Restore Your Enclave’s Electrical System with a Plug-and-Play BCM

If your 2008-2012 Buick Enclave is suffering from bizarre electrical issues like flickering lights, malfunctioning power windows, or random warning messages, a failing Body Control Module (BCM) is often the culprit. As the central nervous system for your vehicle’s comfort and convenience features, a faulty BCM can make driving a frustrating and unpredictable experience. This replacement Body Control Module, part number 15837419, is the reliable, straightforward solution to get your vehicle back to factory-spec performance without a costly trip to the dealership.

Is Your Enclave Showing These Symptoms?

A failing BCM can manifest in numerous ways. Over my 20+ years in diagnostics, these are the most common signs I’ve seen associated with a failing 2008-2012 Enclave BCM. If you’re experiencing any of these, it’s time to consider a replacement.

• ✔ Erratic or non-functional interior and exterior lights.
• ✔ Power windows, locks, or mirrors operating intermittently or not at all.
• ✔ The security system acting up or preventing the vehicle from starting.
• ✔ False warnings on the dashboard (e.g., “Service StabiliTrak,” “Service Airbag”).
• ✔ Communication loss Diagnostic Trouble Codes (DTCs), such as U0140, U0155, or U0100.
• ✔ Unresponsive key fob or remote start functions.
• ✔ Rapid battery drain while the vehicle is parked.

A Straightforward Guide to Your BCM Installation

Replacing the BCM in your Enclave is a manageable job for a confident DIYer. Our pre-programming service eliminates the most difficult step, saving you time and money. Here’s a general guide to get you started:

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
2. Locate the BCM: On the 2008-2012 Enclave, the BCM is typically located on the left-hand (driver’s) side of the dashboard, often behind the lower dash panel near the steering column.
3. Access the Module: You will likely need to remove a few plastic trim panels to gain clear access to the BCM. Take your time and use a trim removal tool to avoid breaking any clips.
4. Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, remove any bolts or screws holding the module in place and take it out.
5. Install the New BCM: Mount your new, pre-programmed BCM in the same location and secure it. Reconnect all electrical connectors, ensuring they click firmly into place.
6. Post-Installation Checks: Reconnect the battery terminal. Start the vehicle and test all body functions: lights, windows, locks, radio, etc. Note that some additional procedures, like an airbag system sync or brake pedal position relearn, may be required if specific warning lights appear.

Frequently Asked Questions

Why do you need my VIN number?

We require your Vehicle Identification Number (VIN) to program the BCM with the latest GM software specific to your Enclave’s exact configuration. This ensures all features work correctly right out of the box, just like a new part from the dealer.

Is this a simple plug-and-play installation?

Yes, for the most part. Because we pre-program the module, you will not need a special scan tool for the initial programming. You simply install the part. However, as noted above, some vehicles may require minor relearn procedures for systems like the airbags or brake sensor if a warning light appears.

Do I need to send my old BCM back?

No, there is no core charge for this part. You can keep your original module, which can be helpful for double-checking part numbers or for any diagnostic comparisons.

Will this fix my “Service StabiliTrak” message?

It can, but it’s not guaranteed. The StabiliTrak system relies on inputs from many sensors. While a faulty BCM can cause this message by disrupting communication, the issue could also be a wheel speed sensor or steering angle sensor. Proper diagnosis is key, but if you have other BCM-related symptoms, this is a likely solution.
