Is Your GM Vehicle Plagued by Electrical Gremlins?
Are you dealing with flickering lights, power windows that have a mind of their own, or a security system that randomly activates? These frustrating and unpredictable issues often point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, managing everything from interior lighting and power locks to the anti-theft system. When it starts to fail, it can create a cascade of bizarre electrical problems that can be difficult to diagnose.
Symptoms of a Failing Body Control Module
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Headlights, taillights, or interior lights behaving erratically (staying on, not turning on, or flickering).
- ✔ The security or anti-theft system light is on, or the alarm goes off randomly.
- ✔ A parasitic battery drain that kills your battery overnight.
- ✔ The horn honking unexpectedly.
- ✔ Inaccurate or non-working gauges on the instrument cluster.
- ✔ A no-start condition where the engine cranks but won’t fire, often accompanied by a security light.

The biggest advantage? We handle the programming for you. Dealerships charge a premium for a new module and then add on expensive programming fees. We eliminate that hassle and cost. Simply provide us with your vehicle’s VIN during checkout, and we will program the module with the latest GM software updates specific to your vehicle. It arrives at your door ready for a straightforward installation.
This module is a direct replacement for service numbers 19208539, 9371990, and 9385236, ensuring broad compatibility with models like the Chevy Astro, Silverado, Tahoe, S10, GMC Safari, Sierra, Yukon, and more. Check the fitment list to confirm compatibility with your exact vehicle.
Installation and Post-Install Considerations
Installation is typically simple. On most compatible vehicles, the BCM is located on the left-hand (driver’s) side of the dashboard. Once the new module is installed, your vehicle should start and run. However, depending on your specific model and options, a couple of additional steps may be needed:
- Airbag System Sync: If your airbag warning light illuminates after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system and must be performed with a professional-grade scan tool.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control function.
We make the process even easier with our No Core Charge policy. You don’t have to worry about the cost or hassle of sending your old, faulty module back to us. Keep it, recycle it, or dispose of it as you see fit.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, interior/exterior lights, the security system, wipers, and more.
Do I need to program this BCM?
No. We program the module to your vehicle’s specific VIN before shipping it to you. It arrives ready to be installed, saving you a costly trip to the dealership.
Where is the BCM located on my 2001 Astro or 2000 Silverado?
On most compatible models, including the Astro, Safari, Silverado, and Sierra, the BCM is located behind the dashboard on the driver’s side, often near the steering column or parking brake pedal.
What if the airbag light is on after I install the module?
This is a normal possibility. The new BCM needs to be electronically ‘introduced’ to the airbag system. A technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Is this part compatible with service number 9371990?
Yes, this module is a direct, compatible replacement for service numbers 9385236, 19208539, and 9371990, ensuring it will function correctly in vehicles that originally used any of those parts.
Do I need to send my old part back?
No. This part is sold with no core charge. You can keep your original module without any extra fees or hassle.
