Is Your Chevrolet Caprice Experiencing Electrical Gremlins?
If you’re dealing with bizarre and frustrating electrical issues in your 2011, 2012, or 2013 Chevrolet Caprice, a failing Body Control Module (BCM) is often the culprit. The BCM acts as the central command center for your vehicle’s body electronics. When it begins to fail, it can create a cascade of problems that seem unrelated, making diagnosis a nightmare for even seasoned mechanics. From flickering lights and malfunctioning power windows to a vehicle that refuses to start, a faulty BCM can bring your daily drive to a halt.
From the Diagnostic Bay
We recently had a 2012 Caprice PPV (Police Pursuit Vehicle) in the shop with a classic case of BCM failure. The officer reported that the interior lights would stay on intermittently, the power locks would cycle on their own, and occasionally, the car wouldn’t recognize the key fob. After checking the basics—battery, grounds, and fuses—we connected our diagnostic scanner. It revealed multiple communication loss codes with various modules, all pointing back to the BCM as the source of the network interference. Replacing the module with a properly programmed unit resolved all the ghost-like issues instantly, getting the vehicle back in service the same day.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Malfunctioning windshield wipers or horn.
- ✔ Security system faults or anti-theft light staying illuminated.
- ✔ Dashboard warning lights appearing for no reason.
- ✔ Problems with the keyless entry or remote start system.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire up.
- ✔ Communication errors with other vehicle modules (DTC U-codes).
The Direct-Fit, Programmed Solution for Your Vehicle
Don’t let a faulty module keep your car off the road. This Body Control Module is a reliable, direct-fit replacement for your vehicle, solving these frustrating electrical problems and restoring full functionality. The critical advantage of our service is that we program the module specifically for your vehicle before it ships. Simply provide us with your Vehicle Identification Number (VIN) after purchase, and our technicians will flash the BCM with the latest GM-certified software and calibrations that match your Caprice’s exact options and features. This eliminates the need for an expensive trip to the dealership for programming, saving you time and money.
Understanding Your 2011-2013 Caprice BCM Replacement
Installing this pre-programmed 2011-2013 Caprice BCM is a straightforward process. Once you receive the module, the physical swap is typically simple, involving disconnecting the battery, accessing the module (often located in the driver’s or passenger’s side dash area), and transferring the electrical connectors. However, as with any modern vehicle computer, some post-installation steps may be necessary to ensure all systems communicate correctly.
Post-Installation Procedures
While we handle the primary programming, certain security and sensor systems may need to be re-synced with the new BCM. Please be aware of the following potential requirements:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to synchronize the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a recalibration of the brake pedal position sensor might be necessary. This ensures the brake lights and traction control system function as intended.
Disclaimer: Specific procedures can vary. We always recommend consulting a factory service manual or a qualified technician for guidance.

What is a Body Control Module and what does it do?
The Body Control Module (BCM) is a computer that manages and controls many of your vehicle’s non-engine related electronic functions. This includes power windows, door locks, interior and exterior lighting, the security system, wipers, and communication between various electronic modules.
Where is the BCM located on a 2011-2013 Chevrolet Caprice?
On the 2011-2013 Caprice, the Body Control Module is typically located inside the cabin, behind the dashboard on the driver’s side, near the steering column. Always consult a service manual for the exact location and removal procedure for your specific vehicle.
