Restore Full Functionality to Your Vehicle’s Electronics
Are you battling bizarre electrical issues in your Buick Lucerne or other GM vehicle? Do your power windows have a mind of their own, interior lights flicker randomly, or does the security system trigger for no reason? These frustrating problems often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central nervous system for your car’s body electronics, managing everything from your power locks and windows to your interior lighting and anti-theft system. When it fails, it can create a cascade of confusing and inconvenient symptoms.
This replacement Body Control Module is the definitive solution to restore your vehicle’s electronic systems to perfect working order. We take the hassle and expense out of the repair by programming the module to your vehicle’s specific VIN before we ship it. This means you receive a part that is ready for installation, eliminating the need for a costly trip to the dealership for programming. It arrives loaded with the latest, most stable software updates from GM, ensuring optimal performance and reliability.
Common Symptoms of a Failing BCM
- ✔ Erratic operation of power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ Malfunctioning windshield wipers or washers.
- ✔ Security system alarms triggering randomly or key fob not working.
- ✔ The horn sounding unexpectedly or not working at all.
- ✔ Unexplained warning lights on the instrument cluster.
- ✔ A persistent ‘dead battery’ issue caused by a parasitic draw.

Replacing the BCM shouldn’t be a complicated ordeal. Our process is designed for the everyday vehicle owner and the professional mechanic alike.

This service not only saves you hundreds of dollars in dealer fees but also significantly reduces your vehicle’s downtime.
While the physical installation is often straightforward, some vehicles may require simple post-installation relearn procedures. For instance, if your airbag light illuminates after installation, a professional scan tool may be needed to perform a ‘Setup SDM Primary Key in BCM’ procedure.

Frequently Asked Questions
Why do you need my vehicle’s VIN?
Your Vehicle Identification Number (VIN) allows us to program the Body Control Module with the exact software and settings for your vehicle’s specific options and features. This makes the unit a true plug-and-play solution and ensures all systems communicate correctly after installation.
What does the Body Control Module (BCM) do?
The BCM is a computer that manages the electronic accessories and systems in your vehicle’s body. This includes power windows, locks, interior and exterior lighting, security systems, wipers, and other comfort and convenience features. It is separate from the Engine Control Module (ECM) that manages engine performance.
Is this module difficult to install?
The physical installation is typically straightforward for someone with basic automotive repair experience. The BCM is usually located under the dashboard on the driver’s or passenger’s side. The main challenge is typically the programming, which we handle for you before shipment, simplifying the process immensely.
Do I need to send my old BCM back?
No, there is no core charge for this module. You can keep your original part without any additional fees or hassle.
What should I do if my airbag light comes on after installation?
In some cases, the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a professional mechanic with a compatible diagnostic tool. This will sync the systems and turn off the warning light.
How can I be sure this part fits my car?
This BCM fits a wide array of GM vehicles as listed in the description. The best way to ensure compatibility is to match one of the part numbers listed on this page to the part number on your original module. Providing your VIN during checkout also allows us to double-check and confirm the correct application for you.
