2008 – 2012 Chevrolet EXPRESS 2500 Body Control Module (BCM) 20864767 – Programmed to Your VIN
Imagine you’re hauling cargo in your 2008-2012 Chevrolet Express 2500, and suddenly the door locks fail, interior lights flicker erratically, or the security system triggers false alarms—frustrating issues that halt your workday. These symptoms often point to a faulty Body Control Module (BCM), the central hub managing electrical systems like lighting, locks, and anti-theft features. Our pre-programmed BCM, part number 20864767, arrives flashed with the latest GM updates tailored to your VIN, ensuring seamless integration and restored functionality. It replaces numerous OEM numbers including 10382479, 15093910, and others up to 95151084, fitting a wide range of GM vehicles from Equinox to Yukon models. This isn’t just a swap; it’s a precise match that resolves intermittent failures, drawing from over two decades of diagnostics to prevent recurring problems like those seen in high-mileage vans exposed to moisture or vibration.

Common Issues & How This Fixes Them
Owners of 2008-2012 Chevrolet Express 2500 vans frequently encounter BCM-related troubles that disrupt daily operations. For instance, erratic door locks or non-functional power accessories often stem from internal circuit failures due to age or corrosion, leading to DTCs like U0140 (lost communication with BCM) or B1370 (device ignition off draw). In one scenario, a delivery driver noticed the headlights staying on after shutdown, draining the battery overnight— a classic sign of BCM relay issues exacerbated by vibration from rough roads. Replacing with our programmed 20864767 unit fixes this by restoring proper signal processing, preventing power drain and ensuring accessories respond correctly. Another common problem: intermittent no-start conditions tied to the anti-theft system, where the BCM fails to recognize the key, throwing codes like B2960. This module, updated via your VIN, recalibrates the system to match factory specs, resolving these without extensive rewiring. We’ve seen cases where moisture from leaky seals causes short circuits, mimicking fuel pump failures but actually BCM-driven; our solution includes enhanced programming to mitigate such environmental factors. By addressing root causes like voltage spikes from alternator problems, this BCM not only clears codes but also extends the lifespan of connected components, offering peace of mind for long-haul drivers. Remember, if symptoms include dashboard warning lights, scan for body codes first—simple OBD-II checks can confirm BCM involvement before deeper troubleshooting.
Easy Installation Guide
- Provide your VIN after purchase so we can program the BCM with the latest GM updates before shipping.
- Disconnect the battery to ensure safety and prevent electrical surges during the swap.
- Locate the BCM in the center dash area of your Express 2500; remove any panels or brackets securing it.
- Unplug the old module, connect the new one, and secure it in place—match connectors carefully to avoid pin damage.
- Reconnect the battery and perform a theft deterrent relearn if a no-start occurs: Insert key, turn to ON for 10 minutes, off for 5 seconds, repeat three times until the security light extinguishes.
- Test all functions like lights, locks, and wipers; clear any stored codes with a scan tool for optimal performance.
