Is Your GM Truck Plagued by Electrical Gremlins?
n
If you’re dealing with bizarre and frustrating electrical problems in your 2003-2006 Chevrolet Avalanche, Silverado, or another compatible GM truck or SUV, a failing Body Control Module (BCM) is the likely culprit. The BCM is the central command center for your vehicle’s body electronics, managing everything from your power windows and door locks to the HVAC system and security features. When it starts to fail, it can create a cascade of issues that are difficult to diagnose and can even prevent your vehicle from starting.

From the Diagnostic Bay
n
We once had a 2005 Silverado in the shop where the owner had spent hundreds chasing what he thought was a grounding issue. The radio would cut out, the dome light would flicker, and the power locks worked intermittently. After checking all the main grounds, we suspected the BCM. Instead of a lengthy diagnostic and programming process, we installed one of our VIN-programmed 15116066 modules. In under 15 minutes, every single electrical issue was resolved. It’s a perfect example of how this part can save you hours of frustration and diagnostic fees.

Installation is straightforward. The BCM is typically located under the driver’s side dashboard, near the steering column. Disconnecting the battery before swapping the module is recommended. While most installations are seamless, some vehicles may require additional steps:

- Airbag System Sync: If the airbag light remains on after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool.
