Restore Full Electronic Control to Your GM Truck or SUV
Are you battling frustrating and unpredictable electrical problems in your 1998-2000 GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, a faulty security system, or even a no-start condition can often be traced back to a single point of failure: the Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can create a cascade of confusing symptoms. This replacement BCM, part number 19153625, is the definitive solution to restore your vehicle’s functionality and your peace of mind.
Unlike a generic part from a local store, this module is not just a simple replacement; it’s a fully prepared solution. We program the BCM specifically to your vehicle’s unique Vehicle Identification Number (VIN) before it ships. This critical step ensures compatibility with your vehicle’s specific options and systems, flashing the module with the latest software updates from GM. This eliminates the need for a costly trip to the dealership for programming, saving you significant time and money.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lights (flickering, staying on, or not turning on).
- ✔ The security or anti-theft light staying on, preventing the engine from starting.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Wipers behaving erratically or not parking in the correct position.
- ✔ False warnings on the instrument cluster, such as ‘door ajar’ lights.
- ✔ Rapid battery drain while the vehicle is parked.
Installation and Setup for Your 1998-2000 Blazer S10 BCM
Physical installation of the 1998-2000 Blazer S10 BCM is generally straightforward. Depending on your model, it is typically located behind the center or left-hand side of the dashboard. Once the new, pre-programmed module is installed, you may need to perform one or more electronic relearn procedures to ensure all vehicle systems communicate correctly. While our VIN programming handles the majority of the setup, certain security and safety systems require a final handshake once installed in the vehicle.
Post-Installation Procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade diagnostic tool to sync the new BCM with the existing airbag control module (SDM). This is a critical safety step.
- Brake Pedal Position Relearn: On some models, a recalibration of the brake pedal position sensor may be needed. This ensures your brake lights function correctly and that systems like traction control operate as intended.
Please Note: Specific procedures can vary by exact year and model. We always recommend consulting a factory service manual or a qualified automotive technician for guidance.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the main computer for your vehicle’s comfort and convenience features. It controls functions like power windows, locks, interior and exterior lighting, the anti-theft system, wipers, and various other electronic accessories not related to the engine.
Is this BCM truly plug-and-play?
Our service makes it as close to plug-and-play as possible. We program the module to your VIN, which handles the essential software setup. However, due to vehicle security protocols, you may need to perform additional relearn procedures for systems like the airbags or brakes with a scan tool after installation.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot ship your order until we receive this information, as it is required to program the module correctly for your specific vehicle.
Do I need to send my old BCM back?
No. This part has no core charge. You can keep your original module, which can be helpful for reference or if you ever need to revert to the original part for diagnostic purposes.
What if my airbag light is on after I install the BCM?
An illuminated airbag light is a common occurrence and means the new BCM needs to be electronically synced with your vehicle’s airbag module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a safety-critical step that should be performed by a qualified technician.
