2008 – 2012 Buick Enclave Body Control Module (BCM) 20864768 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with your 2008-2012 Buick Enclave refusing to start on a chilly morning, or the lights flickering erratically during a family road trip? These frustrating electrical glitches often stem from a failing Body Control Module, leaving you stranded and questioning, “Why won’t my Enclave’s power windows or door locks respond?” As a seasoned automotive advisor who’s diagnosed countless GM vehicles, I’ve seen how a compromised BCM disrupts everything from interior lighting to security systems, especially in crossover SUVs like the Enclave exposed to harsh weather. The good news? Our pre-programmed BCM, part number 20864768, resolves these issues swiftly. It’s flashed with the latest GM updates using your VIN for seamless compatibility, clearing persistent DTC codes and restoring smooth operation.

Common Issues & How This Fixes Them
In my two decades fixing GM vehicles, BCM failures in the 2008-2012 Buick Enclave often manifest as intermittent no-start conditions, where the engine cranks but won’t fire—usually due to corrupted theft deterrent signals. Another frequent headache is erratic interior functions, like doors not locking or windows failing mid-roll, caused by moisture ingress or voltage spikes degrading the module over time. I’ve encountered owners puzzled by dashboard warning lights that won’t clear, such as airbag alerts triggered by BCM communication errors, disrupting daily drives. Then there’s the random power loss to accessories, impacting everything from headlights to climate control, especially in humid environments where corrosion accelerates wear. Replacing with our pre-programmed BCM addresses these root causes by restoring precise control signals, effectively clearing DTC codes like P0601 or U0140 that plague these systems. For instance, a client with a 2010 Enclave towing a trailer reported improved stability after swap-out, as the new module ensured consistent voltage to brakes and lights. This not only fixes symptoms but prevents cascading failures, like battery drain from faulty relays, saving you from costly tow bills. Expert tip: Scan for codes before replacement to confirm BCM involvement, avoiding misdiagnosis with similar issues like bad grounds.
Easy Installation Guide
- Provide your VIN 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 shorts during the swap—locate the BCM on the left-hand dash side.
- Remove the old module by unplugging connectors and unscrewing mounts; compare part numbers to verify compatibility.
- Install the new BCM, reconnecting all harnesses securely to avoid loose connections that could trigger new codes.
- Reconnect the battery and perform any necessary relearns: If a no-start occurs post-install, initiate theft relearn by inserting the key, turning to ON for 10 minutes (three cycles if needed), then starting the engine.
- Test all systems, including lights, locks, and accessories, to confirm functionality.
