Restore Full Electrical Function to Your GM Truck or SUV
Is your GMC Sierra, Chevrolet Silverado, or Tahoe plagued by frustrating electrical problems? Flickering lights, unresponsive power windows, or a malfunctioning security system are common signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing issues. This genuine GM Body Control Module, interchangeable with part number 25835965, is the definitive solution. We pre-program it to your vehicle’s specific VIN, ensuring a seamless, plug-and-play installation without requiring a trip to the dealership for expensive programming.
Is Your 2013 Sierra 2500 BCM Failing?
A faulty Body Control Module can manifest in numerous ways. If you’re experiencing any of the following, a replacement is likely needed:
- ✔ Unresponsive or erratic power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off, or flicker randomly.
- ✔ Malfunctioning HVAC controls, including an inoperative blower fan or incorrect temperature blending.
- ✔ An active airbag warning light, often accompanied by DTC B1001.
- ✔ Security system issues, including false alarms or no-start conditions.
- ✔ Intermittent wiper operation or failure to park correctly.
- ✔ A variety of communication-related Diagnostic Trouble Codes (DTCs).
The Plug-and-Play Advantage: VIN Programming Included
Don’t settle for a generic module that requires additional calibration. We take the guesswork out of the repair by programming this module with the latest GM software updates specific to your vehicle’s VIN. This critical step ensures that all vehicle options and security protocols are correctly configured right out of the box. This not only guarantees optimal performance but also saves you hundreds of dollars in dealership programming fees.
Installation and Post-Install Notes
The BCM is typically located under the driver’s side dashboard, near the steering column. The physical replacement is straightforward and usually takes only a few minutes. However, please be aware of these potential post-installation procedures:
- Airbag System Sync: If the airbag warning light remains on after installation, a technician will need to use a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor relearn may be necessary to ensure correct brake light and traction control functionality.
Frequently Asked Questions
What exactly does the Body Control Module do?
