Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your truck? Flickering lights, a non-responsive HVAC system, or power windows with a mind of their own are common signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features. When it fails, it can cause a cascade of confusing issues. This genuine quality GM Body Control Module, interchangeable with part number 25835966, is the definitive solution for your 2007-2013 GM vehicle, arriving pre-programmed to your specific VIN for a true plug-and-play repair.
From the Diagnostic Bay
We had a 2011 Silverado 2500 in the shop that was driving its owner crazy. The radio would turn off randomly, the dome lights wouldn’t work, and the security light was always on, sometimes preventing the truck from starting. The owner had already replaced the battery and checked fuses to no avail. After hooking up our scanner, we saw a slew of communication error codes pointing to the BCM. Instead of a costly trip to the dealership for a new module and programming, we installed one of our pre-programmed units. In under 10 minutes, all the strange electrical issues were gone. It’s a common failure point, but with a properly programmed module, it’s a straightforward fix.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or failing to turn on.
- ✔ HVAC and climate control functions not working correctly.
- ✔ Vehicle security system malfunctioning, causing no-start conditions.
- ✔ The airbag warning light is illuminated, often with DTC B1001.
- ✔ Unexplained battery drain while the vehicle is off.
- ✔ Wipers behaving erratically or not parking in the correct position.
The Superior Solution: A Pre-Programmed 2013 Sierra BCM
Don’t settle for a trip to the dealership that involves high labor costs and vehicle downtime. Our service provides you with a BCM that is professionally programmed with the latest GM software updates using your vehicle’s VIN. This critical step ensures that the module communicates perfectly with all other systems in your truck right out of the box. This isn’t just a replacement part; it’s a complete, ready-to-install solution that restores your vehicle to its original factory specifications and performance.
Installation is simple for any DIYer or professional mechanic. The BCM is typically located under the driver’s side dashboard near the steering column. Once the old module is swapped out, most functions are immediately restored. For specific situations, such as a persistent airbag light, a post-installation procedure may be needed. Using a professional scan tool, a technician can perform the ‘Setup SDM Primary Key in BCM’ function to sync the systems. This is a testament to the complexity of modern vehicles, but our programmed 2013 Sierra BCM makes the hardware part of the job as easy as possible.
