2006 – 2011 Buick Lucerne Body Control Module (BCM) 15880684 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Imagine cruising through a rainy evening in your 2006-2011 Buick Lucerne, only for the wipers to stutter unpredictably, doors refusing to lock, or dashboard lights flickering like a bad horror movie. These frustrating electrical glitches often point to a failing Body Control Module (BCM), the brain behind your vehicle’s comfort and safety systems. If you’re asking, “Why does my Lucerne have intermittent power window issues or random DTC codes popping up?” you’re likely dealing with BCM wear from years of exposure to heat, moisture, or voltage spikes. Our pre-programmed BCM, part number 15880684, arrives ready to install, flashed with the latest GM updates using your VIN for a perfect match. This eliminates guesswork and restores seamless operation, from headlights to security features. Drawing from over two decades in auto diagnostics, I’ve seen how a fresh BCM not only clears persistent trouble codes but also enhances overall electrical stability, preventing breakdowns during long drives or heavy loads. It’s compatible with numerous GM models, ensuring broad reliability without the hassle of core returns.

Common Issues & How This Fixes Them
In my years fixing GM vehicles, BCM failures in 2006-2011 Buick Lucerne models often manifest as erratic behaviors that disrupt your drive. For instance, you might notice power locks failing intermittently, especially in humid conditions, caused by corroded internal circuits that degrade over time. This can lead to security vulnerabilities or even stranded situations if the anti-theft system malfunctions. Another frequent headache: dashboard warning lights staying on, triggering codes like P1629 or U0140, stemming from faulty communication between the BCM and other modules. I’ve diagnosed cases where owners ignored these, only to face escalating problems like non-functional windows during a storm. Replacing with our VIN-programmed BCM resolves this by recalibrating the network, clearing those DTCs, and restoring smooth integration. Consider a real scenario—a client with a 2008 Lucerne towing a trailer experienced flickering headlights and reduced towing reliability due to voltage inconsistencies. Post-replacement, the module stabilized power distribution, enhancing performance under load. Additionally, if your Lucerne’s interior lights dim randomly or the remote keyless entry quits, it’s often BCM-related wear from electrical surges. This fix not only addresses root causes but prevents future issues, like improving fuel efficiency through better accessory management. Always scan for codes first; a quick OBD-II check can confirm if the BCM is the culprit before diving in.
Easy Installation Guide
- Provide your VIN immediately after purchase so we can program the BCM with the latest GM updates tailored to your 2006-2011 Buick Lucerne.
- Disconnect the battery to ensure safety and prevent electrical shorts during the swap—locate the BCM on the right side of the dash.
- Remove the old module by unplugging connectors and mounting screws; compare it to the new one for a match.
- Install the new BCM securely, reconnect all wiring, and reattach the battery.
- Perform any necessary relearns: If a no-start occurs due to theft system, cycle the key from off to on (without starting) for 10 minutes, three times. For airbag light reset, use a diagnostic tool for the ‘Setup SDM Primary Key in BCM’ procedure.
- Recalibrate the brake pedal if needed for optimal braking—consult your manual or a tech, as some vehicles require this post-install for safety.
