Are strange electrical problems in your GM truck, van, or SUV driving you crazy? Flickering lights, unresponsive power windows, a security system with a mind of its own, or even a vehicle that refuses to start are classic signs of a failing Body Control Module (BCM). Don’t let these frustrating gremlins sideline your reliable vehicle. This is the direct, pre-programmed solution to restore full electrical functionality and get you back on the road with confidence.
Common Symptoms of a Failing BCM & Your Direct-Fit Solution
If you’re experiencing any of the following, a faulty BCM is the likely culprit:
- Power windows, door locks, or mirrors working intermittently or not at all.
- Interior or exterior lights staying on, flickering, or not turning on.
- The security or anti-theft system preventing the vehicle from starting.
- Erratic behavior from the instrument cluster gauges or warning lights.
- Diagnostic Trouble Codes (DTCs) related to communication errors (U-codes).

An Expert’s Note on BCM Replacement: From over 20 years of hands-on diagnostics, I’ve seen countless DIYers get stuck with a ‘new’ BCM that doesn’t work because it wasn’t programmed. A BCM is the central computer for your vehicle’s body electronics. Without the right programming specific to your VIN, it can’t correctly operate components like your power windows or fuel pump relay. By providing a programmed 2002-2004 S10 BCM that is ready to install, we’re not just selling a part; we’re delivering a finished repair, saving you the headache and expense of a dealership visit.
Installation is straightforward for those with mechanical experience. The BCM is typically located under the dash, either in the center or under the steering column. Once installed, some vehicles may require a simple relearn procedure for certain systems, which we’ve detailed below. This programmed 2002-2004 S10 BCM is the most reliable way to restore your vehicle’s essential functions.
Frequently Asked Questions
Do I have to provide my VIN?
Yes. Providing your 17-digit Vehicle Identification Number (VIN) is mandatory. We use it to load the exact, correct software from GM for your vehicle’s specific features and options. This ensures the module works correctly right out of the box.
Is this part difficult to install?
For a moderately skilled DIYer, installation is manageable. The BCM is usually located under the dashboard. The primary challenge is accessing it. Once you locate it, it’s a matter of disconnecting the battery, unplugging the electrical connectors, swapping the module, and reconnecting everything. No special programming tools are required on your end.
What if my airbag light comes on after installation?
In some cases, the new BCM may need to be synced with the airbag system’s computer (SDM). If the airbag light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a quick process for any qualified repair shop.
Will this fix my intermittent no-start problem?
A failing BCM is a very common cause of no-start issues related to the anti-theft or security system (Passlock/VATS). If your security light is flashing and the vehicle won’t crank, this module is very likely the solution, as it comes programmed to work with your existing keys.
Is there a core charge for my old part?
No. We do not require you to return your old BCM. There is no core charge associated with this purchase, which simplifies the process for you.
What does ‘plug and play’ mean for this module?
It means we handle the difficult dealer-level programming before we ship the part to you. For the vast majority of vehicles, you can simply install the module, and it will function immediately without any further programming required. In some rare cases, minor relearn procedures as noted in our documentation may be necessary.
