Restore Full Electronic Functionality to Your GM Vehicle
Is your Chevrolet, GMC, or Cadillac exhibiting strange and unpredictable electrical behavior? From flickering lights and malfunctioning power windows to random security alerts, these issues often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating problems. This replacement GM Body Control Module 13594764, complete with our expert programming service, is the definitive solution to restore your vehicle’s performance and reliability without the exorbitant costs and complexities of dealership repairs.
From the Diagnostic Bay
We recently had a 2015 Sierra 1500 in the shop that was driving its owner crazy. The horn would honk randomly, the interior lights wouldn’t turn off, and the instrument cluster would intermittently go dark. The owner had already replaced the battery and checked every fuse with no success. A diagnostic scan revealed a flood of communication errors all pointing back to the BCM. Instead of a new module and a lengthy, expensive programming session at the dealer, we provided a BCM cloned from the original. After a straightforward installation, every single electrical gremlin was gone. The truck was back to its reliable self, saving the customer significant time and money.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ False security system alarms or the inability to start the vehicle due to a security fault.
- ✔ Instrument cluster gauges behaving erratically or warning lights appearing without cause.
- ✔ Malfunctioning radio, climate controls, or other interior accessories.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss with other modules (U-codes).
The Simple, Plug-and-Play Solution
Our service is designed to be as straightforward as possible. You send us your vehicle’s original BCM. We then perform a professional data transfer, cloning all the essential vehicle-specific information—including VIN, mileage, and security keys—onto this replacement unit. The module you receive back is a true plug-and-play component, completely synchronized to your vehicle’s systems. This process bypasses the need for any additional on-vehicle programming with expensive scan tools, making the repair accessible for both professional technicians and capable DIY enthusiasts.
Your Replacement GM Body Control Module 13594764
This module is a direct replacement for several part numbers, ensuring wide compatibility across numerous 2015-2016 GM trucks, SUVs, and sedans. By matching part numbers 13592137, 13506935, 13506936, 13587704, or 13594764, you can be confident in a perfect fit and restored function for vehicles like the Silverado, Sierra, Tahoe, Suburban, Escalade, Corvette, and many more. Our cloning service makes this a superior alternative to buying a blank module that would require dealer intervention.
Post-Installation Procedures
While our programming makes this a plug-and-play installation, some GM vehicles may require simple recalibration procedures to ensure all systems communicate perfectly. These are typically straightforward and can sometimes be required after any battery disconnect or module replacement.
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This indicates a sync mismatch between the new BCM and the airbag system’s SDM. A ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool to resolve this. This is only necessary if the light is on.
- Brake Pedal Position Relearn: To ensure accurate brake light operation and stability control performance, a brake pedal position sensor recalibration might be necessary. This procedure helps the system recognize the pedal’s resting and applied positions.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.
Frequently Asked Questions
How does this programming service work?
After you place your order, we will provide you with instructions to ship your original BCM to us. Once we receive it, our technicians will transfer all the critical data to the replacement module. We then ship the ready-to-install BCM back to you, typically within 1-2 business days.
Will I need to do any additional programming after installation?
No. Our cloning service makes this a true plug-and-play module. It arrives pre-programmed with your vehicle’s specific data, so you will not need to visit a dealer or mechanic for programming. Some minor relearn procedures, like for the airbag or brake pedal sensor, may be necessary in certain vehicles.
What part numbers does this BCM replace?
This module is a direct replacement for part numbers 13592137, 13506935, 13506936, 13587704, and 13594764. Please verify one of these numbers on your original module to ensure compatibility.
Is there a core charge?
No, there is no core charge. We require your original module to perform the data cloning service, after which you do not need to send anything else back.
What if my original BCM is not communicating?
In most cases, even if the BCM is malfunctioning, we can still extract the necessary data. If your module has severe water or fire damage, please contact us before ordering to discuss options.
