Struggling with erratic door locks or flickering dashboard lights on your 2008-2012 Buick Enclave during a rainy family road trip? You’re not alone—many owners face these frustrating electrical gremlins that can turn a smooth drive into a headache.

Common Issues & How This Fixes Them
In my two decades of automotive diagnostics, I’ve encountered countless 2008-2012 Buick Enclave owners dealing with BCM failures that manifest in subtle yet disruptive ways. One common problem is malfunctioning power accessories—doors that won’t lock remotely or windows that stutter, often triggered by moisture ingress or voltage spikes, leading to DTC U0101 for lost communication. This not only compromises security but can strand you in inconvenient spots, like a busy parking lot. Another frequent issue is erratic lighting behavior, such as headlights dimming unexpectedly or interior lights staying on, draining the battery overnight; causes include corroded connectors or software glitches, exacerbating in cold weather. I’ve seen this escalate to no-start scenarios where the anti-theft system locks out the engine, mimicking fuel pump failures but tracing back to BCM faults.
Replacing with our pre-programmed 20864767 BCM resolves these by restoring precise control signals and updating firmware to prevent recurrence. For instance, in a real shop case, a client’s Enclave had persistent airbag warning lights post-collision; the new module cleared the codes after proper setup, avoiding expensive dealer visits. It also tackles intermittent wiper failures common in rainy conditions, ensuring safety on slick roads. If you’re searching “how to fix Enclave BCM electrical problems,” this part provides a direct path to reliability, often outperforming generic fixes by integrating seamlessly with GM’s network. Always check for related issues like blown fuses first— a quick multimeter test can confirm BCM involvement 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 2008-2012 Enclave.
- Disconnect the battery to ensure safety and prevent electrical surges—locate the BCM on the left-hand dash side.
- Remove the old module by unplugging connectors and unscrewing mounts; compare with the new 20864767 for matching fit.
- Install the new BCM, reconnect all wiring securely, and reconnect the battery.
- Perform post-install procedures: Reset the airbag warning light via the ‘Setup SDM Primary Key in BCM’ using a diagnostic tool; recalibrate the brake pedal if needed for optimal braking.
- For theft deterrent relearn (only if no-start occurs): Cycle the key from off to on 10 times, waiting 10 minutes per cycle if prompted—consult your manual or a technician for variations.
