Is Your GM Truck or SUV Experiencing Strange Electrical Problems?
If your 2000-2001 Silverado, Sierra, Tahoe, or other compatible GM vehicle is acting possessed, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics. When it starts to fail, it can cause a cascade of frustrating and unpredictable issues, from flickering lights to a vehicle that won’t start. Don’t let a faulty module keep you off the road. This direct-fit BCM is the reliable, straightforward solution to restore your vehicle’s proper function.
From the Diagnostic Bay
We had a 2000 GMC Sierra in the shop where the owner had replaced the battery twice and the alternator once, trying to solve an intermittent no-start and a parasitic battery drain. The dome lights would randomly stay on, and the power locks worked only when they wanted to. After confirming the charging system was healthy, we traced the issue to a faulty BCM. It was sending erratic signals, keeping other modules awake and draining the battery overnight. Installing a VIN-programmed BCM like this one solved all the issues in one go, saving the customer from further expensive and incorrect repairs.
Symptoms of a Failing Body Control Module
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that won’t turn on or off, or flicker randomly.
- ✔ The security system or alarm acting up, preventing the vehicle from starting (PassLock issues).
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Wipers behaving erratically or not parking in the correct position.
- ✔ Warning lights on the dashboard, such as the airbag or brake light, for no apparent reason.
- ✔ A persistent parasitic battery drain that leaves you with a dead battery.
The Plug-and-Play Solution for Your 2000 Silverado BCM
Dealer service for a BCM replacement can be a costly and time-consuming ordeal. You’re often required to have your vehicle towed in for installation and expensive programming. We eliminate that hassle. This module is a genuine, tested component that we program specifically to your vehicle’s Vehicle Identification Number (VIN) before it ships. This ensures it communicates perfectly with your truck’s existing systems right out of the box. We load the latest GM software updates, which can resolve issues the original factory programming may have had. This is a true plug-and-play repair that you can perform in your own driveway.
This module is a direct replacement for part numbers 19208539, 9371990, and 9385236. Simply confirm the part number on your original module to ensure compatibility.
Installation and Post-Install Considerations
Physical installation is typically straightforward, as the BCM is located under the driver’s side dash. However, after the new module is installed, some vehicles may require additional synchronization procedures. Please be aware of the following:
- Airbag System Sync: If your airbag warning light is illuminated 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.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and traction control function.
We make the process simple: After your purchase, just send us your vehicle’s VIN, and we’ll handle the rest. And with our no-core-charge policy, you can keep your original module without any extra fees.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before we ship it to you. This makes the installation process much simpler, saving you a trip to the dealership.
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors many of its non-engine-related electronic functions. This includes power windows, locks, lights, wipers, security system, and more.
Where is the BCM located on my 2000 Silverado or Sierra?
On most compatible models like the 2000 Silverado, Sierra, Tahoe, and Suburban, the BCM is located under the driver’s side of the dashboard, to the left of the steering column.
What happens if the airbag light comes on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag’s computer (SDM). A qualified technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old BCM back to us.
