Restore Full Electrical Function to Your GM Truck or Van
Are you battling frustrating electrical gremlins in your vehicle? Issues like erratic power windows, door locks that have a mind of their own, a security light that won’t turn off, or interior lights that flicker or fail are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it malfunctions, it can cause a wide range of confusing and disruptive problems. This replacement module is the definitive solution to restore your vehicle’s functions to factory-perfect condition.
From the Diagnostic Bay
We had a 2005 Silverado in the shop where the owner had already replaced both power window motors, but the windows still wouldn’t work. He was convinced the wiring was bad. After a quick scan, we saw multiple communication codes pointing to the BCM. Instead of a costly and time-consuming wiring harness repair, the fix was a simple BCM replacement. A new, properly programmed module had his windows, locks, and lights working perfectly in under an hour. It’s a classic case of symptoms in one area being caused by the central computer.
Is a Failing BCM Causing Your Problems?
A faulty BCM can manifest in numerous ways. This replacement part is designed to correct these issues and get your truck or van operating reliably again. Check if you’re experiencing any of the following:
- ✔ Power windows, mirrors, or door locks operating intermittently or not at all.
- ✔ The security or anti-theft light stays on, potentially causing a no-start condition.
- ✔ Interior dome lights or dashboard lights flickering, staying on, or not working.
- ✔ The horn sounding unexpectedly or not working when pressed.
- ✔ False warnings on the instrument cluster (e.g., ‘door ajar’ light).
- ✔ Problems with the radio or climate control functions.

Important Post-Installation Steps
While this module is programmed for your vehicle, some systems may require a ‘handshake’ procedure after installation. This is a normal part of the repair process. Depending on your specific model, you may need a qualified technician with a professional scan tool to perform one of the following:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure correct brake light and traction control operation, a brake pedal position sensor recalibration may be necessary.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic accessories, such as power windows, locks, lights, security system, wipers, and more. It acts as a central hub for these functions.
Do I need to get this BCM programmed?
No. We handle the programming for you before shipping. Just provide us with your vehicle’s VIN during the checkout process, and the module will arrive ready to be installed and matched to your vehicle’s specific configuration.
Is this part difficult to install?
Installation is straightforward for those with basic mechanical skills. The BCM is typically located under the steering column or in the center dash area. It involves disconnecting the battery, removing a few trim panels, and swapping the module. However, some post-installation relearn procedures may require a professional scan tool.
Will this fix my ‘Service 4WD’ light?
While the BCM communicates with many systems, a ‘Service 4WD’ message is more often related to the Transfer Case Control Module (TCCM), encoder motor, or dash switch. It’s important to get a proper diagnosis to ensure you are replacing the correct part.
What is the core charge for this part?
There is no core charge for this Savana 3500 Body Control Module. You can keep your original part without needing to send it back.
