Is Your GM Truck or SUV Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows, a haywire security system, or other strange electrical issues in your 2000-2001 GM vehicle, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central command center for your vehicle’s body electronics, coordinating everything from the dome lights and power locks to the windshield wipers and instrument cluster. When it starts to fail, it can create a cascade of frustrating and seemingly unrelated problems, making your reliable truck feel unpredictable.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The security system engaging randomly or the key fob not responding.
- ✔ Intermittent no-start or no-crank conditions.
- ✔ Windshield wipers behaving erratically or not parking in the correct position.
- ✔ False warnings on the instrument cluster, such as the airbag light.
- ✔ Radio or climate control systems turning on or off by themselves.
The Direct Solution: A VIN-Programmed GM BCM
Don’t let a faulty module keep you off the road. This Body Control Module is the definitive solution for your vehicle. We take the hassle and high cost of dealership repairs out of the equation. Simply provide us with your vehicle’s VIN during checkout, and our technicians will program the module with the latest GM-certified software specific to your truck or SUV. This ensures that when the part arrives, it’s a true plug-and-play component. You are not just buying a part; you are buying a complete, ready-to-install solution that restores the functionality you depend on every day.
Installation and Post-Install Considerations
Physically replacing the BCM is typically straightforward, as it’s located under the driver’s side dash. Because our module comes pre-programmed, the most difficult part of the job is already done. However, in some vehicles, additional synchronization procedures may be required after installation:
- Airbag System Sync: If the airbag warning light is illuminated after you install the new BCM, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM) and requires a professional-grade scan tool.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration might be necessary on certain models.
We believe in transparency, and that includes keeping your old parts. There is no core charge for this module. You can keep your original BCM without the hassle of shipping it back.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that controls and monitors most of your vehicle’s non-engine-related electronic functions. This includes power windows, locks, lights, wipers, security system, and more. It’s essential for modern vehicle comfort and convenience features.
Do I need to have this BCM programmed by a dealer?
No. The main benefit of our service is that we program the BCM to your vehicle’s specific VIN before we ship it to you. This eliminates the need for an expensive trip to the dealership for programming, making it a plug-and-play installation.
Where is the BCM located on my 2000-2001 GM truck/SUV?
On most models covered by this part, such as the Silverado, Sierra, Tahoe, and Suburban, the BCM is located under the driver’s side of the dashboard, to the left of the steering column. On S-series trucks and SUVs like the S10 and Blazer, it is often found in the center dash area.
What if my airbag light comes on after I install the new BCM?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to the airbag control module (SDM). A technician with a high-level scan tool will need to perform a ‘Setup SDM Primary Key in BCM’ procedure to sync the two modules and turn off the light.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive the VIN, as the programming is essential for the part to function correctly in your vehicle.
Is there a core charge? Do I need to send my old part back?
No, there is absolutely no core charge. You can keep your old module, which saves you the time and expense of return shipping.
