes on after installation?
This indicates the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag system (SDM). A technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, we will contact you for your VIN. You can also add it as a note during the checkout process. We cannot ship your part until we have your VIN to ensure correct programming.
Does this part have a core charge?
No, there is no core charge for this module. You can keep your original part without needing to send it back.
