Restore Full Control Over Your Vehicle’s Electronics
Are you battling bizarre electrical issues in your Cadillac Escalade or GM truck? One moment the power windows work, the next they don’t. Maybe the A/C blower motor has a mind of its own, or a persistent airbag light is on your dash. These frustrating, hard-to-diagnose problems often point to one component: a failing Body Control Module (BCM). As the central hub for your vehicle’s comfort and security features, a faulty BCM can wreak havoc. This part, number 15136225, offers a definitive solution through our expert cloning service, getting you back on the road without a costly trip to the dealership.
Case Study: A Tricky Diagnosis
A customer brought in his 2005 Escalade with a laundry list of complaints: intermittent door lock failure, flickering interior lights, and the radio randomly shutting off. He’d already replaced the battery and checked all the fuses. In my 20+ years of experience, these ghost-like electrical problems scream BCM failure. We confirmed communication errors with a scan tool. Instead of a new, unprogrammed module that would require hours at a dealer, we recommended our cloning service. By transferring the data from his original BCM to a fully tested replacement, we created a true plug-and-play part. The install took him 10 minutes in his driveway, and all the strange electrical issues were gone for good.
Is Your Escalade Exhibiting These Electrical Gremlins?
A failing BCM doesn’t always cause a complete shutdown. It often starts with small, annoying glitches that can be easily misdiagnosed. If you’re noticing any of the following, your BCM is likely the culprit:
- ✔ Unresponsive or erratic power windows, door locks, or mirrors.
- ✔ HVAC system problems, such as the blower motor not working or being stuck on one speed.
- ✔ An active airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔ Malfunctioning security system, leading to no-start conditions or random alarm activation.
- ✔ Inconsistent operation of interior or exterior lights.
- ✔ A dashboard lit up with various unrelated warning lights.
The Advantage of Our Cloning Service for Your 2003-2006 Escalade BCM
This isn’t just a replacement part; it’s a complete, hassle-free solution. Our cloning service is the key to a simple and effective repair. Here’s what makes it the best choice for both DIYers and professional shops:
- ✔ True Plug-and-Play: We transfer the exact configuration and security data from your original module to the replacement unit. This means no additional programming or relearn procedures are needed at a dealership, saving you time and money.
- ✔ Guaranteed Compatibility: Cloning ensures the replacement BCM works perfectly with your vehicle’s specific options and existing electronic modules, like the engine computer and anti-theft system.
- ✔ Keep Your Original Keys: Since we copy your security information, your existing keys will work without any reprogramming.
- ✔ No Core Hassle: We always return your original module along with the cloned replacement. There are no core charges or deductions to worry about.
- ✔ Reliable Performance: Each module is thoroughly inspected and tested to meet or exceed OEM specifications, backed by our one-year warranty for your peace of mind.
Swap Your BCM in Minutes: A DIY Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On most 2003-2006 Escalade models and related GM trucks/SUVs, the BCM is located under the driver’s side dashboard, near the steering column.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once unplugged, the module can be unclipped or unbolted from its bracket.
- ✔ Install the New Module: Seat the cloned BCM into the mounting bracket and firmly reconnect all electrical connectors until they click into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all functions controlled by the BCM—lights, locks, windows, wipers, and HVAC—to confirm the repair was successful.

Frequently Asked Questions
Frequently Asked Questions
What exactly is a “cloning service?”
Cloning is a process where we read the critical software, security data, and vehicle-specific settings from your original BCM and write it directly onto the replacement module. This makes the new part an identical electronic twin to your old one, ensuring it works seamlessly with your vehicle without any further programming.
Will this fix my no-start problem?
If your no-start issue is caused by the BCM’s role in the vehicle’s anti-theft or security system (like Passlock or VATS), then yes, a properly cloned BCM will resolve it by restoring that communication link.
Do I need to send my original BCM to you?
Yes. For the cloning service to work, we need your original module to extract the data. We will return your original part along with the newly cloned replacement unit.
Is this part number 15136225 interchangeable with others?
Yes, this BCM is a direct replacement for several part numbers, including 15116066, 15198116, 10383536, and others listed in the product details. Our cloning service ensures compatibility regardless of the minor software variations between them.
What if an airbag light appears after installation?
This is uncommon but can happen. It means the BCM and the airbag system (SDM) need to be re-synced. This requires a professional-grade scan tool to perform the “Setup SDM Primary Key in BCM” function, a quick procedure for any qualified technician.
