2008 – 2012 GMC Savana 1500 Body Control Module (BCM) 20864767 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Think back to that frustrating moment when your 2008-2012 GMC Savana 1500 suddenly refuses to unlock the doors, or the interior lights stay on no matter what, draining your battery overnight. You’re left wondering, “Why is my Savana 1500 BCM causing random electrical failures?” As a seasoned mechanic who’s fixed countless vans like yours, I’ve seen how a faulty body control module can turn a reliable workhorse into a headache, especially on those long hauls or during harsh winter conditions where moisture creeps in and corrupts the system. This pre-programmed BCM, part number 20864767, directly addresses those glitches by restoring seamless control over lights, locks, and security features. It fits a wide range of GM vehicles, including Equinox 07-09, Express vans from 08-12, Tahoe 10 models with ID 25892622, and more—cross-compatible with numbers like 10382479, 15093910, up to 95151084. What sets this apart is the VIN-specific flashing with the latest GM updates, ensuring it clears persistent DTC codes and boosts overall electrical reliability without the guesswork.

Common Issues & How This Fixes Them
In my years diagnosing GM vans, the BCM in 2008-2012 Savana 1500 models often fails due to corrosion from exposure to elements, leading to symptoms like erratic door locks that won’t respond to your key fob—imagine arriving at a job site unable to secure your tools. Another common headache is dashboard warning lights flashing DTC codes such as U0140 or B1370, signaling lost communication with other modules, which can disable features like remote start. Over time, voltage spikes from aging wiring exacerbate this, causing intermittent power to headlights or wipers, a real safety risk during rainy drives. This replacement BCM fixes these by providing a fresh, updated unit that reestablishes stable connections, effectively clearing those trouble codes and restoring normal operation. For instance, I’ve helped owners who thought their van’s theft system was the culprit; swapping in a programmed BCM resolved the immobilizer glitches without needing full system resets. It also tackles battery drain from malfunctioning courtesy lights, ensuring your Savana stays ready for demanding tasks like towing trailers. By addressing root causes like software glitches, this part prevents recurring failures, offering long-term reliability that goes beyond a quick patch—think improved performance in extreme weather, where older modules falter.
Easy Installation Guide
- Provide your VIN after purchase so we can flash the BCM with the latest GM updates tailored to your 2008-2012 Savana 1500.
- Disconnect the battery to ensure safety and prevent electrical surges during the swap—locate the BCM in the center dash area.
- Remove the old module by unplugging connectors and unscrewing mounts; compare it to the new one for a perfect fit.
- Install the new BCM securely, reconnect all wiring, and double-check for loose connections that could trigger faults.
- Reconnect the battery and perform any necessary relearns: If a no-start occurs, cycle the key from off to on (without cranking) 3-5 times to relearn the theft system per GM standards.
- Test all functions like lights, locks, and security to confirm everything operates smoothly.
