Is Your GM Truck Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows, a haywire security system, or other bizarre electrical issues in your 1998 Oldsmobile Bravada, S10 Blazer, or GMC Jimmy, the culprit is often a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it starts to fail, it can cause a wide range of frustrating and unpredictable problems. Don’t let a faulty module keep you off the road. This is your direct, reliable solution.
The Plug-and-Play Solution for Your 1998 Bravada BCM
We take the guesswork and hassle out of replacing your BCM. Unlike sourcing a part from a junkyard that may have the same issues or buying one that requires an expensive trip to the dealership for programming, this module comes ready for installation. We flash the unit with the latest GM software updates and program it specifically to your vehicle’s Vehicle Identification Number (VIN) before it ships. This ensures compatibility with your truck’s specific options and systems, making the installation process as straightforward as possible.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lights (flickering, staying on, or not turning on).
- ✔ The security or anti-theft system acting up, preventing the vehicle from starting.
- ✔ Gauges on the instrument cluster behaving erratically or not working at all.
- ✔ The radio or climate control system malfunctioning.
- ✔ False warning lights appearing on the dashboard.
Installation and Post-Install Considerations
This BCM is typically located in the center dash area on the Bravada, Blazer, and Jimmy, or on the LH (driver’s side) dash in the Isuzu Hombre. While the physical swap is straightforward for a DIY mechanic, please be aware of a few potential post-installation procedures that may be necessary.
- Airbag System Sync: In some cases, the new BCM may not immediately sync with the airbag’s SDM (Sensing and Diagnostic Module). If your airbag warning light illuminates after installation, a ‘Setup SDM Primary Key in BCM’ procedure will need to be performed with a professional-grade scan tool.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration may be required. This is also performed with a compatible diagnostic tool.
We make the process easier with our no core charge policy. You can keep your original module without the hassle of shipping it back.

Frequently Asked Questions
What does a Body Control Module (BCM) actually do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions. This includes power windows, locks, interior and exterior lighting, the security system, wipers, and sometimes even the instrument cluster and climate controls.
Is this BCM difficult to install?
For someone with moderate mechanical skill, the physical replacement is not overly difficult as it’s usually located under the dashboard. However, please be aware that post-installation procedures like an airbag sync or brake sensor relearn may require a professional scan tool.
What happens if I don’t provide my VIN?
Providing your VIN is mandatory for this part. We cannot ship the module without it, as we program it specifically to match your vehicle’s factory options. This critical step ensures the BCM works correctly upon installation.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module, saving you time and return shipping costs.
My airbag light is on after installing the new BCM. Is the part defective?
No, this is a common occurrence. The new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool to sync the systems and turn off the light.
