Restore Your SUV’s Electrical Stability and Functionality
Are you chasing down electrical gremlins in your 1998 Oldsmobile Bravada, Chevy S10 Blazer, or GMC S15 Jimmy? Intermittent power windows, flickering lights, or a security system that has a mind of its own are classic signs of a failing Body Control Module (BCM). This isn’t just an annoyance; it’s a breakdown in your vehicle’s central nervous system. As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable truck into a source of constant frustration. This replacement BCM is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a straightforward and effective repair.
A Technician’s Notebook
I remember a 1998 GMC Jimmy that came into the shop with a laundry list of bizarre issues. The dome light wouldn’t turn off, the driver’s side power lock worked only half the time, and the radio would randomly shut down. The owner had already replaced the battery and checked all the fuses. After hooking up the scan tool, I noticed communication errors with several accessory modules. This pointed directly to the central hub: the BCM. Once we swapped in a correctly programmed module, every single one of those ghost-in-the-machine problems vanished. This is why a quality, correctly configured 1998 Bravada BCM is critical—it solves the root cause, not just the symptoms.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional interior/exterior lights.
- ✔ Power windows or door locks working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ The radio or other dashboard accessories shutting off unexpectedly.
- ✔ False warning lights appearing on the instrument cluster.
- ✔ Communication error codes (U-codes) stored in the diagnostic system.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On most of these models (Bravada, Blazer, Jimmy), the BCM is located in the center of the dashboard, often behind the glove box or a lower dash panel. On the Isuzu Hombre, it’s typically on the driver’s side (LH dash).
- ✔ Remove the Old Module: Carefully unplug the electrical connectors and unbolt the original BCM from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM and securely reconnect all electrical harnesses.
- ✔ Power Up: Reconnect the negative battery terminal. Turn the ignition to the ‘ON’ position and verify that your lights, locks, and windows are now functioning correctly.
Post-Installation System Checks
Your new BCM comes programmed and ready to go, but in some cases, your vehicle’s other systems may need to be re-synchronized. This is a normal part of the process. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the airbag module with the new BCM and must be done with a professional-grade scan tool.
- Brake Pedal Position Relearn: To ensure your brake lights and traction control system are working as intended, a brake pedal position sensor recalibration might be necessary on some models.
We make it simple: No Core Charge! You don’t need to send your old, faulty module back to us.

Frequently Asked Questions
Do I need to send you my VIN?
Yes. To ensure 100% correct functionality, we flash this BCM with the latest GM software using your vehicle’s specific VIN. Please provide your VIN during or after checkout.
Is this a plug-and-play installation?
Mostly, yes. Because it comes pre-programmed, you will not need a dealership to program it. However, as noted above, a simple airbag or brake sensor relearn procedure may be required post-installation, which sometimes needs a scan tool.
Where is the BCM located on my 1998 Bravada?
On the 1998 Oldsmobile Bravada, the Body Control Module is typically found behind the passenger side of the dashboard, often accessible by removing the glove box assembly.
Do I need to return my old BCM?
No. This product has no core charge, so you can keep your original module without any extra fees or hassle.
Will this fix my security light issue?
A failing BCM is a very common cause of security system malfunctions, including a constantly lit or flashing security light and no-start conditions. Replacing it with this programmed unit is a highly effective fix for these problems.
