Stop Chasing Electrical Gremlins in Your GM Truck
Is your Silverado, Sierra, or Tahoe acting possessed? Flickering lights, a dead HVAC system, or power locks with a mind of their own are more than just an annoyance—they’re a sign that your vehicle’s central command center, the Body Control Module (BCM), is failing. Instead of spending a fortune on dealership diagnostics and programming fees, get back in control with this pre-programmed, OEM-quality BCM.

A Mechanic’s Insight: From over 20 years in the garage, I can tell you that BCM failures often get misdiagnosed. Before you replace the module, take 5 minutes to check the main ground connections under the dash and on the frame. A poor ground can cause the same bizarre symptoms and can even damage a new module. A solid ground is the foundation of a healthy electrical system. Installing this 2013 Silverado 3500 Body Control Module 22860591 on a clean, tight ground ensures a permanent fix.
Frequently Asked Questions
What does “VIN Programmed” actually mean for me?
It means we load your vehicle’s unique Vehicle Identification Number (VIN) and all related factory settings into the module before we ship it. This makes the BCM a direct plug-and-play part, allowing it to communicate correctly with your truck’s other computers (like the ECU and TCM) right out of the box, with no extra steps or dealer visits required.
Where is the BCM located on my truck?
On most 2007-2013 GM trucks and SUVs like the Silverado, Sierra, and Tahoe, the Body Control Module is located under the driver’s side of the dashboard, usually to the left of the steering column. Installation typically takes only a few minutes with basic hand tools.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your old module, which saves you the time and hassle of packaging and shipping it back.
Will this fix my airbag light with code B1001?
Yes, a faulty BCM is a common cause of the B1001 code. However, after installing the new module, some vehicles may require an “SDM Key Update” or “Setup SDM Primary Key in BCM” procedure using a professional-grade scan tool to sync the new BCM with the airbag system and clear the light.
