End Your Truck’s Electrical Gremlins for Good
Are strange electrical issues plaguing your Silverado, Sierra, or Tahoe? One minute the A/C works, the next it doesn’t. The power locks have a mind of their own, and a persistent airbag light stays on your dash. These frustrating, intermittent problems often point to a single culprit: 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 unpredictable issues. Restore order and reliability with our pre-programmed BCM, the definitive, hassle-free solution to get your truck back to 100%.
Common Symptoms & Your Solution
A faulty BCM can manifest in numerous ways, making your vehicle unreliable and annoying to drive. If you’re experiencing any of the following, this module is the solution you need:
- Intermittent or total loss of HVAC and climate controls.
- Power windows, door locks, or interior/exterior lights not working correctly.
- An active airbag warning light, often with DTC B1001.
- Security system malfunctions that can lead to a no-start condition.
- Erratic wiper operation or other accessory failures.

Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and the HVAC (climate control) system.
Is this BCM truly plug-and-play?
Yes. We program the module to your vehicle’s VIN before shipping. This ensures it communicates correctly with your truck’s other systems upon installation, requiring no further programming for primary functions.
How do I know if my BCM is failing?
Common signs include multiple, unrelated electrical issues happening intermittently. For example, your radio, power locks, and interior lights might all act erratically. Diagnostic trouble codes related to body functions, like B1001, are also a strong indicator.
Will this fix my airbag light?
A bad BCM can cause the airbag light to come on. While this module will fix the root cause, the airbag system (SDM) may need to be re-synced with the new BCM using a professional scan tool to clear the light. This is a standard security procedure.
Do I need to send my old part back?
No. We do not require you to return your original module. There is no core charge or deposit associated with this purchase, making the process simpler for you.
What tools are needed for installation?
Installation is very straightforward. Typically, you will only need a basic socket or nut driver (often 7mm or 10mm) to remove the lower dash panel and the module’s mounting bolts. The entire process usually takes less than 10 minutes.
