Restore Your Vehicle’s Electrical System with Confidence
Are you battling a storm of frustrating electrical issues in your GM vehicle? Flickering dashboard lights, unresponsive power windows, erratic door locks, or a security system that has a mind of its own are all classic signs of a failing Body Control Module (BCM). These problems aren’t just annoying; they can compromise your vehicle’s safety and reliability. Stop chasing electrical gremlins and get the definitive, hassle-free solution that gets your vehicle back to perfect working order.
Common Symptoms & Your Solution
A failing BCM can manifest in numerous ways, often leaving drivers and even mechanics confused. If you’re experiencing any of the following, your BCM is the likely culprit:
- Interior or exterior lights not working correctly (staying on or not turning on)
- Power windows, locks, or mirrors behaving erratically or not at all
- The security system preventing the car from starting (anti-theft light)
- False warning lights appearing on the instrument cluster
- Communication errors with other vehicle modules (DTCs like U-codes)
Our professional cloning service for this Programmed 13578420 BCM is the most reliable way to solve these issues. We take all the critical, vehicle-specific dataโlike the VIN, mileage, and key informationโfrom your original BCM and transfer it directly to a replacement unit.

Expert Insight: Why Cloning is the Smart Choice
Many people consider buying a used BCM from a junkyard to save money, but this often leads to more problems. A used module is locked to the donor vehicle’s VIN and security information. Installing it will cause an immediate conflict, and your car won’t start. You would still need to have it professionally programmed, which can be difficult and costly. Our cloning service for the Programmed 13578420 BCM completely eliminates this risk. We make the replacement module an exact digital twin of your original, ensuring a seamless and successful repair every time.
Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide you with instructions to ship your original BCM to our facility. Once we receive it, our technicians will extract the unique data and flash it onto the replacement Programmed 13578420 BCM. We then ship the ready-to-install module back to you, typically within 1-2 business days of receiving your original.
Will I need to do any programming after installation?
No, the module arrives fully programmed for your specific vehicle. However, in some cases, minor relearn procedures may be necessary. For instance, if your airbag light is on, a “Setup SDM Primary Key in BCM” procedure might be needed. Similarly, a Brake Pedal Position Relearn may be required for proper brake light and traction control function. These are simple procedures for any professional scan tool.
