Fix Your HUMMER’s Electrical Problems for Good
If your 2003-2007 HUMMER H2 is suffering from bizarre electrical issues like flickering lights, a dead instrument cluster, or power windows with a mind of their own, a failing Body Control Module (BCM) is the likely culprit. Instead of facing a costly and complicated trip to the dealership, our professional Cloning Service for the 15136225 HUMMER H2 BCM provides a simple, permanent solution. We transfer all the essential data from your original module to a fully functional replacement, making installation a true plug-and-play experience. Get back the reliability and functionality you expect from your H2.
Case Study: A Tricky Diagnosis
A customer brought in a 2006 H2 with a frustrating array of symptoms: the radio would cut out, the A/C blower worked intermittently, and the security light would stay on, sometimes preventing it from starting. They had already replaced the battery and checked the grounds. After connecting my scanner, I saw a handful of communication codes pointing to the BCM. These GM modules are notorious for internal solder joint failure after years of heat cycles. We performed our cloning service, and within an hour of the customer getting the module back, their H2 was running perfectly—no more gremlins. This service saved them hundreds in diagnostic fees and dealership programming costs.
Is Your HUMMER H2 Showing These Electrical Gremlins?
A faulty BCM can cause a wide range of issues that seem unrelated. Here are the most common signs that your module needs attention:
- ✔ Intermittent or non-working power windows, door locks, or interior lights.
- ✔ HVAC controls are unresponsive, or the blower motor works sporadically.
- ✔ The security system acts up, causing a no-start condition.
- ✔ An airbag warning light on the dash, often with a DTC like B1001 (Option Configuration Error).
- ✔ Erratic gauge behavior or a complete loss of the instrument cluster.
- ✔ Communication errors with other modules on the vehicle network.
Our Simple Cloning and Installation Process
Our service is designed to be as straightforward as possible for both DIY mechanics and professional shops. Here’s how it works:
- Step 1: Place Your Order. Purchase this cloning service and we’ll provide shipping instructions.
- Step 2: Ship Us Your Module. Carefully remove your original HUMMER H2 BCM and send it to us. It’s typically located on the left-hand side of the dash.
- Step 3: We Perform the Cloning. Our technicians will expertly transfer your vehicle’s unique data (VIN, key information, security settings) to the replacement module.
- Step 4: Reinstall and Drive. We ship both your original module and the ready-to-install replacement back to you. Simply disconnect the battery, plug in the new BCM, reconnect the battery, and you’re done. No dealer visit required.
Important Note: In some cases, post-installation procedures like an Airbag System Sync (‘Setup SDM Primary Key in BCM’) or a Brake Pedal Position Relearn may be needed if related warning lights appear. This requires a professional-grade scan tool. Always consult a service manual for vehicle-specific details.

Frequently Asked Questions
What exactly is a BCM cloning service?
Cloning is a process where we read all the critical vehicle-specific data—like the VIN, mileage, key codes, and security settings—from your original BCM and write it directly onto a replacement module. This makes the new module an exact digital copy of the old one, ensuring seamless integration with your vehicle.
Why is this better than just buying a used module?
A standard used module will have the data from the donor vehicle and will not work correctly in your H2 without expensive and complex dealership programming. Our cloning service bypasses this entirely, making the replacement module plug-and-play.
Do I get my original BCM back?
Yes. We always return your original module along with the newly cloned replacement unit. We do not require a core.
What if my airbag light comes on after installation?
This can happen occasionally. It means the new BCM needs to be synced with the airbag system’s Supplemental Deployment Module (SDM). A professional shop will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool to resolve this.
Is the replacement module new?
We use high-quality, fully tested OEM-grade modules for our cloning service to ensure long-lasting reliability and performance that meets or exceeds original specifications.
