Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We program the module to your vehicle’s VIN before it ships. This allows for a simple plug-and-play installation without any need for additional dealership programming.
Where is the BCM located on my 2013 Sierra 2500?
The Body Control Module is typically located under the driver’s side dashboard, near the steering column. Installation usually takes just a few minutes with basic tools.
What if my airbag light stays on after installation?
In some cases, particularly if you had an airbag-related code like B1001, a post-install procedure called ‘Setup SDM Primary Key in BCM’ is required. This must be done with a professional-grade scan tool but is a simple sync procedure that a qualified mechanic can perform.
Is there a core charge for this part?
No, there is no core charge. You can keep your old, non-working module without the hassle of returning it.
Will this fix my intermittent HVAC blower?
Yes, a faulty BCM is a very common cause of intermittent or non-working HVAC controls and blower motor operation. This module is designed to resolve those specific issues.
