Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your vehicle? Flickering lights, unresponsive power windows, or a security system that has a mind of its own are common signs of a failing Body Control Module (BCM). This vital component is the central nervous system for your vehicle’s body electronics. When it fails, it can cause a cascade of confusing and disruptive issues. This genuine quality GM BCM, interchangeable with part number 15263497, arrives pre-programmed to your vehicle’s specific VIN, ensuring a direct, plug-and-play solution without requiring a trip to the dealership for expensive programming.
From the Diagnostic Bay
We had a 2013 GMC Sierra roll in with what the owner called ‘a ghost.’ The horn would randomly blare, the interior lights would flicker while driving, and the HVAC blower was completely dead. After checking grounds and fuses, all signs pointed to the BCM. A quick scan confirmed multiple communication error codes. Instead of a lengthy and costly diagnostic and programming session at a dealer, we installed one of our VIN-programmed modules. In under 10 minutes, the ‘ghost’ was gone, and all systems were operating exactly as they should. This is the simple, effective fix for these complex problems.
Is Your 2013 Sierra Body Control Module Failing?
The BCM manages a wide array of functions, and its failure can manifest in numerous ways. If you’re experiencing any of the following issues, a faulty BCM is the likely culprit. Replacing it can restore your vehicle’s reliability and functionality, getting you back on the road with confidence.
Symptoms of a Bad BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ HVAC system malfunctions, such as a blower motor that won’t turn on or stays on.
- ✔ Erratic interior or exterior lights (flickering, staying on, or not working at all).
- ✔ Security system faults, including random alarm activation or starting issues.
- ✔ An illuminated airbag warning light, often with DTC B1001.
- ✔ Communication issues between various electronic modules, leading to multiple warning lights.
- ✔ Wipers that operate erratically or not at all.
The Plug-and-Play Advantage
Our key service is programming this module to your vehicle’s VIN before it ships. This critical step integrates the BCM with your truck’s existing systems, like the powertrain control module and anti-theft system, right out of the box. This saves you hundreds of dollars in dealership programming fees and eliminates the need for specialized scan tools for the initial setup. Installation is straightforward, typically located under the driver’s side dash. While the physical swap takes minutes, be aware of potential post-install procedures. If an airbag light appears, a professional scan tool is needed to perform the ‘Setup SDM Primary Key’ function. This is a simple sync procedure, not a full reprogramming. There’s no core charge, so you can keep your old part without hassle.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and HVAC controls.
Why is VIN programming necessary for this part?
VIN programming loads your vehicle’s specific software and security information onto the module. Without it, the BCM won’t communicate correctly with other computers in your truck, leading to system malfunctions or a no-start condition.
Can I install this 2013 Sierra Body Control Module myself?
Yes, the physical installation is simple for a DIYer, usually taking less than 15 minutes. However, be prepared that a post-install procedure like an ‘SDM key sync’ might be required if the airbag light comes on, which needs a professional-grade scan tool.
Will this fix an airbag light with code B1001?
A faulty BCM is a common cause of the B1001 code. Replacing the module often resolves the issue, but you will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a capable scan tool to clear the light after installation.
Is there a core charge for my old part?
No, we do not require you to send back your old BCM. There is no core charge associated with this purchase.
