Are you chasing electrical gremlins in your GM truck or SUV? Flickering lights, dead power windows, a security light that won’t turn off, or gauges going haywire are classic signs of a failing Body Control Module (BCM). It’s the central command for your vehicle’s body electronics, and when it goes, it can cause a host of frustrating and confusing problems. In my 20+ years as a technician, I’ve seen these exact issues countless times, often leading owners down a rabbit hole of expensive and incorrect diagnoses.
This isn’t just a replacement part; it’s a direct solution. We provide a reliable Body Control Module, compatible with part numbers 19208539, 9371990, and 9385236. The best part? We flash it with the latest GM software and program it specifically to your vehicle’s VIN before we ship it. This means you can skip the expensive trip to the dealership for programming. It’s a straightforward fix that restores the functionality you depend on every day.
Case Study: A Tricky Diagnosis
A customer brought in a 2000 Silverado 1500 with an intermittent no-start and a security light that stayed on. They had already replaced the battery and ignition switch with no luck. After connecting my scan tool, I noticed multiple U-codes (communication errors) pointing to the BCM. Instead of communicating properly, the module was sending erratic signals, preventing the vehicle from starting. By installing a pre-programmed 2000 Yukon Body Control Module (which is cross-compatible), we resolved all the electrical faults in one go, saving the customer hundreds in further diagnostic time.
Is Your GM Truck Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Erratic or non-functional interior/exterior lights
- ✔ Power windows, locks, or mirrors not working
- ✔ Horn honking randomly or not at all
- ✔ Gauges on the instrument cluster behaving strangely or not working
- ✔ The security or anti-theft system light stays on, preventing the engine from starting
- ✔ Communication-related Diagnostic Trouble Codes (DTCs) like U0140, U0155, or other U-codes
- ✔ Intermittent issues that seem to have no logical cause
A Straightforward Guide to Installation
Installing your new BCM is a manageable job for a confident DIYer. While the exact location can vary slightly by model, it’s typically found under the driver’s side of the dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On most of these trucks and SUVs, it’s mounted to the left of the steering column, often behind a lower dash panel. You may need to remove a plastic trim piece for access.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module from its mounting bracket.
- Install the New Module: Seat the new, pre-programmed BCM into the mounting bracket and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—lights, windows, locks, wipers, etc.—to confirm the repair.
Important Post-Installation Notes
Because this 2000 Yukon Body Control Module is pre-programmed, most functions will work immediately. However, depending on your specific vehicle, a couple of simple relearn procedures may be required. This is completely normal.
- ✔ Airbag System Sync: If your 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 system.
- ✔ Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure brake lights and traction control function correctly.

Frequently Asked Questions about this BCM
Frequently Asked Questions
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
Is this part truly plug-and-play?
Yes, it comes programmed to your VIN. In most cases, it is a direct installation. However, as noted, some vehicles may require a simple airbag or brake sensor relearn procedure with a scan tool if a warning light appears.
How do I provide my VIN?
