Restore Full Electrical Function to Your GM Vehicle
Is your GMC Savana, Chevy Express, or other GM vehicle plagued by strange electrical issues? Intermittent power windows, flickering lights, malfunctioning door locks, or a security system that has a mind of its own are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and unpredictable problems. This replacement BCM, part number 22820314, is the definitive solution to restore order and reliability to your vehicle’s essential functions.
Common Symptoms of a Failing BCM
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s highly likely your BCM is the culprit:
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ Interior dome lights, headlights, or taillights staying on, flickering, or failing to turn on.
- ✔ The vehicle’s security system engaging randomly or preventing the engine from starting.
- ✔ Keyless entry remote not working consistently.
- ✔ Unexplained battery drain that leaves you with a dead battery overnight.
- ✔ Warning lights on the instrument cluster related to systems the BCM controls.
- ✔ Inability for diagnostic scan tools to communicate with the module.
Expert Pro Tip
Expert Pro Tip
Before condemning your BCM, always perform a full battery and charging system test. A weak battery, failing alternator, or poor ground connection (especially the main chassis ground) can starve modules of voltage and mimic the symptoms of BCM failure. A quick check of these fundamentals can save you significant time and money.
The Plug-and-Play Solution: Programmed to Your VIN
Replacing a BCM isn’t just about swapping hardware. Traditionally, a new module requires a trip to the dealership for expensive and time-consuming programming with specialized equipment. We eliminate that hassle completely.

This ensures that when the part arrives, it’s ready for installation right out of the box, saving you hundreds of dollars and significant downtime.
Your Go-To Solution for a Savana 3500 Body Control Module

A fully functional Savana 3500 Body Control Module is critical for work-ready reliability, controlling everything from interior lighting to door locks. Don’t let a faulty module disrupt your workflow or compromise your vehicle’s security. This direct-fit replacement ensures all systems operate as the factory intended.
Installation and Post-Setup Information
Installation is straightforward for a DIY mechanic or any professional technician. After the new module is installed, some vehicles may require one or two simple relearn procedures to fully sync with other vehicle systems. Please note the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed. This is a security handshake between the new BCM and the airbag module and requires a professional-grade diagnostic tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and to satisfy the traction control system.
- No Core Charge: We do not require you to return your old, faulty module. There is no core charge associated with this purchase.
This Savana 3500 Body Control Module is the most efficient and cost-effective way to solve your vehicle’s electrical problems and get back on the road with confidence. The combination of a quality part and our expert programming service provides a complete, ready-to-install solution.
