Is Your Buick Lucerne Experiencing Strange Electrical Problems?
The Body Control Module, or BCM, is the central command center for your vehicle’s electronic accessories. When it begins to fail, it can cause a wide range of confusing and frustrating issues. From power windows that won’t budge to a security system that acts on its own, a faulty BCM can make your car feel unreliable. This isn’t just an inconvenience; it can affect the safety and functionality of your vehicle. We offer a dependable, pre-programmed solution to get your car back to normal.
We had a 2008 Buick Lucerne come into the shop with a laundry list of bizarre symptoms. The radio would turn on and off randomly, the driver’s side power lock was dead, and the dome light would flicker while driving. The owner had already replaced the battery and checked fuses with no luck. After connecting our diagnostic scanner, we saw multiple communication errors pointing towards the BCM. Instead of a costly and time-consuming replacement at the dealership, we installed one of our VIN-programmed modules. The car was back to 100% functionality in under an hour, resolving all the ghost-like electrical issues at once.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ Erratic behavior from the car alarm or security system.
- ✔ Instrument cluster warning lights appearing for no reason.
- ✔ Radio or climate control systems malfunctioning.
- ✔ Key fob not being recognized or working inconsistently.
- ✔ Vehicle not starting due to security system immobilization.

Post-Installation Procedures
While this module is designed for straightforward installation, some vehicles may require additional steps to ensure all systems communicate correctly. These are known as relearn procedures and can sometimes be necessary after replacing a major electronic component.
- Airbag System Sync: If your 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: On some models, a brake pedal position sensor recalibration might be required to ensure your brake lights and traction control system function as intended.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before we ship it to you. It arrives ready to be installed, saving you time and money.
How do I provide my VIN?
You can add your 17-digit VIN to the notes section during checkout. If you forget, we will contact you via email to request it before we can program and ship your order.
My original part number is different. Will this still fit?
Yes, this module replaces a large number of original GM part numbers. Please check the extensive list in the description to confirm that your part number is included.
What tools are needed for installation?
Installation typically requires basic hand tools like a socket set and trim removal tools to access the module. However, as noted, a professional-grade scan tool may be required for post-installation relearn procedures.
What if the airbag light comes on after I install it?
This indicates that the BCM needs to be synced with the airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed by a qualified technician with a compatible diagnostic tool.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module.
