Fix Annoying Electrical Problems in Your GM Truck or SUV
Are you dealing with baffling electrical issues in your Chevrolet Suburban, Tahoe, Silverado, or GMC Sierra? Flickering lights, unresponsive power windows, a malfunctioning HVAC system, or random warning lights on the dash are all classic signs of 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 cause a wide range of frustrating problems. This genuine OEM-quality module, part number 15263363 (and its compatible interchange 25844480), is the reliable, pre-programmed solution to restore your vehicle’s full functionality.
Is Your Vehicle Showing These Symptoms of BCM Failure?
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights behaving erratically (staying on, not turning on, or flickering).
- ✔ HVAC and climate control functions are unresponsive or the blower motor is acting up.
- ✔ The security system is malfunctioning, causing no-start or stalling conditions.
- ✔ An airbag warning light is illuminated on the dash, often with DTC B1001.
- ✔ Multiple, seemingly unrelated diagnostic trouble codes are present.

Installation and Post-Install Considerations
Installation is simple for the average DIYer. The BCM is typically located under the driver’s side dashboard, near the steering column. The physical swap takes only a few minutes. However, please be aware of potential post-installation procedures:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is required to perform the “Setup SDM Primary Key in BCM” function. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.

Frequently Asked Questions
Is this BCM really plug-and-play?
Yes! We program the module to your vehicle’s VIN before shipping. This means it will communicate with your vehicle’s existing systems without requiring a trip to the dealership for additional programming, saving you time and money.
Where is the BCM located on my 2008 Suburban 1500?
The Body Control Module is located under the driver’s side dashboard, typically to the left of the steering column. It is a black box with several large electrical connectors.
What if my airbag light is on after I install the new BCM?
