Is Your GM Truck or SUV Plagued by Bizarre Electrical Issues?
If you’re dealing with flickering lights, a malfunctioning climate control system, power windows with a mind of their own, or a security light that prevents your 2003-2007 Silverado, Sierra, Tahoe, or other GM vehicle from starting, the root cause is likely a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can create a cascade of frustrating and difficult-to-diagnose problems. This VIN-programmed replacement BCM, part number 10383536, is the definitive solution to restore full functionality and reliability to your vehicle.
Symptoms of a Failing GM Body Control Module
- ✔ Unresponsive or erratic power windows, door locks, and interior/exterior lights.
- ✔ HVAC and climate control systems not working correctly, or the blower motor running intermittently.
- ✔ An illuminated airbag warning light, often accompanied by diagnostic trouble code (DTC) B1001.
- ✔ Security system malfunctions, leading to a no-start or crank-no-start condition.
- ✔ Inaccurate or non-functional gauges on the instrument cluster.
- ✔ Communication errors with other vehicle modules when using a diagnostic scanner.
Why Our Programmed Silverado Body Control Module is the Best Solution

We load the latest GM software updates, which can resolve issues that were present even in the original factory module. This is a true plug-and-play fix that restores your vehicle’s electronic systems to their original operating condition.
Installation is straightforward for any DIYer or professional technician. The BCM is typically located under the driver’s side dashboard, near the steering column.

There is no core charge, so you can keep your old part without any hassle.
