2008 – 2012 Chevrolet EXPRESS 3500 Body Control Module (BCM) 15921352 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with your 2008-2012 Chevrolet Express 3500 van refusing to start on a busy delivery day, or the interior lights flickering erratically during a long haul? These frustrations often trace back to a faulty Body Control Module, disrupting everything from power locks to alarm systems. As a seasoned mechanic who’s swapped dozens of BCMs in GM vans, I’ve seen how a failing unit can throw DTC codes like U0140 or B1370, leaving you stranded. Our pre-programmed BCM, specifically the 15921352, resolves this by arriving flashed with the latest GM updates tailored to your VIN.

Common Issues & How This Fixes Them
In my years diagnosing GM vehicles, I’ve encountered Express 3500 owners puzzled by symptoms like intermittent door locks that fail mid-shift or dashboard warnings that won’t reset. A common culprit? The BCM degrading from moisture exposure or electrical surges, common in work vans facing rough weather. This leads to issues such as erratic wiper operation, which I’ve fixed by replacing the module to restore signal integrity. Another frequent headache is security system malfunctions causing no-crank conditions—think of that time a client couldn’t start their van after a battery swap, only to find corrupted BCM data was the root. Our pre-programmed unit addresses this by integrating fresh GM firmware, effectively clearing codes and recalibrating systems. For towing enthusiasts, a faulty BCM might trigger false ABS alerts, compromising safety; this replacement stabilizes those circuits, drawing from real cases where it prevented breakdowns on highways. Plus, it tackles power window glitches in older models, ensuring smooth operation without the need for extensive rewiring. By opting for this BCM, you’re not just fixing symptoms—you’re proactively enhancing vehicle longevity, especially in high-mileage scenarios where electrical reliability is key.
Easy Installation Guide
- Provide your VIN immediately after purchase so we can program the BCM with the latest GM updates before shipping.
- Disconnect the battery to ensure safety, then locate the BCM in the center dash area of your Express 3500.
- Remove the old module by unplugging connectors and unbolting it carefully, noting any specific mounting for your van model.
- Install the new BCM, reconnect all wiring securely, and reconnect the battery.
- Perform necessary relearns: If a no-start occurs, conduct theft deterrent relearn by cycling the key from off to run (without cranking) for 10 minutes, three times. Also, reset the airbag warning light via the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool.
- For some vehicles, recalibrate the brake pedal to optimize braking performance—consult your manual or a technician for precise steps.
