Restore Full Electronic Functionality to Your GM Truck
Is your 1999-2000 GMC Sierra 2500 or other compatible GM vehicle suffering from bizarre electrical issues? Flickering lights, malfunctioning power windows and locks, or a security system that acts on its own are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your truck’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 systems to perfect working order.
Unlike a generic part from a local store, this BCM is delivered to you fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We install the latest GM software updates, ensuring optimal performance and compatibility right out of the box. This plug-and-play approach eliminates the need for expensive dealership programming, saving you both time and money. Simply provide your VIN after purchase, and we handle the complex flashing process before shipping the part directly to you.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ The security system or horn activating randomly.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ Problems with the radio or climate control systems.
- ✔ A “Service Vehicle Soon” or other warning lights on the dash.
- ✔ Key fobs that stop working or have an inconsistent range.

From the Diagnostic Bay
We had a 2000 Silverado 1500 come in that was driving the owner crazy. The dome light would randomly turn on while driving at night, the driver’s side window would only work occasionally, and the horn would blare for a few seconds every time he’d hit a bump. He had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we saw multiple communication error codes all pointing back to the BCM. We installed one of our pre-programmed modules, and it was like the truck was brand new again. Every function worked perfectly on the first try. It’s a classic case of how a single failing module can create a host of seemingly unrelated electronic gremlins.
Installation and Post-Install Procedures
Installation is straightforward for those with mechanical experience. The BCM is typically located under the driver’s side of the dashboard. After disconnecting the battery and removing the old module, this pre-programmed unit plugs directly into the existing wiring harnesses. However, on some vehicles, additional steps may be required to sync the new module with other vehicle systems.
- Airbag System Sync: If the airbag warning light illuminates after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light operation and to prevent issues with the traction control system.
We always recommend consulting a factory service manual or a qualified technician for vehicle-specific instructions and procedures.

Frequently Asked Questions
Do I need to send you my old BCM?
No, there is no core charge for this part. You can keep your original module.
What information do you need to program the module?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. This allows us to program the BCM with the correct software and settings for your specific truck.
Is this a simple plug-and-play installation?
For most functions, yes. Because it comes pre-programmed, it will control the main body functions immediately. However, as noted, some vehicles may require an additional relearn procedure for the airbag or brake systems, which requires a professional scan tool.
Will this fix my specific electrical problem?
This module will correct issues directly caused by a faulty BCM. If your vehicle exhibits several of the symptoms listed, such as erratic lights, locks, and security system behavior, a failing BCM is the most likely cause. We always recommend proper vehicle diagnosis before ordering.
Where is the BCM located on my 1999 Sierra 2500?
On the 1999-2000 Sierra and Silverado models, the Body Control Module is typically located on the driver’s side, up under the dashboard to the left of the steering column.
