Restore Full Electrical Function to Your Buick Enclave
Is your 2013-2017 Buick Enclave experiencing a host of frustrating electrical problems? From power windows that won’t budge to dashboard lights that have a mind of their own, a failing Body Control Module (BCM) is often the culprit. As the central hub for your vehicle’s body electronics, its failure can cause widespread and confusing issues. In my 20+ years as a diagnostician, I’ve seen faulty BCMs turn a reliable luxury SUV into a source of daily headaches. This replacement BCM, part number 22820314, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN.
We take the guesswork and high dealership costs out of the equation. Simply provide us with your VIN during checkout, and our technicians will flash the module with the latest GM software updates. This ensures it communicates perfectly with your Enclave’s other systems right out of the box, restoring the functions you depend on. This isn’t just a replacement part; it’s a direct path to getting your vehicle back to 100% operational status without the need for expensive programming appointments.
A Technician’s Notebook: The Haunted Traverse
A customer brought in a 2015 Traverse—a vehicle that shares its platform with the Enclave—with a list of symptoms that sounded like a ghost story. The radio would change stations on its own, the interior dome lights would flicker while driving, and the liftgate would occasionally refuse to open. There were no engine codes, just a handful of intermittent communication (U-code) faults. After ruling out wiring and grounding issues, we focused on the BCM. We swapped in a pre-programmed module, and like flipping a switch, every single phantom issue vanished. This is a classic case where the BCM, the vehicle’s electronic nerve center, begins to break down, causing chaos across multiple, seemingly unrelated systems. This is precisely the problem our 2013-2017 Enclave BCM is designed to solve.
Common Signs of a Failing BCM
If you’re noticing any of the following, a faulty BCM is the likely cause. A failing module can often log communication Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or other U-codes, indicating a loss of communication with other modules.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights (headlights, taillights) staying on or not turning on.
- ✔ Erratic behavior from the radio or climate control system.
- ✔ False warnings on the instrument cluster (e.g., ‘Service Airbag,’ ‘Service StabiliTrak’).
- ✔ Remote keyless entry failing to work.
- ✔ The vehicle’s security system preventing it from starting.
A Straightforward Guide to Installation
Installing your new BCM is a manageable job for a confident DIYer. The BCM is typically located on the left-hand (driver’s) side of the dashboard. While this is a plug-and-play part, some vehicles may require a simple relearn procedure after installation.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On the Enclave, the BCM is usually found under the driver’s side of the dashboard, often behind a kick panel. You may need to remove a trim panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely re-attach all electrical connectors. Ensure they click into place.
- Post-Installation Checks: Reconnect the battery terminal. Start the vehicle and test all body functions—lights, windows, locks, etc. In some cases, additional steps may be needed.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system and must be performed with a professional-grade scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light and traction control operation.

Frequently Asked Questions
How does the VIN programming work?
After you place your order, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). Our technicians use this to load the exact software and vehicle-specific settings for your car onto the BCM before it ships. This makes installation much simpler.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module.
Will I need special tools for the installation?
Basic hand tools are all that’s needed for the physical installation. However, if your vehicle displays an airbag light after installation, a professional diagnostic tool will be required to perform the ‘Setup SDM Primary Key’ relearn procedure.
Is this a guaranteed fix for my car’s electrical problems?
This part corrects issues caused by a faulty BCM. While the BCM is a very common point of failure for the symptoms listed, you should always perform proper diagnostics to confirm it’s the root cause. Check for wiring, fuse, and ground issues first.
What happens if I don’t do the Brake Pedal Position Relearn?
If your vehicle requires this procedure and it is not performed, you may experience issues with your brake lights not working correctly or see ‘Service StabiliTrak’ / ‘Traction Control’ warnings on your dash, as the system relies on accurate pedal position data.
