Restore Your Vehicle’s Electrical System with Confidence
Are you battling frustrating and unpredictable electrical problems in your GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, or an instrument cluster that seems to have a mind of its own often point directly to a failing Body Control Module (BCM). Don’t let these problems compromise your vehicle’s safety and functionality. This professionally programmed BCM is the definitive, hassle-free solution to get your car back in perfect working order.
Common Symptoms & Your Solution
A faulty BCM can cause a wide range of issues that can be difficult to diagnose. If you’re experiencing any of the following, this part is your answer:
- Erratic or non-functional interior/exterior lights
- Power windows, door locks, or mirrors not working correctly
- Intermittent no-start or security light issues
- Warning lights appearing on the dash for no reason
- Communication error codes (U-codes) stored in the system
Instead of buying a used module that requires an expensive trip to the dealer for programming, our unique 13578420 BCM Programming Service handles everything for you. We transfer the critical data from your original BCM directly to this replacement unit, making the installation process truly plug-and-play.

Expert Insight: Why Cloning is the Smart Choice
Many people are tempted to buy a used BCM from a junkyard to save money, but this often leads to more problems. A BCM from another vehicle will have the wrong VIN and security information, which can prevent your car from starting. It also won’t be configured for your car’s specific options (like sunroof, power seats, etc.). Our 13578420 BCM Programming Service eliminates all that guesswork and risk. By cloning your original data, we create a perfect electronic ‘twin’ of your old module, ensuring every function works exactly as it did from the factory.
Frequently Asked Questions
How does this mail-in programming service work?
It’s simple. After you complete your purchase, we will contact you with instructions to ship your original BCM to our facility. Once we receive it, our technicians will clone the data to the replacement module and ship it back to you, typically within 1-2 business days. The returned module is ready for plug-and-play installation.
Will I need to do any programming after I install it?
No, the module is pre-programmed for your vehicle. However, in some cases, certain post-install procedures may be necessary. For example, if you see an airbag light, a ‘Setup SDM Primary Key in BCM’ procedure may be needed. A brake pedal position relearn might also be required on some models. These are simple relearn procedures, not full programming.
What part numbers is this compatible with?
This module and service are a direct replacement for the following GM part numbers: 13577850, 13505326, 13500384, 13574844, 13504004, 13504494, and 13578420.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, we can still extract the necessary data for the cloning process. Please contact us before ordering if your original module is severely damaged by water or fire, or if it has no communication whatsoever with a diagnostic scan tool.
Is this a guaranteed fix for my vehicle’s problems?
This service provides a fully functional, correctly programmed BCM. It will resolve all issues directly caused by a faulty BCM. We highly recommend a proper diagnosis by a qualified technician to confirm the BCM is the root cause of your problems before ordering our 13578420 BCM Programming Service.
