Restore Full Functionality to Your GM Truck’s Electronics
Are you battling frustrating electrical gremlins in your 1999-2000 Silverado, Sierra, or other compatible GM truck? A failing Body Control Module (BCM) is often the culprit behind a host of baffling issues, from flickering lights and malfunctioning power accessories to intermittent no-start conditions. This replacement BCM is the definitive solution, arriving at your door fully programmed to your vehicle’s specific VIN with the latest GM software updates. Eliminate the guesswork and the expensive trip to the dealership for programming.
Common Symptoms of a Failing BCM
The BCM is the central command center for your truck’s body electronics. When it begins to fail, it can cause a wide range of symptoms that may seem unrelated. If you’re experiencing any of the following, a faulty BCM is the likely cause:
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights (headlights, dome lights, dash lights) flickering, staying on, or not turning on.
- ✔ The security or anti-theft system light is on, preventing the engine from starting.
- ✔ The horn sounds randomly or doesn’t work when pressed.
- ✔ Instrument cluster gauges behaving erratically or displaying incorrect information.
- ✔ A persistent dead battery caused by a parasitic electrical draw.
- ✔ Remote keyless entry system is unresponsive.

Our technicians will then flash this BCM with the correct software and vehicle-specific calibration provided by GM. This ensures that when the part arrives, it’s ready for installation, communicating correctly with your truck’s other modules right out of the box. Plus, with our no-core-charge policy, you can keep your original part without the hassle of sending it back.
Installation and Post-Install Procedures
Installation is straightforward for a DIY mechanic with basic tools. The BCM is typically located under the driver’s side of the dashboard. Always disconnect the negative battery terminal before beginning work.
Important Note: While this module is programmed for your vehicle, certain security and safety systems may require a relearn or synchronization procedure after installation. These are standard procedures that can be performed with a professional-grade scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and to satisfy the traction control system.
Always consult a factory service manual or a qualified technician if you are unsure about any step of the installation or post-installation process.

Frequently Asked Questions
Do I need to program this BCM?
No. This BCM comes fully programmed to your vehicle’s VIN before it ships. Just provide your VIN at checkout, and we handle all the programming for you.
Where is the BCM located on my 1999 Silverado 2500?
The Body Control Module is typically located under the driver’s side dashboard, to the left of the steering column.
What is a core charge? Do I have to send my old part back?
There is absolutely no core charge for this part. You are not required to send your original BCM back to us, which saves you time and shipping costs.
My airbag light is on after installing the new BCM. Is it defective?
No, this is a normal security feature. The new BCM needs to be synchronized with your vehicle’s airbag module (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure using a professional scan tool to turn off the light.
Will this fix my truck’s dead battery problem?
If the dead battery is caused by a parasitic draw originating from a faulty BCM (a very common issue), then yes, this part is the correct solution. It will restore the module’s ability to properly enter sleep mode, eliminating the drain.
