Restore Full Control Over Your Van’s Electronics
If you’re dealing with baffling electrical problems in your work van or family vehicle, the Body Control Module (BCM) is often the culprit. As the central command for your vehicle’s comfort and security features, a failing BCM can cause chaos. This replacement BCM, compatible with part number 10383536, is the definitive fix for your 2004-2007 Express 1500 BCM issues. We take the guesswork out of the repair with our professional cloning service, transferring your vehicle’s specific data to this unit for a true plug-and-play solution.
Case Study: A Tricky Diagnosis
A local contractor brought in his ’06 Express 2500, a workhorse with over 200,000 miles. The complaint was maddening: the interior lights would sometimes stay on, draining the battery overnight, and the power door locks worked intermittently. He’d already replaced the battery and checked all the fuses. After connecting my scanner, I saw no specific DTCs pointing directly to a lock actuator or switch. However, I noticed communication errors with the security system. In my 20+ years of experience, these ghost-like electrical issues almost always lead back to a failing BCM. The internal relays and circuits wear out, causing unpredictable behavior. We installed a cloned BCM, and the problems vanished instantly. He was back on the job site the next day without the worry of a dead battery.
Is Your GM Vehicle Showing These Symptoms?
- ✔ The A/C or heater blower motor works only on high speed or not at all.
- ✔ Your power windows, mirrors, or door locks have stopped responding.
- ✔ The anti-theft or security light is flashing, causing a no-start condition.
- ✔ An airbag warning light is illuminated, often with a DTC like B1001 (Option Configuration Error).
- ✔ Headlights, taillights, or interior dome lights behave erratically.
- ✔ Unexplained battery drain that leaves you stranded.
A Straightforward Guide to Installation
Replacing the BCM is a job most DIYers can handle in minutes. Our cloning service means you won’t need a high-end scan tool for programming.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On Express and Savana vans, the BCM is typically found in the center of the dash area. On trucks and SUVs, it’s usually under the driver’s side dash, near the steering column.
- Swap the Module: Carefully unplug the electrical connectors from your old BCM. They have locking tabs, so be gentle. Plug the connectors firmly into your new, cloned module.
- Reconnect and Test: Reconnect the battery terminal. Start the vehicle and test all functions: lights, locks, windows, wipers, and HVAC controls to confirm the repair was successful.
Important Post-Installation Note: In some cases, particularly if the airbag light was on, a procedure like ‘Setup SDM Primary Key in BCM’ may be needed with a diagnostic tool to sync the modules. This is a simple step for any professional mechanic if required. We also include your original module with the return shipment, as there is no core charge.

Frequently Asked Questions
What is a “cloning service”?
Cloning is a service where we transfer the essential vehicle-specific data (like VIN, mileage, and security information) from your original BCM to the replacement unit. This makes the new module a perfect electronic match for your vehicle, eliminating the need for costly dealership programming.
Will this fix my airbag light?
If the airbag light is caused by a faulty BCM or a communication error code like B1001, this module will likely solve the problem. After installation, the SRS system may need to be re-synced using a professional scan tool to clear the light.
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 provide clear shipping instructions after you place your order. We then ship both your original module and the newly cloned replacement back to you.
Is this part difficult to install myself?
Not at all. Physically swapping the module is very simple and usually takes less than 15 minutes with basic tools. It’s typically located under the dash and held in place by a few clips or bolts. Our cloning service handles the complicated software side of the job.
What if my original BCM is completely dead or missing?
If your original module is non-communicative or lost, we cannot perform the cloning service. In these situations, please contact us directly, as we may have other programming solutions available for your specific vehicle.
