Is Your Truck Experiencing Electrical Chaos?
If you’re dealing with bizarre and frustrating electrical issues in your GMC or Chevy truckโlike flickering lights, power windows and locks with a mind of their own, or a security system that prevents your engine from startingโa failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics. When it fails, it can cause a cascade of seemingly unrelated problems, making your trusted truck feel unreliable. This is the simple, effective solution to get your vehicle back in perfect working order.
Common BCM Failure Symptoms & Your Direct-Fit Solution
A faulty BCM can manifest in numerous ways. You might be experiencing one or more of the following:
- Intermittent or non-functional power windows, door locks, or mirrors.
- Interior or exterior lights that flicker, stay on, or don’t work at all.
- Erratic gauge cluster behavior or warning lights that won’t turn off.
- A vehicle security system that activates randomly or causes a no-start condition.
- Communication error codes (U-codes) when scanned with a diagnostic tool.
This replacement module is the definitive fix for these issues. We take the guesswork and hassle out of the repair by pre-programming this unit to your vehicle’s specific VIN number. This means no expensive trips to the dealership for programming are required. This is a true plug-and-play solution designed to solve the problems caused by a faulty original BCM, specifically the 2000 Yukon XL 1500 Body Control Module 9371990.

From the Technician’s Bench: The “Central Nervous System”
Think of the BCM as the central nervous system for your truck’s cabin and body features. It doesn’t control the engine, but it manages almost everything else you interact with dailyโfrom the chime that reminds you to turn off your headlights to the power locks that keep you secure. Over 20+ years, the original capacitors and processors in these modules can degrade, leading to the unpredictable issues you’re seeing. Replacing the BCM is not just about fixing a single problem; it’s about restoring the entire electronic stability of your vehicle. A pre-programmed 2000 Yukon XL 1500 Body Control Module 9371990 is the most efficient way to do it right the first time.
Post-Installation Information
While this unit is designed to be plug-and-play, some vehicle systems may require a recalibration procedure after installation. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool must be used to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician if you are unsure about any post-installation steps for your specific vehicle. Our goal is to provide a reliable part and the information you need for a successful installation of your 2000 Yukon XL 1500 Body Control Module 9371990.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine. This includes power windows, door locks, interior/exterior lighting, the security system, and warning chimes.
Is this BCM really plug-and-play?
Yes, it is. We pre-program the module to your vehicle’s specific VIN before shipping. This eliminates the need for expensive and time-consuming programming at a dealership. In most cases, you simply install it and you’re done, though some vehicles may require a minor relearn procedure as noted above.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your BCM without it. You can typically find your VIN on the driver’s side dashboard (visible through the windshield) or on the driver’s side door jamb sticker.
Do I need to send my old BCM back?
No. This product has no core charge. You can keep, discard, or recycle your original module at your convenience, saving you the hassle and cost of a return shipment.
What if my airbag light comes on after installation?
This can happen because the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Will this fix my specific problem?
This module is a direct solution for failures within the BCM itself. While it resolves the vast majority of common electrical issues listed, we always recommend proper vehicle diagnostics to confirm the BCM is the source of your problem before ordering. This ensures you are purchasing the correct part for your repair.
