Experiencing Bizarre Electrical Issues in Your GM Truck or SUV?
Is your 2015 Sierra 2500 acting possessed? Flickering lights, malfunctioning power windows, a security system that won’t cooperate, or worse—a vehicle that refuses to start? These frustrating and unpredictable symptoms often point to a single culprit: a failing Body Control Module (BCM). When this central computer falters, it can throw your vehicle’s entire electronic system into chaos, making it unreliable and unsafe. Don’t let electronic gremlins keep your truck off the road or the job site. This is the straightforward, professional solution you’ve been looking for.
Common Symptoms & Your Solution
A faulty BCM can manifest in numerous ways. If you’re noticing any of the following, it’s a strong indicator that your module needs attention:
- Erratic or non-functional interior and exterior lights
- Power windows, locks, or mirrors working intermittently or not at all
- Instrument cluster gauges behaving strangely or going dark
- Security system faults or key fob recognition issues
- HVAC (heating and air conditioning) control problems
- Communication error codes (U-codes) stored in the system
Our professional programming service for the Programmed 2015 Sierra 2500 BCM 13594764 is the definitive fix. We take the complex guesswork out of the equation. By cloning the essential data from your original BCM onto this fully tested replacement unit, we provide a true plug-and-play module. This process eliminates the need for an expensive trip to the dealership for programming, saving you significant time and money.
Expert Insight: The Problem with Junkyard Modules
As a veteran technician, I’ve seen countless vehicle owners try to save a few dollars by installing a used BCM from a salvage yard. This almost never ends well. A BCM is not a simple part; it’s coded specifically to your vehicle’s VIN, options, and security keys. A mismatched module can cause even more problems, from non-starting conditions to disabled features. Our cloning service bypasses all these risks by precisely replicating your truck’s original software, ensuring every function works exactly as it did from the factory.

Important Post-Installation Notes
In some cases, specific vehicle systems may require a ‘relearn’ procedure after the BCM is installed. These are straightforward tasks for any qualified technician with a professional scan tool:
- Airbag System Sync: If the airbag warning light is on, the ‘Setup SDM Primary Key in BCM’ procedure will be needed to sync the systems.
- Brake Pedal Position Relearn: A recalibration may be necessary to ensure proper brake light and traction control function.

Frequently Asked Questions
How does the mail-in programming service work?
After you place your order, we will email you a form and detailed instructions for shipping your original BCM to us. Once we receive it, our technicians will clone the data to the replacement unit and ship it back to you, typically within 1-2 business days. Tracking information will be provided.
What if my original BCM is completely dead or unreadable?
In most cases, even with significant internal damage, we can still extract the necessary data. If for some reason your module is completely unreadable, we will contact you to discuss options, which may include a full refund.
Is this really plug-and-play? Will I need a locksmith or dealer?
Yes, this is a true plug-and-play solution. Because we clone your original module’s key data and VIN, the vehicle will recognize the replacement BCM as its own. No additional programming or key syncing is required for engine start-up. Some minor relearn procedures, as noted above, may be needed for specific subsystems.
Where is the BCM located on my 2015 Sierra 2500?
On the 2015 Sierra 2500, the Body Control Module is typically located on the driver’s side, either under the steering column or on the LH firewall area. Please consult a service manual for your specific vehicle to confirm the exact location before removal.
Do I need to return my old BCM after I receive the new one?
No. There is no core charge for this part. You will need to ship your original BCM to us for the programming service, but you are not required to leave it with us. We will ship your original unit back upon request.
