Restore Full Electrical Control to Your GM Vehicle
Are you battling a cascade of bizarre electrical issues in your Cadillac, Chevrolet, or GMC? From flickering lights and malfunctioning power windows to a car that refuses to start, a failing Body Control Module (BCM) can turn your driving experience into a nightmare. The BCM is the central command center for your vehicle’s body electronics, and when it falters, it creates chaos. This listing offers a straightforward, reliable solution: a replacement BCM, part number 13587704, that arrives at your door fully programmed and ready for installation.
Is Your BCM Failing? Common Symptoms
A faulty BCM can manifest in numerous ways, often seeming unrelated. If you’re experiencing several of the following issues, your BCM is the likely culprit:
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security system or keyless entry failing to work correctly, or the alarm sounding randomly.
- ✔ The vehicle failing to start, even with a good battery and starter (no-crank, no-start condition).
- ✔ Warning lights appearing on the dashboard for various systems (ABS, Airbag, Traction Control).
- ✔ Wipers, horn, or radio behaving unpredictably.
- ✔ Inaccurate readings on the instrument cluster gauges.

This process ensures that when you receive the part, it is truly plug-and-play. You can install it yourself or have your local mechanic do it, completely avoiding the need for expensive, specialized dealer tools.
Post-Installation Procedures
Because our programming service makes this a direct replacement, most vehicles will not require any additional steps. However, in some cases, certain systems may need to be re-synced. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control functionality.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine-related functions. This includes power windows, locks, lights, wipers, the security system, and the instrument cluster. It acts as a central hub for these electronic systems.
How does your cloning service work?
You send us your original BCM. Our technicians use specialized equipment to read the unique vehicle data stored on it—like the VIN, mileage, and key codes—and write that exact data onto the replacement module we provide. This makes the new module an identical match for your vehicle’s systems.
Is this better than buying a used BCM from a junkyard?
Absolutely. A used BCM from another vehicle is programmed for that specific car. It will not work correctly in yours and will require expensive dealership programming to sync it. Our service bypasses that entire problem, providing a part that is already matched to your car.
Will I need to have a dealer program this module?
No. The entire point of our service is to eliminate the need for dealer programming. The BCM you receive from us will be pre-programmed with your vehicle’s data and ready for installation right out of the box.
What if my original BCM is water damaged or won’t communicate?
In many cases, even with significant damage, we can still recover the necessary data. Please contact us before ordering if your module is severely damaged (e.g., fire, major water intrusion) so we can assess the likelihood of a successful data transfer.
How long does the entire process take?
Once we receive your original module, our programming service typically takes 1-2 business days. The total time will depend on the shipping speed you choose to send your module to us and the return shipping time.
