Is Your GM Truck Experiencing Strange Electrical Issues?
If you’re dealing with flickering lights, power windows with a mind of their own, or a security system that won’t let you start your own vehicle, you’re likely facing a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems. Don’t let electrical gremlins sideline your reliable S10, Jimmy, Silverado, or Sierra. This is the direct, pre-programmed solution you need to restore order and get your truck back to full functionality.
Common Symptoms of a Failing BCM
- ✔ Erratic power window or door lock operation.
- ✔ Interior lights (dome, dash) staying on, flickering, or not working at all.
- ✔ Horn sounding randomly or failing to work when needed.
- ✔ Vehicle security system (Passlock) issues, causing a no-start condition with a flashing security light.
- ✔ Wipers activating on their own, not parking correctly, or not turning off.
- ✔ Inoperative radio or climate control functions.
- ✔ False warnings on the instrument cluster.
- ✔ Communication error codes when scanned with a diagnostic tool.
Your Direct-Fit 1998-2000 Blazer S10 BCM Solution
This isn’t a used part from a salvage yard with an unknown history. This is a dependable Body Control Module, meticulously programmed to your vehicle’s specific 17-digit VIN before it ships. We load the latest, most stable software updates from GM, which often corrects factory flaws and improves performance. This critical programming step ensures that the module communicates perfectly with your truck’s other systems, like the Engine Control Module (ECM) and instrument cluster, right out of the box. You get a reliable part that is ready for installation, saving you a costly trip to the dealership for programming.
Simple Installation Process
Installation is straightforward for a DIY mechanic or any professional technician. The BCM is typically located under the driver’s or center dash area. Once the old module is removed, this one plugs directly into the factory wiring harnesses. Because we handle the programming, most functions will be restored immediately. However, on some vehicles, additional synchronization may be needed.
- Airbag System Sync: If your airbag warning light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag module and can be performed by any shop with a professional-grade scan tool.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control operation.
Best of all, there is no core charge. You can keep your original module without the hassle of shipping it back.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, door locks, interior and exterior lighting, the security system, wipers, and the horn.
Is this module truly plug-and-play?
Yes, for the vast majority of functions. We pre-program it to your VIN so it communicates correctly with your truck. In some cases, as noted above, a simple relearn procedure for the airbag or brake system may be required by a technician with a capable scan tool.
How do I provide my VIN?
After you complete your purchase, please send us your 17-digit Vehicle Identification Number (VIN). You can typically reply to your order confirmation email or find a ‘contact seller’ option. We cannot ship your module until we receive the VIN.
Will this fix my ‘Security’ light and no-start problem?
A faulty BCM is one of the most common causes of GM Passlock security system failures. This often results in a flashing security light and an engine that cranks but won’t start. A correctly programmed BCM is the definitive solution for this issue.
My original part number isn’t on your list, but my vehicle is. Will this work?
Yes. GM often uses many different part numbers for the same physical module over a vehicle’s production run. As long as your make, model, and year are listed, this is the correct BCM. Our VIN programming ensures it functions perfectly for your specific vehicle options.
