Restore Full Electrical Function to Your GM Truck or SUV
Are you battling a frustrating array of electrical problems in your Chevrolet Silverado, GMC Sierra, or Cadillac Escalade? Intermittent wipers, flickering lights, unresponsive power windows, or a persistent airbag light are common signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can create chaos. This genuine quality GM BCM, part number 15263363, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a seamless, plug-and-play installation.
From the Diagnostic Bay
We had a 2009 Sierra 2500 in the shop that was driving the owner crazy. The radio would randomly shut off, the dome light would stay on, and the power locks worked only when they wanted to. He had already replaced the battery and checked fuses with no luck. A quick scan showed communication errors with the BCM. We installed one of our VIN-programmed modules, and in under 10 minutes, every single issue was resolved. These symptoms often seem unrelated, but they almost always point back to a faulty BCM.

Common Symptoms of BCM Failure
- ✔ Unresponsive or erratic power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ HVAC and climate control systems not functioning correctly.
- ✔ Vehicle security system malfunctions or false alarms.
- ✔ Airbag warning light illuminated on the dash (often with DTC B1001).
- ✔ Intermittent stalling, no-start conditions, or communication errors with other modules.
- ✔ Wipers operating randomly or not at all.
Installation and Post-Install Procedures
The BCM is typically located under the driver’s side dashboard, near the steering column. Physical installation is straightforward and usually takes only a few minutes. However, after installation, some vehicles may require additional electronic steps:
- Airbag System Sync: If the airbag light remains on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool and syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure proper brake light and traction control operation.
This module comes with a one-year warranty and requires no core return, allowing you to complete your repair without the hassle of sending back the old part.
Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that manages and controls your vehicle’s non-engine related electronic systems. This includes power windows, locks, lights, wipers, security system, and climate controls.
Is this BCM ready to install out of the box?
Yes. We pre-program the module with your vehicle’s VIN before shipping. This ensures it communicates correctly with your truck or SUV’s other systems for a true plug-and-play installation, with no dealership visit required for programming.
Where is the BCM located on my Silverado or Tahoe?
On most 2007-2013 GM trucks and SUVs, the BCM is located under the driver-side dashboard, to the left of the steering column. It is typically a black box with several large electrical connectors.
My airbag light is on after installing the new BCM. What do I do?
This is a common security measure. You will need a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ function. This procedure syncs the new BCM with the airbag module and will turn off the light.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep or dispose of your original module at your convenience.
