Restore Your Truck’s Electrical System with a Plug-and-Play BCM
Are you chasing electrical gremlins in your GM truck or van? Flickering lights, malfunctioning power windows and locks, a security light that won’t turn off, or strange messages on the dash are classic signs of a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and seemingly unrelated problems. This isn’t just an annoyance; it can affect vehicle security and safety systems. Stop guessing and replace the root cause with a reliable, pre-programmed solution.
This isn’t just a replacement part; it’s a complete fix. We flash this module with the latest official GM software updates specifically for your vehicle using the VIN you provide. This critical step ensures all your vehicle’s original features work correctly right out of the box, saving you a trip to the dealership and avoiding their expensive programming fees. Get your truck or van back to full functionality and reliability with a dependable GM BCM 15194169.
Case Study: A Tricky Diagnosis
A customer brought in his 2005 Silverado 2500 with a complaint that stumped two other shops: intermittent no-start and random power door lock cycling, even when parked. There were no engine codes, but the security light would flash occasionally. After checking the basics, I focused on the BCM. I’ve seen hundreds of these GMT800 trucks where water leaks from a degraded windshield cowl seal drip directly onto the BCM, causing internal corrosion. Sure enough, upon removal, we found tell-tale green corrosion on the pins. A new, programmed BCM fixed all the issues instantly. It’s a common failure point that many overlook, mistaking it for a bad starter or battery.
Is Your Truck or Van Showing These Symptoms?
- ✔ Power windows, mirrors, or door locks work intermittently or not at all.
- ✔ The security or anti-theft light stays on or flashes, preventing the engine from starting.
- ✔ Interior dome lights or dashboard lights flicker or stay on, draining the battery.
- ✔ The horn honks randomly or the alarm goes off without reason.
- ✔ You’re seeing communication error codes like U0140, U0155, or U0164 on a professional scan tool.
- ✔ The radio or instrument cluster behaves erratically.
Your Straightforward BCM Installation Guide
Replacing the BCM is a manageable job for a DIYer with basic tools. The most important part is that our pre-programming service handles the complicated software side for you. Follow these steps for a successful installation.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all modules to power down completely.
- Locate the BCM: On Silverado and Sierra pickups, the BCM is typically located under the driver’s side of the dashboard, near the steering column. On Express and Savana vans, it’s usually found behind the center dash panel.
- Remove Trim Panels: Carefully remove any plastic trim or panels necessary to access the BCM. These are usually held in with clips or a few screws.
- Disconnect and Remove: The BCM has several large multi-pin electrical connectors. Carefully press the release tabs and pull the connectors straight out. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the original location and securely reconnect all electrical connectors. You should hear a click as they lock into place.
- Post-Installation Steps: Reconnect the negative battery terminal. Start the vehicle and check for proper function of all body electronics. In some cases, a post-install procedure like an Airbag System Sync or Brake Pedal Position Relearn may be needed. See the information below for details.
Important Information After Installation
While our programming handles the majority of the setup, some vehicle systems may require a ‘handshake’ with the new BCM. This is normal and can often be done with a high-end scan tool.
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary to sync the systems. This requires a professional-grade diagnostic tool.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure correct brake light operation and traction control function.
- No Core Charge: You are not required to return your old BCM. This eliminates core charges and return shipping hassles.
Disclaimer: Vehicle systems and procedures can vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step.

Important Notes: Fitment for pickup models often excludes Crew Cab configurations and may depend on transmission type (MT vs. AT). For vans, fitment may exclude the commercial tradesman package. Always match your part number or contact us with your VIN to confirm compatibility. This GM BCM 15194169 is the correct solution for these specific applications.
Frequently Asked Questions
Do I need to do anything after I purchase?
Yes. After you place your order, you MUST send us your vehicle’s 17-digit VIN. We cannot program and ship your BCM without it. This ensures the module is correctly configured for your specific options.
Is this a simple plug-and-play installation?
For the most part, yes. Because we program the module to your VIN, you will not need a dealership to perform initial setup. However, as mentioned above, some vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor, which requires a capable scan tool.
What happens if I install it and my security light is still on?
The pre-programming of this GM BCM 15194169 handles the security information. If the light is still on, double-check all connector seatings. If the issue persists, there may be another fault in the vehicle’s security system, such as the ignition switch or wiring, that needs to be diagnosed.
Will this fix my power windows AND my weird radio issue?
Yes, it’s very likely. The BCM controls a wide range of electronic accessories. Issues that seem unrelated, like power windows, radio, and interior lighting, often all point back to a single failing BCM. Replacing it typically resolves all these symptoms at once.
What does ‘Classic Style’ mean for 2007 models?
In 2007, GM produced both the old body style (known as ‘Classic,’ with a creased door skin) and the new GMT900 body style. This part fits the 2007 ‘Classic’ models only, which are carry-overs from the 2006 design.
