Is Your Vehicle Acting Possessed? It Could Be The BCM.
Are you dealing with a frustrating array of electrical gremlins in your Chevrolet Caprice or other GM vehicle? Power windows with a mind of their own, intermittent door locks, dashboard lights flickering like a holiday display, or a security system that randomly prevents your car from starting? These aren’t just annoyances; they are classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, coordinating everything from your interior lights and power seats to the anti-theft system. When it starts to fail, it can cause unpredictable and widespread issues that can be difficult to diagnose.
From the Diagnostic Bay
We had a 2012 Impala come in that was driving the owner crazy. The horn would honk randomly, the radio would shut off, and the interior dome light would stay on, draining the battery overnight. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw a flood of communication errors pointing towards the BCM. Water intrusion from a leaky windshield cowl seal had corroded the module’s internal circuits. Replacing the BCM with a pre-programmed unit like this one, and fixing the leak, resolved all the bizarre electrical issues in one go. It’s a perfect example of how one single component can create system-wide chaos.
Symptoms of a Failing Body Control Module
- ✔ Erratic or non-functional power windows, locks, and mirrors.
- ✔ Interior or exterior lights staying on, not turning on, or flickering.
- ✔ The security or anti-theft system engaging improperly, causing a no-start condition.
- ✔ Inconsistent or non-working dashboard gauges and warning lights.
- ✔ Problems with the keyless entry or remote start systems.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ A persistent battery drain that leaves you stranded.
The Direct-Fit, Programmed Solution
Don’t let a faulty BCM control your driving experience. This replacement Caprice Body Control Module is the definitive solution to restore your vehicle’s electronic stability. We take the guesswork and dealership hassle out of the equation. Unlike a generic module from a parts store, this unit is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures that all the factory-installed options and security features communicate correctly, making for a much smoother installation process. Simply provide us with your VIN upon purchase, and we’ll handle the complex programming, loading the latest GM software updates for optimal performance and reliability.
Installation and Post-Install Notes
Installation is straightforward for those with mechanical experience. However, please be aware of a few potential post-installation procedures that may be required depending on your specific vehicle:
- Airbag System Sync: If the airbag warning light illuminates after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control functionality.
There is no core charge for this module. You can keep your old part without the hassle of returning it.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions. This includes power windows, power locks, interior and exterior lighting, the anti-theft system, wipers, and other comfort and convenience features.
Do I need to program this BCM?
No. We handle the programming for you before we ship the part. You just need to provide your vehicle’s VIN at checkout or by message, and we will flash the module with the latest GM software specific to your car.
How do I find and provide my VIN?
Your 17-digit VIN can be found on your vehicle’s registration, insurance card, or on a plate on the driver’s side dashboard visible through the windshield. Please provide this number to us after you complete your purchase.
What if my airbag light comes on after installation?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed by a technician with a compatible high-level scan tool to resolve this.
Is there a core charge or do I need to send my old part back?
No, there is absolutely no core charge. You can keep your original module without any obligation to return it.
