Are you tired of chasing electrical gremlins in your 2000 GM truck? One day the power windows work, the next they don’t. The security light flashes randomly, or the interior lights have a mind of their own. As a technician with over two decades of experience, I’ve seen these exact frustrations countless times. The culprit is almost always a failing Body Control Module (BCM). This isn’t just a part; it’s the central command for your vehicle’s comfort and security features. We offer a reliable, direct-fit solution: a BCM programmed specifically to your truck’s VIN, ready for installation right out of the box.
This eliminates the biggest headache of BCM replacement—the expensive trip to the dealership for programming. Simply provide us with your VIN during checkout, and our experts will flash the module with the latest GM software updates for your specific vehicle. This ensures all factory-installed options work correctly from the moment you plug it in. This is the most efficient way to get your truck back to 100% without the hassle and high cost of traditional repairs. Get the right part, programmed correctly, the first time.
Case Study: A Tricky Diagnosis
I remember a 2000 Tahoe that came into my shop with a laundry list of bizarre symptoms: the radio would cut out, the driver’s side power lock was dead, and the dome light would flicker while driving. The owner had already replaced the battery and checked all the fuses. A scan showed a few communication (U-series) codes, which can be a real rabbit hole. Instead of chasing wires for hours, my experience pointed straight to the BCM. We swapped in a VIN-programmed module, and like magic, every single issue was resolved instantly. This is a classic failure pattern for these vehicles, and this 2000 Yukon BCM is the definitive fix.
Is Your Truck Showing These Symptoms?
A failing BCM can cause a wide range of issues that seem unrelated. If you’re experiencing any of the following, a faulty module is the likely cause:
- ✔ Erratic or non-functional power windows, mirrors, or door locks.
- ✔ The security or anti-theft light stays on or flashes, preventing the engine from starting.
- ✔ Interior or exterior lights that don’t work correctly (e.g., dome lights stay on, headlights flicker).
- ✔ Intermittent issues with the radio or climate control displays.
- ✔ Communication error codes (U-codes) stored in the vehicle’s computer system.
- ✔ False warnings on the driver information center (DIC).
A Straightforward Guide to Installation
This module is located under the driver’s side of the dashboard. While professional installation is always an option, a confident DIYer can complete this job with basic hand tools.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Access the Module: Remove the lower dash panel (kick panel) below the steering column to expose the BCM. It’s typically a black plastic box with several large electrical connectors.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. Then, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- Install the New BCM: Mount your new, pre-programmed 2000 Yukon BCM in the same location and securely plug in all the electrical connectors.
- Reconnect Power: Reconnect the negative battery terminal.
- Test Functionality: Start the vehicle and test all body functions—windows, locks, lights, radio, etc.—to ensure everything is working as it should.
Important Post-Installation Notes
In some cases, additional steps may be required after installation:
- Airbag System Sync: If the 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 airbag system with the new BCM.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration may be necessary on some models to ensure proper brake light and traction control operation.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does ‘programmed to my VIN’ mean?
It means we load your vehicle’s unique factory software and settings onto the BCM before shipping it. This makes the module plug-and-play, saving you a trip to the dealer for expensive programming.
Do I need to send my old BCM back?
No. This product has no core charge. You can keep your original module.
Will this fix my security light and no-start problem?
A faulty BCM is the most common cause of security system issues in these trucks. This module is designed to resolve those problems by restoring proper communication with the vehicle’s anti-theft system.
What if my airbag light comes on after I install it?
This can happen occasionally. It simply means the new BCM needs to be electronically introduced to the airbag module. A technician with a compatible scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and turn off the light.
This BCM has a different part number than my original. Will it work?
Yes. This module, part number 09377486, is the correct, updated replacement for several older part numbers, including 16257155 and 15136876. It is fully compatible.
