Restore Full Electrical Control to Your 1998 GM Truck
Are you battling frustrating and unpredictable electrical problems in your 1998 Chevrolet Blazer, S10, GMC Jimmy, or a related model? Issues like flickering interior lights, malfunctioning power windows and locks, a faulty security system, or intermittent warning lights on the dash are often traced back to a single point of failure: the Body Control Module (BCM). This component acts as the central hub for your vehicle’s body electronics, and when it fails, it can create a cascade of confusing and annoying symptoms. This replacement BCM is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
Is Your 1998 Blazer S10 Exhibiting These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, a faulty Body Control Module is the most likely culprit:
- ✔ Erratic or non-functional interior and exterior lighting (dome lights, headlights, taillights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system engaging randomly or preventing the vehicle from starting.
- ✔ The radio or other dashboard accessories turning on and off unexpectedly.
- ✔ False warnings on the instrument cluster, such as a persistent “door ajar” light.
- ✔ Inconsistent or non-working windshield wipers.
- ✔ Communication issues with diagnostic scan tools.

Installation and Post-Install Considerations
This BCM is typically located in the center dash area. While installation is generally a direct swap, please be aware of a few potential post-installation procedures that may be necessary depending on your specific vehicle’s configuration.
- Airbag System Sync: If the airbag warning light is illuminated 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: In some cases, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation.
Disclaimer: Specific procedures can vary. We always recommend consulting a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
How does the VIN programming process work?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. Our technicians use this number to load the correct, vehicle-specific software and calibrations onto the BCM before it ships. This ensures it works correctly with your truck’s existing systems.
Is this part difficult to install myself?
For someone with moderate mechanical experience, the installation is straightforward. The BCM is usually located under the dashboard. The primary task involves disconnecting the battery, removing some trim panels for access, and swapping the electrical connectors. However, as post-installation procedures may require a professional scan tool, we recommend consulting a service manual or a qualified mechanic if you are unsure.
What if my airbag light is on after I install the BCM?
This is a known possibility. The new BCM needs to be electronically ‘introduced’ to the airbag’s Sensing and Diagnostic Module (SDM). This requires a professional-grade scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. Most repair shops can perform this service for you.
Do I need to return my old BCM?
No. This part is sold with no core charge. You can keep your original module, which saves you the time and expense of return shipping.
Will this fit my 1998 GMC Sonoma?
Yes, this BCM is compatible with the 1998 GMC Sonoma, as well as the Chevy S10, Blazer, GMC Jimmy, Oldsmobile Bravada, and Isuzu Hombre, as long as the original part number matches one of the numbers listed in the description.
