Tired of Chasing Electrical Gremlins in Your Truck?
If you’re dealing with flickering lights, unresponsive power windows or locks, a security light that won’t turn off, or other bizarre electrical issues in your 1998 S10, Sonoma, or Blazer, a failing Body Control Module (BCM) is the most likely culprit. This isn’t just an annoyance; it’s a reliability issue that can leave you stranded. Stop throwing parts at the problem and get the definitive solution that restores your truck’s factory functions and your peace of mind.

Expert Insight: Why Pre-Programming is a Game-Changer
As a technician, I’ve seen countless owners get stuck after installing a generic, un-programmed BCM. The truck won’t start, or half the accessories won’t work, leading to a frustrating tow to the dealer and an expensive programming bill. Our service eliminates that entire headache. By handling the programming for this 1998 S10 programmed BCM before it even ships, we’re giving you a dealership-level solution at a fraction of the cost and hassle. It’s the smartest way to complete this repair, especially for the DIY mechanic who values their time and money.
Important Post-Installation Information
While this 1998 S10 programmed BCM is designed for a simple install, some vehicles may require one of the following procedures to finalize the synchronization with other vehicle systems. This is normal and ensures all components communicate correctly.
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and traction control performance.
Always consult a factory service manual or a qualified technician if you are unsure about any step of the installation process.
Frequently Asked Questions
How does the VIN programming process work?
It’s simple. After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. Our technicians use this number to access the latest official GM software for your specific truck and flash it onto the BCM. This ensures it works perfectly with the options your vehicle was built with.
Is this BCM guaranteed to fix my specific electrical problem?
This 1998 S10 programmed BCM corrects issues directly caused by a failing Body Control Module, such as problems with power accessories, security systems, and interior lighting. While it is the most common cause for these symptoms, we always recommend proper vehicle diagnostics to confirm the BCM is the source of the fault before ordering.
What if my original part number isn’t on the list?
The part numbers listed (09366803, 16264870, 16268395, etc.) are the most common for these models. If your part number is different, please contact us with your VIN and original part number before ordering. We can verify compatibility to ensure you receive the correct module.
Is this part truly ‘plug and play’?
Yes, because we handle the programming, the module is electronically ready to be installed. However, as noted in the description, some vehicles may require a simple relearn procedure (like for the airbag or brake systems) with a scan tool to fully sync the new module with other systems in the truck. This is a normal part of replacing modern vehicle electronics.
Do I need to return my old BCM?
No. This product has no core charge. You can keep, recycle, or dispose of your original module at your convenience.
What kind of warranty is included?
This unit is backed by our one-year replacement warranty, giving you confidence and protection for your purchase.
