Is Your GM Truck Experiencing Bizarre Electrical Problems?
If your 2000 GMC Sierra 2500, Silverado, Tahoe, or another compatible GM vehicle is acting possessed, you’re not alone. Flickering lights, malfunctioning power windows, a security system that won’t cooperate, or random warning lights on the dash are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it starts to fail, it can create a cascade of frustrating and seemingly unrelated issues. Don’t let these electrical gremlins sideline your vehicle. This direct-fit, VIN-programmed BCM is the definitive solution to restore order and functionality.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security system or keyless entry system behaving erratically.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Dashboard warning lights (like the airbag light) illuminating for no reason.
- ✔ Communication errors when a diagnostic scan tool is connected.
- ✔ Wipers operating on their own or not responding to the switch.

Installation and Post-Install Considerations
Physically swapping the BCM is typically a simple process, as it’s often located under the driver’s side of the dashboard. However, after the new module is installed, a couple of system relearn procedures may be necessary to ensure all vehicle systems communicate correctly. These are not required on every vehicle but are important to be aware of:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible high-level scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure proper operation of the brake lights and traction control system.
We always recommend consulting a factory service manual or a qualified technician if you are unsure about these procedures. Proper installation ensures the longevity and performance of your new BCM.
Frequently Asked Questions
What does a Body Control Module (BCM) actually 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, wipers, security system, and interior accessories.
Do I need to get this BCM programmed by a dealer?
No! That’s the key benefit of our service. We program the module to your vehicle’s specific VIN before we ship it to you. It arrives ready to be installed, saving you time and money.
Where is the BCM located on my 2000 Sierra or Silverado?
On most of these GM trucks and SUVs, the BCM is located under the driver’s side of the dashboard, to the left of the steering column.
What if my airbag light comes on after I install it?
This can happen. It means the new BCM needs to be electronically introduced to the airbag module (SDM). A professional technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
