Is Your GM Truck or SUV Plagued with Electrical Gremlins?
If you’re dealing with erratic power windows, intermittent door locks, a security light that won’t turn off, or interior lights with a mind of their own, a failing Body Control Module (BCM) is the most likely culprit. In vehicles like your 1998 Oldsmobile Bravada, the BCM acts as the central hub for all body-related electronics. When it fails, it can cause a cascade of frustrating and unpredictable issues that are often misdiagnosed, leading to wasted time and money on unnecessary parts.
From the Diagnostic Bay
We once had a customer with a ’99 Silverado who had replaced every door lock actuator and window switch, yet the problems persisted. The locks would cycle randomly while driving, and the driver’s window would only work occasionally. He was convinced the truck was haunted. After a quick scan, we identified communication faults with the BCM. A new, programmed module fixed every single issue in under 30 minutes. It’s a classic case where the central controller, not the individual components, is the root of the problem.
Common Symptoms of a Failing BCM
- ✔ Power windows, mirrors, or seats not working or operating intermittently.
- ✔ Interior or exterior lights staying on, flickering, or not turning on at all.
- ✔ The security or anti-theft system preventing the vehicle from starting.
- ✔ Erratic or non-functional power door locks and keyless entry.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ The radio or climate control system behaving strangely.

Don’t let a faulty BCM keep you off the road. This is a direct-replacement Body Control Module for a wide range of GM trucks and SUVs. We take the hassle out of the repair by pre-programming the unit to your vehicle’s specific VIN number before it ships. This means no expensive trips to the dealership for programming. It arrives ready for a straightforward installation, loaded with the latest software updates from GM to ensure optimal performance and longevity.
Why Choose Our 1998 Bravada Body Control Module?
This module is the definitive solution for restoring your vehicle’s electronic functions. By providing us with your VIN, you receive a component that is precisely matched to your vehicle’s factory options. This eliminates compatibility guesswork and ensures all systems communicate correctly after installation. This unit is a reliable replacement for multiple part numbers, including 16257125, 19153625, and 8093668010.
Installation and Post-Install Notes
Installation is typically plug-and-play. Locate your old BCM (often in the center or left-hand side of the dash), disconnect the battery, swap the modules, and reconnect the battery. However, in some cases, additional steps may be required:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control functionality.
There is no core charge for this part. You can keep your original module.
Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will receive instructions to reply with your 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your vehicle.
Is this a plug-and-play part?
Yes, for most vehicles. Because it comes pre-programmed to your VIN, it will not require a trip to the dealer for initial setup. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake systems, which can be done with a capable bidirectional scan tool.
Will this fix my specific electrical problem?
This BCM will correct issues directly caused by a faulty module. The symptoms list above covers the most common failures. If you are unsure, it is always best to have a qualified technician diagnose the vehicle to confirm the BCM is the point of failure.
Where is the BCM located on my vehicle?
On most compatible models like the S10, Blazer, and Bravada, the BCM is located in the center dash area. On models like the Silverado, Sierra, and Astro van, it is typically found on the left-hand side of the dash. Always consult a service manual for the exact location.
What if I have an airbag light after installation?
An airbag light is not a sign of a defective part. It simply means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag module (SDM). A technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
