Restore Full Electrical Function to Your Truck with a Reliable BCM
Are you dealing with baffling electrical problems in your 1998 Isuzu Hombre, S10, or Blazer? Intermittent power windows, flickering interior lights, or a security system that acts up on its own are classic signs of a failing Body Control Module (BCM).

This replacement 1998 Isuzu Hombre BCM is the dependable solution you need to get everything working correctly again.

This ensures seamless integration with your vehicle’s existing systems, saving you a costly trip to the dealer for programming.
A Technician’s Notebook
I remember a 1998 S10 that came into the shop with a list of symptoms that had the owner chasing his tail for weeks. The radio would turn off, the dome light would stay on, and the power locks worked only when they felt like it. He had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw communication errors pointing directly to the BCM. We installed a pre-programmed module just like this one, and in under an hour, every single issue was resolved. He was thrilled to have his truck back to normal without the massive bill and wait time from the dealership.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ The security or anti-theft system preventing the vehicle from starting.
- ✔ Intermittent windshield wiper operation or wipers that won’t park correctly.
- ✔ The horn sounding unexpectedly or not working when pressed.
- ✔ Malfunctioning radio or climate control displays.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes to ensure all systems are powered down.
- ✔ Locate the BCM: On the 1998 Isuzu Hombre, the BCM is typically located on the left-hand (driver’s) side of the dashboard. On S10/Blazer/Jimmy models, it’s usually behind the center dash area.
- ✔ Remove Trim Panels: Carefully remove any plastic trim or panels necessary to access the module.
- ✔ Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have release tabs that need to be pressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New BCM: Mount the new, pre-programmed BCM in the same location and securely plug in all the electrical connectors.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all related functions—lights, locks, windows, wipers, etc.—to confirm the repair.
Important Post-Installation Information
While this module is programmed for your VIN, some vehicles may require additional synchronization steps after installation. Please be aware of the following possibilities:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool to sync the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light and traction control operation.
Disclaimer: These procedures can vary. Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship the part until we have programmed it.
What does the BCM actually control?
The Body Control Module acts as the brain for most of your vehicle’s non-engine related electronics, including power windows, locks, interior and exterior lighting, the security system, wipers, and the horn.
Will this fix my ‘Service Engine Soon’ light?
No, the BCM does not control engine functions. The ‘Service Engine Soon’ or ‘Check Engine’ light is related to the Engine Control Module (ECM) or Powertrain Control Module (PCM).
Is a special tool required for the airbag light?
Yes, if the airbag light comes on after installation, it requires a professional bidirectional scan tool capable of performing the ‘Setup SDM Primary Key in BCM’ procedure. Most basic code readers cannot do this.
