Is Your GM Vehicle Acting Possessed?
Are you dealing with a frustrating array of electrical gremlins in your Cadillac, Chevy, or GMC? Flickering lights, power windows with a mind of their own, or a security system that randomly prevents your vehicle from starting are all classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it starts to fail, it can cause widespread and unpredictable problems. Don’t let a faulty module sideline your truck or SUV. This listing is for a replacement BCM, part number 13594692, that comes fully programmed with your vehicle’s original data, offering a simple and permanent fix.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security or anti-theft system light is illuminated, causing a no-start condition.
- ✔ Dashboard warning lights (like ABS or Airbag) appear for no reason.
- ✔ HVAC (heating and air conditioning) controls behave unpredictably.
- ✔ Key fobs stop working or work intermittently.
- ✔ False warnings appearing on the Driver Information Center (DIC).
From the Diagnostic Bay
We had a 2015 Chevy Tahoe come into the shop with a classic BCM failure case. The customer complained of a parasitic battery drain that left him stranded twice, and his interior dome lights would flicker randomly while driving. We checked the battery and alternator, which were fine. After tracing the circuits, we isolated the BCM as the source of the drain. Instead of sending him to the dealer for a new module and an expensive programming session, we used our cloning service. We transferred the data from his original, faulty BCM to one of our replacement units. He installed it in his driveway in under an hour, and the problems were gone instantly. No battery drain, no flickering lights, and no costly dealership visit.
The Simple, Plug-and-Play Solution for Your 2015 Escalade BCM
Dealerships will charge you for a new module, plus several hours of labor for installation and programming from scratch. Our service bypasses this entire ordeal. By cloning the data from your original BCM directly onto the replacement unit, we create a true plug-and-play part. The replacement module will have your vehicle’s exact VIN, mileage, and option configuration. This means no complicated relearning procedures, no key programming, and no need for specialized dealer tools. It’s the most efficient way to get your vehicle back to 100% functionality.

Post-Installation Notes
While our goal is a 100% plug-and-play experience, some GM vehicles may require minor post-installation steps. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure proper brake light and traction control function.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.
Frequently Asked Questions
What exactly is a Body Control Module (BCM)?
The BCM is a computer in your vehicle responsible for managing and controlling a wide range of electronic functions not related to the engine. This includes power windows, locks, lights, security system, wipers, and HVAC controls.
Why do I have to send you my original BCM?
Your original BCM contains critical vehicle-specific data, including the VIN, security information for your keys, and settings for all your vehicle’s options. By cloning this data, we make the replacement module a perfect match for your vehicle, eliminating the need for costly dealership programming.
Will I need to have my keys reprogrammed after installation?
No. Because we transfer all the original security data, the replacement BCM will recognize your existing keys just like the original one did. This is a major benefit of our cloning service.
How long does the entire process take?
Once we receive your original module, the data transfer service typically takes 1-2 business days. The total time will depend on shipping times to and from our facility. We will provide you with a return tracking number as soon as it ships.
Is this compatible with other part numbers?
Yes, this module is a direct replacement for several part numbers, including 13594692, 13594768, 13593214, 13580690, 13591519, and 13594769. It fits a wide range of GM trucks and SUVs.
