2006 – 2013 Chevrolet Impala Body Control Module (BCM) 25934762 – Programmed to Your VIN
Imagine dealing with erratic dashboard lights or doors that won’t lock properly on your 2006-2013 Chevrolet Impala during a rainy commute—frustrating, right? These symptoms often point to a failing Body Control Module (BCM), the central hub managing your vehicle’s electrical systems. Our pre-programmed BCM, part number 25934762, arrives flashed with the latest GM updates using your VIN for a perfect match. It replaces a wide range of OEM numbers like 10382479, 15093910, and others, ensuring compatibility across various GM models. This isn’t just a swap; it’s a reliable solution that restores smooth operation, preventing minor glitches from escalating into major breakdowns. Drawing from years in the shop, I’ve seen how a fresh BCM can transform intermittent issues into dependable performance, especially in high-mileage Impalas prone to moisture-related failures.

Common Issues & How This Fixes Them
Owners of 2006-2013 Chevrolet Impalas frequently report problems like flickering interior lights, unresponsive power windows, or erratic wiper behavior—often tied to a corroded or outdated BCM. In my experience, these stem from water intrusion near the left dash area, where the module sits, leading to short circuits and diagnostic trouble codes (DTCs) such as U0140 for lost communication or B1325 for battery voltage irregularities. Another scenario: during winter drives, you might notice the security system falsely activating, stranding you with a no-start condition. Replacing with our programmed BCM resolves this by recalibrating the network, ensuring all modules communicate properly. For instance, if you’re troubleshooting “how to fix intermittent door lock failures on Impala,” this unit often clears the issue without needing additional relays. Expert tip: Before full replacement, check fuses and grounds—I’ve fixed many by cleaning connections first, but when the BCM is the culprit, a fresh install with updated firmware prevents comebacks. This approach not only fixes the immediate fault but also improves system resilience against future electrical gremlins.
Easy Installation Guide
- Provide your VIN after purchase so we can program the BCM with the latest GM updates for your specific Impala.
- Disconnect the battery to ensure safety and reset any residual codes—wait at least 10 minutes.
- Locate the BCM on the left-hand dash (LH dash) behind the panel; remove retaining clips and unplug connectors carefully.
- Install the new BCM by reconnecting harnesses securely, then reassemble the dash components.
- Reconnect the battery and perform a key cycle: Turn the ignition on for 10 seconds, off for 5, repeat three times to initialize.
- If a no-start occurs post-install due to theft deterrent, conduct the relearn—insert key, turn to ON for 10 minutes until the security light goes off, then start the engine. No special tools needed per GM standards.
