Is Your Savana 2500 Plagued with Electrical Gremlins?
If you’re a Savana owner, you know it’s a workhorse. But when the Body Control Module (BCM) starts to fail, it can bring your entire operation to a halt with some of the most frustrating and bizarre electrical problems. Are you experiencing flickering interior or exterior lights, power windows and locks that have a mind of their own, a radio that won’t turn on, or a persistent ‘Service Theft System’ light on your dash? These aren’t random issues; they’re classic symptoms of a failing BCM.
From My 20+ Years of Experience: A contractor brought his 2011 Savana 2500 into my shop last month. The power locks were cycling on their own, the dome light wouldn’t turn off (draining the battery overnight), and the van would intermittently refuse to start. After checking the basics, we traced it to a BCM that had suffered internal corrosion. The cause? A common but often-overlooked leaky windshield cowl seal that allowed water to drip directly onto the module over time. Replacing the BCM and fixing the leak got his van back to being the reliable work tool he depends on.

Simple Installation Guide
Replacing the BCM on your Savana is a manageable job for a DIYer with basic tools. It’s typically located in the center dash area.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Access the Module: You will need to remove the necessary dash panels to gain access to the BCM. On most Savana and Express vans, this is in the center stack, often behind the radio or climate controls.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. Note their orientation. Then, unbolt the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in place and securely reconnect all electrical connectors.
- Reconnect Battery: Re-attach the negative battery terminal.
Important Final Steps After Installation
While the core programming is done, some security and safety systems require a final handshake procedure after installation. This is critical for full system operation.
- Airbag System (SRS): To clear the airbag warning light, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a capable diagnostic scan tool. This re-establishes the security link between the BCM and the airbag module.
- Brake Pedal Position Sensor: Some vehicles may require a brake pedal position sensor relearn or recalibration. This ensures the brake lights and stability control systems function correctly.
Note: If you are not equipped with a professional-grade scan tool, a qualified local mechanic can typically perform these final procedures for you.
