Tired of Chasing Electrical Gremlins in Your SUV?
Is your Envoy, Trailblazer, or Rainier acting possessed? Flickering lights, power windows with a mind of their own, a dead instrument cluster, or a frustrating no-start condition can all point to one culprit: a failing Body Control Module (BCM). The BCM is the central command for your vehicle’s body electronics, and when it fails, it can cause a cascade of bizarre and unpredictable issues. Stop throwing parts at the problem and get the definitive solution with our pre-programmed BCM, designed to get your truck back on the road quickly and reliably.
Common Symptoms of a Failing BCM & Your Direct-Fit Solution

- Interior or exterior lights staying on or not turning on at all
- Instrument cluster gauges behaving erratically or going dark

Expert Insight: The Critical Role of VIN Programming
As a veteran technician, I can’t stress this enough: a BCM for these GM trucks is not a simple ‘one-size-fits-all’ part. It’s the traffic controller for dozens of electronic functions, from your power seats to your anti-lock brakes. Each vehicle’s specific options (like security systems, sunroofs, etc.) are coded into the BCM via the VIN. Installing a non-programmed module from a salvage yard is a recipe for disasterโyou’ll likely have more problems than you started with. Our VIN programming service isn’t just a convenience; it’s a critical step that ensures every component in your vehicle works together exactly as the factory intended.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, simply reply to your order confirmation email with your 17-digit VIN, or add it to the ‘notes’ section during checkout. We cannot ship your order until we receive the VIN to program the module.
Is this BCM truly ‘plug-and-play’?
Yes, for the vast majority of functions. Because it is programmed to your VIN, your vehicle will start and run, and the core electronic features will work immediately. However, as with any BCM replacement, certain security or safety systems may require a simple ‘relearn’ procedure. We provide clear instructions for potential post-install steps like the Airbag System Sync or Brake Pedal Position Relearn if they are needed.
My original part number is 15787809. Will this part work?
Absolutely. This BCM is a fully compatible replacement for several part numbers, including 15787809, 25802312, and 15135466. We ensure the module we send has the correct hardware and is programmed to function identically to your original.
What tools are needed for the post-installation procedures?
The Brake Pedal Position Relearn can often be done without special tools. However, if the airbag light comes on, the ‘Setup SDM Primary Key in BCM’ procedure requires a professional-grade bidirectional scan tool. Most local repair shops have this equipment if you are unable to perform the procedure yourself.
Do I need to return my old BCM?
No. We do not require you to return your original part. This purchase has no core charge, which saves you the time and expense of a return shipment.
