Restore Full Functionality to Your GM Truck’s Electronics
Are you battling frustrating electrical gremlins in your 1998 Chevrolet S10, GMC Sonoma, or another compatible GM truck? Issues like flickering lights, malfunctioning power windows and locks, or a stubborn anti-theft system that prevents your truck from starting are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing and unpredictable problems. This replacement Body Control Module, part number 8093668030, is the definitive solution to restore your truck’s reliability and convenience.
The Plug-and-Play Solution for a Complex Problem
Replacing a BCM used to mean a costly trip to the dealership for programming and calibration. We eliminate that hassle. When you order from us, we flash the module with the latest GM software updates and program it specifically to your vehicle’s VIN before it ever leaves our facility. This ensures that the BCM communicates perfectly with your truck’s existing components right out of the box. You get a direct-fit, correctly configured part ready for a straightforward installation, saving you time, money, and the headache of a dealership visit. This is the most efficient way to get your 1998 S10 Sonoma BCM replaced and your truck back to 100%.
From the Diagnostic Bay
We had a ’98 Blazer come in that was driving the owner crazy. The dome light would stay on, the radio would randomly shut off, and the power locks had a mind of their own. He had already replaced the battery and checked all the fuses. We connected our scanner and saw a slew of communication error codes all pointing back to the BCM. Instead of a complex wiring chase, we installed a VIN-programmed BCM. The moment it was connected and the battery was hooked back up, every single issue was gone. It’s a reminder that sometimes the most chaotic-seeming electrical problems have a single, central cause.
Common Symptoms of a Failing 1998 S10 Sonoma BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (staying on, not turning on, or flickering).
- ✔ The security or anti-theft light is on, and the vehicle may not start.
- ✔ Windshield wipers operating incorrectly or activating on their own.
- ✔ Instrument cluster gauges behaving erratically or warning lights appearing for no reason.
- ✔ The radio or climate control system malfunctioning.
- ✔ A constant drain on the battery when the vehicle is off.
Installation and Post-Install Considerations
This BCM is typically located in the center of the dashboard. While the physical installation is straightforward for a DIY-savvy owner, there are a couple of potential post-installation procedures to be aware of. Because the BCM communicates with other critical modules, a relearn or sync process may be necessary in some cases.
- Airbag System Sync: If your airbag warning light illuminates 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 system’s Sensing and Diagnostic Module (SDM). This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure proper brake light and traction control operation.
We always recommend consulting a factory service manual or a qualified technician if you are unsure about any part of the installation process.

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, locks, lights, wipers, the security system, and the instrument cluster.
Is this BCM truly plug-and-play?
Yes, for most functions. We pre-program it to your VIN so it communicates with your truck’s systems correctly. However, as noted, in some cases a secondary procedure like an airbag system sync may be required if a warning light appears after installation.
Where is the BCM located on my 1998 S10 or Blazer?
The BCM is typically located behind the dashboard, in the center area, often near the radio or climate controls. Access usually requires removing some of the dash trim panels.
What happens if I don’t provide my VIN?
Providing your VIN is mandatory for this part. We cannot program the BCM without it, and an unprogrammed module will not function correctly in your vehicle. Your order will be placed on hold until the VIN is received.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
