End the Electrical Headaches in Your GM Truck or SUV
Are strange electrical problems plaguing your Chevy S10, Blazer, or GMC Jimmy? Flickering lights, power windows with a mind of their own, or a security system that won’t cooperate are more than just annoyances—they’re signs of a failing Body Control Module (BCM). This vital component is the central hub for your vehicle’s body electronics, and when it fails, it can make your trusted truck feel unreliable.

An Expert’s Note on GM’s Passlock System
“One of the most frustrating issues for owners of these late-90s GM trucks is the dreaded ‘Security’ light. Your truck cranks but won’t start, leaving you stranded. This is often caused by the BCM failing to recognize the key’s transponder. The BCM is the heart of the Passlock/VATS system. When we program this 1998-2000 Blazer S10 BCM to your VIN, we are restoring that critical security handshake, providing a reliable fix for a very common and costly problem.”
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
Is this BCM truly “plug and play”?
Yes, because we program it to your specific VIN before shipping, it is designed to be a plug-and-play installation. However, as with any complex electronic part, some vehicles may require a simple post-installation procedure, like an airbag system sync, if a warning light appears. We provide clear instructions for these potential steps.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is essential for the module to work in your truck.
What if my airbag light comes on after installation?
In some cases, the new BCM may need to be synchronized with the airbag system’s computer (SDM). This is done with a procedure called ‘Setup SDM Primary Key in BCM’ using a professional scan tool. It’s a quick process for any qualified technician.
Will this fix my “Security” light and no-start problem?
Yes, a faulty BCM is one of the most common causes of Passlock security system failures in these vehicles. A new, properly programmed 1998-2000 Blazer S10 BCM is the correct fix for this specific issue.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep or dispose of your original module at your convenience.
