Is Your GM Truck or SUV Experiencing Strange Electrical Problems?
If you’re dealing with a vehicle that seems to have a mind of its own—power windows that won’t cooperate, door locks acting erratically, interior lights flickering, or a security system that randomly activates—the culprit is often a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and unpredictable issues. This isn’t just an inconvenience; it can affect the safety and security of your vehicle.
The Direct-Fit, Programmed Solution
Instead of spending a fortune at the dealership for a new module and expensive programming, we offer a straightforward and reliable solution. This Body Control Module, compatible with service number 19208539, is professionally prepared and programmed specifically for your vehicle. Simply provide us with your 17-digit Vehicle Identification Number (VIN) during checkout, and we will flash the module with the latest GM software updates tailored to your exact make and model. This ensures a seamless, plug-and-play installation process, getting you back on the road without the need for a trip to the dealer for programming.
From the Diagnostic Bay
We once had a 2000 GMC Sierra in the shop with the most bizarre symptoms. The owner said his dome light would stay on for minutes after closing the door, his power locks only worked from the passenger side, and the radio would sometimes refuse to turn off after he took the key out. We checked grounds, relays, and switches, but everything tested fine. It was a classic case of a confused BCM. Swapping in a pre-programmed module like this one solved every single issue in under 30 minutes. It’s amazing how this one component can restore sanity to a vehicle’s entire electrical system.
Symptoms of a Failing 2001 Bravada Body Control Module
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ The security system or alarm activates for no reason, or the “Security” light stays illuminated on the dash.
- ✔ Interior or exterior lights (headlights, dome lights, dash lights) flicker, stay on, or don’t turn on at all.
- ✔ The horn honks unexpectedly.
- ✔ Wipers operate erratically or won’t turn off.
- ✔ Communication errors with other modules, leading to various warning lights.
- ✔ Radio or climate control malfunctions.
Installation and Post-Install Procedures
Physical installation is typically straightforward, involving disconnecting the battery and swapping the old module with this new one. However, due to the integration of various vehicle systems, some post-installation steps may be necessary:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new 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 to satisfy the traction control system.
We always recommend consulting a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors a wide range of non-engine-related functions, such as power windows, locks, lights, wipers, security system, and interior accessories. It acts as a central hub for these electronic systems.
Do I need to get this module programmed by a dealer?
No. We handle the programming for you before we ship the part. Just provide your vehicle’s 17-digit VIN when you order, and the module will arrive ready for installation, flashed with the latest GM software for your specific vehicle.
Where is the BCM located on my 2001 Bravada?
On the 2001 Oldsmobile Bravada, as well as the S10 and Blazer, the BCM is typically located behind the center of the dashboard, often near the radio or climate controls. On the full-size trucks and SUVs like the Silverado and Tahoe, it’s usually on the driver’s side (LH) of the dash.
What if my airbag light turns on after I install the BCM?
This can happen because the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A technician with a professional-grade diagnostic tool will need to perform a quick procedure called “Setup SDM Primary Key in BCM” to sync the modules and turn off the light.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module without needing to send it back to us.
