Restore Full Electrical Function to Your GM Truck
Is your 1999-2000 GMC Sierra or Chevrolet Silverado plagued by bizarre electrical issues? Flickering lights, malfunctioning power windows, a security system that acts on its own, or warning lights that won’t turn off are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your truck’s body electronics, and when it fails, it can create a cascade of frustrating and unpredictable problems. This isn’t just an inconvenience; it can affect the safety and reliability of your vehicle. Don’t let a faulty module keep your truck off the road. This direct-fit replacement BCM is the definitive solution to restore your vehicle’s electronic stability and performance.
We take the guesswork and high dealership costs out of the equation. Each BCM is meticulously programmed to your truck’s specific Vehicle Identification Number (VIN) before it ships. This crucial step ensures that the module communicates perfectly with your truck’s existing systems, including the engine computer, anti-theft system, and optional equipment. This VIN-specific programming makes installation as straightforward as possible, eliminating the need for expensive dealer-only programming tools or additional trips to a specialized repair shop. Simply provide your VIN at checkout, and we handle the complex software configuration for you.
Common Symptoms of a Failing Sierra 1500 BCM
If you’re experiencing any of the following issues, a faulty Body Control Module is the most likely culprit. The BCM controls a wide range of functions, so symptoms can be varied and seem unrelated. Verifying one or more of these problems is a strong indicator that it’s time for a replacement.
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from the interior dome lights or exterior courtesy lights (staying on or not turning on).
- ✔ The security system or alarm randomly activating or preventing the vehicle from starting.
- ✔ Inconsistent or non-working radio, climate controls, or instrument cluster gauges.
- ✔ False warning lights on the dashboard, such as the ‘Security’ or airbag light.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Wipers operating randomly or not responding to the switch.
- ✔ Communication errors when a diagnostic scan tool is connected.
Installation and Post-Install Procedures
This BCM is located on the driver’s side of the dashboard. Installation is a direct swap, but please note a couple of potential post-installation steps that may be required for your specific vehicle. While our VIN programming covers the majority of the setup, certain security and safety systems may require a final handshake procedure.
- Airbag System Sync: In some cases, the new BCM may need to be synchronized with the vehicle’s existing Supplemental Inflatable Restraint (SIR) system. If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible professional scan tool. This is a security measure to ensure the systems communicate correctly.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be necessary to ensure proper brake light operation and to satisfy the inputs for the traction control and anti-lock brake systems.
We make it even easier with a no core charge policy. You don’t need to worry about the cost or hassle of sending your old, faulty module back to us. Keep it, recycle it, or dispose of it as you see fit.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, the security system, wipers, and the instrument cluster.
Why do you need my VIN?
We require your Vehicle Identification Number (VIN) to program the BCM with the exact software and calibrations for your truck’s specific features and options. This ensures it works correctly right out of the box and communicates properly with other modules in your vehicle.
Is this a plug-and-play part?
Because we pre-program it to your VIN, it is as close to plug-and-play as possible. However, as noted in the description, some vehicles may require a simple ‘relearn’ or ‘sync’ procedure for the airbag or brake systems, which can be done with a professional scan tool.
Can I install this myself?
Yes, if you have basic mechanical skills, you can physically install this module. It is typically located under the driver’s side dashboard. The most important part is ensuring you have access to a scan tool capable of performing the post-install procedures if they are needed for your vehicle.
What happens if the airbag light is on after I install it?
If the airbag light comes on, it means the new BCM needs to be formally introduced to the airbag’s computer (SDM). A mechanic with a bi-directional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the two modules and turn off the light.
Do I need to return my old BCM?
No. This product comes with no core charge. You can keep your original module without any additional fees or hassle.
