Tired of Chasing Electrical Gremlins?
Are strange electrical problems in your GM truck or SUV driving you crazy? Power windows with a mind of their own, intermittent wipers, a security system that won’t cooperate, or random warning lights on your dash? These are classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s body electronics, a faulty BCM can create a cascade of frustrating, hard-to-diagnose issues. Stop guessing and replace the root of the problem with this reliable, direct-fit solution.
Common Symptoms & Your Direct-Fit Solution
If you’re experiencing any of the following, a failing BCM is the most likely culprit:
- Erratic power windows, door locks, or interior lights
- The security or anti-theft light stays on, preventing the engine from starting (PassLock issues)
- Wipers or radio turning on and off unexpectedly
- Warning lights appearing on the dash for no reason
- Inability for a scan tool to communicate with the module (DTC U1000)
This isn’t just a replacement part; it’s a complete, ready-to-install fix. We pre-program this Programmed 19208539 Body Control Module to your vehicle’s specific VIN, ensuring it communicates perfectly with all other systems right out of the box.

A Veteran Technician’s Tip
Many owners chase down individual switch and wiring problems for weeks, only to find the BCM was the root cause. A classic sign is when multiple, unrelated electrical components fail at the same time. Before you start tearing apart door panels, check for communication with the BCM using a capable scan tool. If it’s unresponsive or throwing communication codes (U-codes), you’ve likely found your culprit. This VIN-programmed unit saves you that diagnostic headache by providing a known-good, correctly configured starting point for your Programmed 19208539 Body Control Module installation. It’s the fix we’d perform in our own shop.
Frequently Asked Questions
Do I need to send you my old BCM?
No. This Body Control Module is sold without a core charge, so you can keep your original part. This saves you the time, cost, and hassle of shipping a core back.
Is this part truly plug-and-play?
Yes, for the vast majority of vehicles. Because we program the BCM to your VIN before shipping, it is ready to be installed and function. However, in some cases, you may need a professional scan tool for post-installation procedures like syncing the airbag system or performing a brake pedal position relearn, as noted in our documentation.
How do I provide my VIN for programming?
It’s simple. After you complete your purchase, please send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive the VIN, as the programming is a required step.
What happens if the airbag light comes on after installation?
If the airbag (SRS) warning light is on after installing the new BCM, it means the module needs to be synced with the vehicle’s airbag system. This requires a professional-grade scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a standard security step on these GM platforms.
Will this fix my ‘Security’ light issue?
BCM failure is a very common cause of PassLock security system problems that trigger the ‘Security’ light and a no-start condition. This Programmed 19208539 Body Control Module is correctly configured to your vehicle’s security information, resolving these issues and allowing your vehicle to start and run reliably.
How can I be sure this fits my vehicle?
Please review the detailed fitment list on this page. The most accurate way to ensure compatibility is to match the service number (e.g., 19208539, 9371990, or 9385236) from the sticker on your original BCM to the numbers listed in our description.
