Is Your GM Truck or Van Plagued by Bizarre Electrical Problems?
Are flickering dash lights, unpredictable power windows, or a faulty security system making you lose faith in your trusty GM vehicle? A failing Body Control Module (BCM) is often the culprit behind this chaos, disrupting the communication between your vehicle’s essential electronic components. This isn’t just an annoyance; it can affect vehicle security and functionality. We offer a reliable, straightforward solution: a replacement BCM, professionally programmed to your vehicle’s specific VIN, ready to restore order and dependability.
Common Symptoms & Your Solution
If you’re experiencing any of the following issues, a faulty BCM is the likely cause:
- Power windows, door locks, or mirrors working intermittently or not at all.
- Interior or exterior lights staying on, flickering, or not turning on.
- The security system engaging randomly or preventing the engine from starting (Passlock issues).
- Erratic gauge behavior or warning lights on the instrument cluster.
- Radio or climate control malfunctions.

Expert Insight: The GM Security System Handshake
Many of these early 2000s GM vehicles use a Passlock security system that is deeply integrated with the BCM. Simply installing a non-programmed or used BCM from another vehicle will almost always result in a no-start condition. The BCM, ECU, and ignition components must recognize each other through a specific ‘handshake’ programmed via the VIN. By pre-programming this GM 15063578 BCM, we perform that critical handshake for you, ensuring the module is accepted by your vehicle’s security system, allowing for a smooth installation and immediate start-up.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the central hub or computer for your vehicle’s body electronics. It controls non-engine-related functions like power windows, locks, interior and exterior lighting, the security system, wipers, and more. When it fails, these systems can behave erratically.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as the programming is essential for the part to function in your vehicle.
Is this a difficult part to install?
For someone with basic mechanical skills, the installation is typically straightforward. The BCM is usually located under the dash on the driver’s or passenger’s side. It involves disconnecting the battery, removing a few trim panels, and unplugging the electrical connectors. However, if you are not comfortable working on your vehicle’s electrical systems, we recommend professional installation.
Will I need to perform any procedures after installation?
In some cases, yes. As noted, if your airbag light comes on, a ‘Setup SDM Primary Key’ procedure may be needed. Additionally, a ‘Brake Pedal Position Relearn’ might be required. These are simple procedures for any shop with a professional-grade scan tool.
Can I use a BCM from a junkyard?
We strongly advise against it. A used BCM is programmed to a different vehicle’s VIN and options. Installing it in your vehicle will cause compatibility issues, security system lockouts (no-start), and incorrect operation of features. Our pre-programmed GM 15063578 BCM is the only way to guarantee correct functionality without dealership intervention.
