Restore Full Functionality to Your GMC Savana Van
Are you chasing electrical gremlins in your 2004-2007 GMC Savana 1500? Issues like unpredictable power windows, a dead HVAC blower, or a security light that won’t turn off are classic signs of a failing Body Control Module (BCM). The BCM is the electronic nerve center for your van’s comfort and convenience features. When it fails, it can make your daily workhorse feel unreliable. This replacement BCM, part number 15137394, is the definitive solution to restore your van’s electronics to perfect working order.
The biggest hurdle in replacing a BCM has always been the expensive and time-consuming trip to the dealership for programming. We eliminate that step entirely. By providing your vehicle’s VIN at checkout, we program the module specifically for your van. It arrives at your door ready for a true plug-and-play installation, pre-loaded with the latest GM software updates. This ensures all your van’s original features work just as they did from the factory, without any extra hassle.
A Technician’s Notebook
I recently had a 2006 Savana 2500 work van in my bay that was causing its owner major headaches. The complaint was intermittent no-start and the security light staying on. The owner, a plumber, had already replaced the battery and checked the ignition switch. After hooking up my scanner, I found a handful of communication codes, including the dreaded B1001. A quick check of the BCM’s data stream showed erratic voltage readings. This is a common failure point I’ve seen in hundreds of these GM vans and trucks. Instead of a costly diagnostic chase, we installed a VIN-programmed BCM. The van started right up, the security light went out, and all codes were cleared. The customer was back on the road to his next job in under an hour.
Is Your Savana Van Showing These Symptoms?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, a new module is likely the fix you need. This 2004-2007 Savana 1500 BCM is designed to resolve these exact problems.
- âś” The air conditioning or heater controls work intermittently or not at all.
- âś” Your power door locks or windows have a mind of their own.
- âś” The interior dome lights or exterior lights flicker or fail to turn on.
- âś” An airbag warning light is illuminated on the dash, often with a B1001 DTC.
- âś” The vehicle’s security system prevents it from starting (Passlock issues).
- âś” You’re getting a variety of communication or body-related trouble codes.
A Straightforward Guide to Installation
For the GMC Savana and Chevrolet Express vans, the BCM is conveniently located and easy to access, making this a perfect job for a DIYer or a quick swap for a professional mechanic.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system.
- Locate the BCM: On Savana and Express vans, the BCM is typically found in the center dash area, often accessible by removing a lower dash panel. It’s a black plastic box with several large multi-pin connectors.
- Swap the Module: Carefully unplug the electrical connectors from the old BCM. They have release tabs that need to be pressed. Unbolt or unclip the old module and remove it.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location. Firmly reconnect all the electrical harnesses. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reconnect the battery terminal. Start the vehicle and test all functions: lights, wipers, power locks, windows, and the HVAC system to confirm the repair.
Important Post-Installation Notes
While this module is programmed for plug-and-play functionality, some vehicle systems may require a ‘handshake’ with the new BCM. If your airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ may be needed on some models. There is no core charge for this part, so you can keep your old module without any extra steps.

Frequently Asked Questions
Do I need to take my van to the dealer after installing this BCM?
No. This module comes pre-programmed to your vehicle’s VIN. This means you can install it yourself and it will work immediately, saving you the time and expense of a dealership visit.
What is a core charge? Do I need to send my old part back?
A core charge is a deposit that is refunded when you return your old part. We do not have a core charge on this BCM, so you can keep your old part with no hassle.
Will this fix my airbag light?
It can. A faulty BCM is a common cause for an airbag light with DTC B1001. After installation, if the light remains, it simply means the new BCM needs to be synced with the airbag system (SDM), a quick procedure that can be done with a professional scan tool.
Is this BCM difficult to install?
Not at all. For a Savana or Express van, it’s located in the center dash and is one of the easier modules to replace. The entire process typically takes less than 30 minutes with basic hand tools.
What does ‘w/commercial tradesman package (opt PRP)’ mean for my van?
This refers to a specific factory option package (RPO code PRP) on Savana and Express vans. This BCM is the correct part for vans equipped with that package. If you are unsure, provide your VIN and we can verify compatibility for you.
