Restore Full Electrical Control to Your GM Truck or SUV
Are you battling strange and frustrating electrical issues in your 2000 GMC Yukon, Chevy Silverado, or other compatible GM vehicle? Flickering lights, unresponsive power windows, a security system that acts on its own, or warning lights that won’t go away are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can create a cascade of problems that are difficult to diagnose. This isn’t just an inconvenience; it can affect the safety and reliability of your vehicle.
This replacement Body Control Module, compatible with part numbers 9371990, 19208539, and 9385236, is the definitive solution to these electrical gremlins. Unlike a generic part from a local store, this BCM is delivered to you fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). We flash it with the latest, most stable software updates directly from GM, ensuring it communicates perfectly with your vehicle’s other computers right out of the box. This critical programming step eliminates the need for an expensive trip to the dealership for setup, saving you time and money.
From the Diagnostic Bay
We had a 2000 Silverado 1500 in the shop that was driving the owner crazy. The battery would be dead every few days for no apparent reason. We checked for parasitic draws and found an intermittent one linked to the interior lights, which would sometimes stay on faintly after the doors were locked. The owner had already replaced the battery twice. After hours of tracing wires, we hooked up a high-level scanner and saw erratic data coming from the BCM. It was failing to properly put all the accessory circuits to ‘sleep’ after the key was off. We installed a VIN-programmed BCM just like this one, and the problem was solved instantly. The truck has been starting reliably ever since. It’s a perfect example of how a faulty BCM can manifest in ways you wouldn’t initially expect.
Is Your Body Control Module Failing?
A failing BCM can cause a wide range of symptoms that may seem unrelated at first. If your vehicle is experiencing several of the issues below, your BCM is the most likely culprit. This programmed 2000 Yukon BCM is designed to resolve these exact problems.
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security system or anti-theft light (Passlock) acting up, sometimes causing a no-start condition.
- ✔ The horn honking randomly or not working when you press it.
- ✔ Erratic behavior from the radio or climate control systems.
- ✔ False warnings on the dashboard, such as ‘door ajar’ or other alerts.
- ✔ Unexplained battery drain that leaves you with a dead battery.
The Importance of VIN Programming
Your vehicle is a complex network of computers that need to communicate seamlessly. The BCM is a key player in this network, managing everything from your key fobs to your airbag system. Simply installing a used or non-programmed BCM will not work. It won’t have the correct software for your vehicle’s specific options and security protocols. Our process ensures that the module you receive is a perfect match. By providing us with your VIN during checkout, you guarantee that your new 2000 Yukon BCM is ready for installation, prepared to integrate flawlessly with your truck’s existing systems.
Installation and Post-Install Procedures
This BCM is typically located on the left-hand (driver’s) side of the dashboard. While the physical replacement is straightforward for a seasoned DIYer or any professional technician, some vehicles may require simple electronic relearn procedures after installation. These are not programming steps but rather synchronization tasks that allow other modules to recognize the new BCM.
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This ensures the airbag system (SDM) and the BCM are correctly synced for safety.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure your brake lights and traction control system function correctly.
We make the process simple: purchase the module, provide your VIN, and we handle the complex programming. You receive a part that’s ready to be installed, restoring your vehicle to its proper operational state. Plus, with our no-core-charge policy, you can keep your old module without any extra hassle or fees.
Frequently Asked Questions
Why do I need to provide my VIN?
Your vehicle’s VIN (Vehicle Identification Number) allows us to program the BCM with the exact software and settings for your specific model, trim, and options (like power seats, keyless entry, etc.). This ensures the module works correctly right out of the box without requiring a trip to the dealer for expensive programming.
Is this part difficult to install?
The physical installation is generally straightforward for someone with moderate mechanical skill. It’s usually located under the driver’s side dashboard. However, some post-installation electronic ‘relearn’ procedures, like for the airbag or brake systems, may be required and necessitate a professional-grade scan tool.
What happens if I install it without doing the relearn procedures?
If a relearn procedure is needed and not performed, you may experience issues like an illuminated airbag warning light or improper brake light function. The core functions of the BCM will work, but for full system integration and safety, any required relearns should be completed.
Will this fix my ‘Security’ light and no-start problem?
A faulty BCM is a very common cause of Passlock security system issues in these GM vehicles, which often result in a flashing security light and an engine that cranks but won’t start. This VIN-programmed BCM is the correct solution for that problem.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module without any additional fees or hassle.
