Restore Your Buick’s Electrical System with a Plug-and-Play Solution
Are you dealing with bizarre electrical issues in your 2013-2017 Buick Enclave? Flickering lights, power windows with a mind of their own, or a security system that randomly goes off are classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and unpredictable problems. This isn’t just an annoyance; it can affect vehicle security and safety systems. This replacement BCM is the reliable, straightforward fix you need to get your Enclave back to normal.
I remember a 2015 Enclave that came into my shop with a laundry list of complaints from the owner. The radio would turn off, the interior lights would pulse, and sometimes the car just wouldn’t start. There were no consistent trouble codes, just a lot of communication errors (U-codes). After ruling out battery and alternator issues, we traced the problem to the BCM. It was intermittently failing, corrupting the data network. Replacing it with a pre-programmed unit like this one solved every single issue instantly. It’s a common failure, but thankfully, it’s a very manageable fix with the right part.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your BCM needs attention:
- âś” Erratic or non-functional power windows, door locks, and mirrors.
- âś” Interior or exterior lights that flicker, stay on, or won’t turn on at all.
- âś” The anti-theft or security system engaging incorrectly.
- âś” Dashboard warning lights appearing for no reason (e.g., ABS, Airbag).
- âś” Intermittent no-start conditions where the engine cranks but won’t fire up.
- âś” Communication-related Diagnostic Trouble Codes (DTCs), often in the U-series (e.g., U0140, U0155).

Your Straightforward BCM Installation Guide
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.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system to fully discharge.
- Access the BCM: You will likely need to remove the lower dash panel beneath the steering wheel to gain access to the module.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect and Test: Reinstall any trim panels you removed. Reconnect the negative battery terminal. Start the vehicle and test all body functions—windows, locks, lights, etc.
Important Post-Installation Steps
While this module is programmed for your vehicle, some systems may require a quick recalibration after installation. Please be aware of the following:
- Airbag System Sync: If the 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. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light operation and traction control functionality.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
Do I need to program this BCM?
No. We handle all the programming for you before shipment. Just provide your VIN at checkout, and the module will arrive ready to install.
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer that acts as the brain for your vehicle’s electronic accessories, such as power windows, locks, lights, wipers, and the security system.
Where is the BCM located on my 2013-2017 Enclave?
On the Buick Enclave and its sister vehicles (Traverse, Acadia), the BCM is typically found behind the lower dash panel on the driver’s side, near the steering column.
What if my airbag light is on after installation?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag module. A mechanic with a professional diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old BCM back to us, which saves you time and return shipping costs.
