Is Your Work Van Sidelined by Electrical Gremlins?
For a business owner or tradesperson, a GMC Savana 3500 isn’t just a vehicle—it’s an essential tool. When the Body Control Module (BCM) starts to fail, it can bring your operations to a halt with a cascade of frustrating and unpredictable electrical problems. One moment the A/C works, the next it doesn’t. The power locks have a mind of their own, and warning lights appear on the dash for no clear reason. This isn’t just an annoyance; it’s a threat to your schedule and your bottom line. Get your van back in service and working as hard as you do with this direct-fit, VIN-programmed BCM.

Frequently Asked Questions
What does a BCM do on my Savana 3500?
The Body Control Module acts as the central computer for your van’s non-engine related electronics. It manages functions like your interior and exterior lights, power windows, door locks, security system, wipers, and HVAC climate control system.
Is this BCM difficult to install?
For someone with basic mechanical skills, the installation is straightforward. The BCM is typically located in the center dash area on the Savana van. The process involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors. Since it’s pre-programmed, no computer work is needed.
Will I need to go to the dealer after installing this?
No. This BCM is delivered pre-programmed to your vehicle’s VIN. This key service bypasses the need for expensive dealership programming, making it a true plug-and-play solution.
What if my airbag light stays on after installation?
In some cases, the new BCM needs to be synced with the airbag system’s computer (SDM). If the airbag light remains on, a procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed using a professional-grade diagnostic scan tool. Most independent repair shops can perform this service.
How do I know this is the right part for my van?
This module is a direct replacement for part number 15136877 and several other interchangeable part numbers for 2004-2007 GMC Savana and Chevrolet Express vans with the commercial tradesman package (RPO code PRP). Always verify the part number from your original module or contact us with your VIN to confirm compatibility.
What does ‘no core charge’ mean?
It means you do not have to return your old, defective Body Control Module to us. This saves you the time, hassle, and expense of shipping the old part back, making your repair process simpler and faster.
