Are you battling strange and frustrating electrical issues in your Chevrolet Express or GMC Savana van? Intermittent warning lights, malfunctioning power windows and locks, or a security system that acts up on 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 wide range of unpredictable problems. This replacement BCM, part number 25892622, is the definitive solution to restore your van’s electrical systems to perfect working order.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, mirrors, or door locks working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ Unexplained warning lights on the dashboard, such as the airbag or service vehicle light.
- ✔ Radio or infotainment system randomly turning on or off.
- ✔ A vehicle that won’t start despite having a good battery and starter.
Solving the Problem with a VIN-Programmed Module
Don’t let a faulty BCM keep your vehicle off the road. This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle out of the repair by programming the module specifically for your vehicle using your VIN. This ensures that all the factory settings and options your van came with are correctly loaded into the new BCM. We install the latest software updates from GM, so you’re getting a component that’s not only fixed but also fully up-to-date. This service eliminates the need for expensive programming tools or a trip to the dealership.
Installation and Post-Install Procedures for your Express 3500 Body Control Module
Installation is straightforward for anyone with basic mechanical skills. However, after the new module is installed, your vehicle may require one or two simple relearn procedures to fully sync the new BCM with other vehicle systems. These are not always necessary but are good to be aware of:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be required to ensure your brake lights and traction control system function as they should.
This BCM is a direct replacement for a wide range of part numbers and fits many GM vehicles beyond the Express van. Please verify your part number or consult the detailed fitment list to ensure compatibility.
Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle all the programming for you before we ship the part. Simply provide us with your vehicle’s VIN during or after checkout, and it will arrive ready to install with the latest GM software.
What is a BCM and what does it control?
The Body Control Module (BCM) is a computer that manages many of your vehicle’s non-engine related functions. This includes power windows, door locks, interior and exterior lighting, the security system, and the wipers, among other things.
My original part number is different, but it’s on your list. Will this work?
Yes. GM often consolidates and supersedes part numbers. If your original part number is included in our compatibility list, this module is the correct, updated replacement for your vehicle.
What happens if my airbag light turns on after I install this?
This can happen occasionally. It means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag system (SDM). A mechanic with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is this a difficult part to replace myself?
For most DIY mechanics, it’s a manageable job. The BCM is typically located under the dash. The main challenge is access. The key benefit of our product is that the difficult programming step is already done for you.
Is there a core charge for this part?
No, there is no core charge. You can keep your old module without needing to send it back.
