Is Your GM Truck or SUV Suffering from Electrical Gremlins?
If you’re dealing with flickering lights, power windows that have a mind of their own, a security system that won’t cooperate, or random warning lights on your dash, you’re likely facing a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and convenience features. When it starts to fail, it can cause a cascade of frustrating and unpredictable issues that can make your vehicle feel unreliable. Don’t let a faulty module dictate your driving experience. This direct-fit, pre-programmed BCM is the definitive solution to restore full functionality and peace of mind.
The Simple, Dealer-Free Solution for Your 2000 Yukon BCM
Replacing a BCM used to mean a mandatory, expensive trip to the dealership for programming. We’ve eliminated that hassle. When you order from us, we flash this module with the latest official GM software, specifically matched to your vehicle’s unique Vehicle Identification Number (VIN). This ensures that the module communicates perfectly with your truck’s other systems right out of the box. You get a part that is ready for installation, saving you hundreds of dollars in programming fees and diagnostic time. This is the most efficient way to get your Yukon, Sierra, Tahoe, or other compatible GM vehicle back to 100%.
From the Diagnostic Bay
We had a 2000 Sierra 1500 in the shop that was driving the owner crazy. The dome lights would stay on intermittently, the radio would shut off randomly, and the power locks would only work sometimes. He had already replaced the battery and checked all the fuses. We plugged in our scanner and saw a slew of communication error codes all pointing back to one component: the BCM. Instead of a complex wiring issue, it was just the central computer failing. We installed a VIN-programmed BCM just like this one, and in under an hour, every single one of his electrical problems was gone. It’s amazing how one module can cause so much chaos, and how simple the right fix can be.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting (headlights, taillights, dome lights).
- ✔ The security system or keyless entry fails to work correctly.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Warning lights (like the airbag light) appearing on the dashboard for no reason.
- ✔ Radio or climate control systems behaving erratically.
- ✔ Communication errors with other vehicle modules.
Installation and Post-Install Procedures
Physically installing this module is straightforward. It is typically located under the driver’s side of the dashboard. Simply disconnect the negative battery terminal, unplug the electrical connectors from the old BCM, remove it, and install the new one in its place. Reconnect the connectors and the battery.
While our programming handles the majority of the setup, some vehicles may require a simple relearn procedure to sync with other systems. After installation, please be aware of the following potential requirements:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and traction control function.
This module is a direct replacement for service numbers 19208539, 9371990, and 9385236 and fits a wide range of GM models including the Yukon, Tahoe, Suburban, Silverado, Sierra, S10, Blazer, and more. Please verify the part number on your original module to ensure compatibility.
Frequently Asked Questions
Do I need to take this BCM to a dealer for programming?
No. This is the main benefit of our service. We program the module to your vehicle’s VIN before we ship it. It arrives ready to be installed, saving you time and money.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. We will provide clear instructions on how to do this. We cannot ship the part until we have programmed it.
What tools are needed for the installation?
Basic hand tools are typically all that’s needed to access and swap the module. However, for the post-installation procedures like the airbag sync, a professional-grade diagnostic scan tool is required.
Will this fix my specific electrical problem?
This BCM will correct issues directly caused by a faulty Body Control Module. If your vehicle exhibits several of the symptoms listed, there is a very high probability that this part is the solution. Proper diagnosis is always recommended.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module.
