Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your truck? Flickering lights, a dead HVAC system, or power windows with a mind of their own are common signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics. When it fails, it can cause a cascade of confusing and seemingly unrelated issues. This OEM-quality replacement BCM, part number 22860591, is the definitive solution for your 2007-2011 Chevrolet Silverado 3500 and a wide range of other GM vehicles. It arrives pre-programmed to your specific Vehicle Identification Number (VIN), ensuring a seamless, plug-and-play installation without requiring a costly trip to the dealership for programming.
Common Symptoms of a Failing BCM
- ✔ Unresponsive or erratic power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ Malfunctioning HVAC controls or an inoperative blower motor.
- ✔ An illuminated airbag warning light, often with DTC B1001.
- ✔ Vehicle security system issues, including no-start or stalling conditions.
- ✔ A variety of seemingly random diagnostic trouble codes (DTCs) related to body systems.

Installation & Post-Install Notes
While the physical swap is simple, be aware of potential post-installation procedures.

Best of all, there is no core charge on this part, so you can keep your old module without hassle.

Frequently Asked Questions
What does a Body Control Module do on a Silverado 3500?
The BCM is a computer that manages and controls your truck’s non-engine related electronic functions. This includes the power windows, door locks, interior and exterior lighting, security system, wipers, and HVAC climate controls.
Is this BCM difficult to install?
No, the physical installation is typically very easy. The module is usually located under the driver’s side dashboard and held in place by a few clips or bolts. The entire swap can often be done in under 15 minutes with basic tools.
Will I need to take my truck to the dealership after installing this?
No. Because we pre-program the module to your vehicle’s VIN, you can skip the dealership visit and the associated programming fees. It’s designed for a plug-and-play experience.
My airbag light is on after installation. What should I do?
This is a known possibility. You will need to have a qualified technician use a professional-grade scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system and will turn off the light.
How do I know if this part number (22860591) is correct for my vehicle?
The best way is to match the part number from your original module. This part interchanges with many numbers, including 25844480. You can also use our website’s fitment checker or contact our expert support with your VIN to confirm compatibility.
What is a ‘core charge’ and why don’t you have one?
A core charge is a deposit you pay until you return your old, failed part. We make it simple by not requiring a core charge. You can keep or dispose of your old module without any extra steps or fees.
