Restore Full Electrical Function to Your GM Truck or SUV
Is your Silverado, Sierra, S10, or Blazer suffering from bizarre electrical issues? The Body Control Module (BCM) is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and unpredictable problems. This replacement BCM, part number 19153625, is the definitive solution to restore your vehicle’s factory functions. We eliminate the guesswork and costly dealership visits by pre-programming this module specifically to your vehicle’s VIN before it ships. This ensures a seamless installation and proper communication with your vehicle’s other electronic systems.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on, not turning on, or flickering.
- ✔ The security or anti-theft system (Passlock/VATS) acting up, causing no-start conditions.
- ✔ Erratic behavior from the radio or instrument cluster gauges.
- ✔ False warnings on the driver information center.
- ✔ Horn honking randomly or not working at all.
- ✔ Wipers operating incorrectly or not parking in the correct position.

Installation and Post-Install Notes
While this module is designed for a direct-fit installation, some vehicles may require additional calibration steps after the part is installed. Please be aware of the following potential procedures:
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This indicates a sync mismatch between the new BCM and the airbag’s SDM module. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor might be necessary to ensure correct brake light operation and to satisfy the traction control system.
We always recommend consulting a factory service manual or a qualified technician for vehicle-specific instructions.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the main computer for your vehicle’s non-engine related electronics. It controls functions like power windows, door locks, interior and exterior lighting, the security system, wipers, and the horn.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and calibrations for your specific vehicle’s make, model, and options. This ensures it works correctly right out of the box and avoids compatibility issues.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
Is this a difficult part to replace?
The physical replacement is typically straightforward, involving removing a few dash panels and connectors. The BCM is often located under the driver’s or center dash area. The main challenge is typically the programming, which we handle for you before shipping.
What if the airbag light is on after I install the new BCM?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to the airbag system. A technician with a high-level diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
