Is Your 1998 GM Truck Experiencing Strange Electrical Issues?
If the electronics in your 1998 Chevy Blazer S10, GMC Jimmy S15, Oldsmobile Bravada, or Isuzu Hombre are acting possessed, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics, managing everything from your power windows and door locks to the interior lights and security system. When it starts to fail, it can create a cascade of frustrating and unpredictable problems that can make your truck difficult to use and even unsafe to drive.
This is a direct-replacement Body Control Module for part number 16268395, designed to restore your vehicle’s factory functions perfectly. Unlike a generic part from a local store, this module comes fully programmed to your truck’s specific Vehicle Identification Number (VIN). This critical step ensures seamless integration with your vehicle’s existing systems, eliminating the need for an expensive trip to the dealership for programming.
Expert Pro Tip
Expert Pro Tip
Before condemning your BCM, always perform a thorough check of your vehicle’s battery, alternator, and primary ground connections (especially the main ground from the battery to the chassis and engine block). A weak battery or a corroded ground can cause voltage drops that mimic the symptoms of a faulty BCM. A simple voltage test and cleaning of the ground points can sometimes save you the cost of a new module.
Common Symptoms of a Failing 1998 Blazer S10 BCM
A faulty BCM can manifest in numerous ways. If you’re noticing any of the following issues, it’s a strong indication that your body control module needs replacement:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior dome lights staying on or not working at all.
- ✔ The security system or anti-theft light flashing, potentially causing a no-start condition.
- ✔ Dashboard warning lights illuminating randomly.
- ✔ Wipers or radio behaving unpredictably.
- ✔ Inconsistent operation of the heating and A/C blower motor.
- ✔ Communication issues with diagnostic scan tools.

Installation and Post-Install Procedures
The BCM is typically located behind the center of the dash. While installation is a straightforward unbolt-and-replace process, there are a couple of potential procedures you should be aware of after the new module is installed:
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This is because the new BCM needs to be synchronized with the airbag system’s SDM. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light. This is only necessary if the light comes on.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration might be needed. This is a simple procedure that can often be done with a capable diagnostic tool.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.
