Frequently Asked Questions
Do I need to have this BCM programmed by the dealer?
No. This Body Control Module comes pre-programmed to your vehicle’s VIN. It is ready for installation right out of the box, saving you the time and expense of a dealership visit.
Where is the BCM located on my 2013 GMC Sierra 2500?
