Are you battling frustrating electrical gremlins in your GM truck or van? Intermittent wipers, flickering lights, malfunctioning power windows, or a security system that has a mind of its own are all classic signs of a failing Body Control Module (BCM). This vital component acts as the central hub for your vehicle’s body electronics. When it fails, it can cause a cascade of confusing and unpredictable issues. Get back on the road with confidence with this direct-fit, VIN-programmed BCM.

Expert Pro Tip
Before condemning your BCM, always perform a thorough check of your vehicle’s battery, alternator, and primary ground connections (especially the main chassis and engine block grounds). A weak battery or a poor ground can cause low voltage conditions that mimic the symptoms of a faulty BCM, potentially saving you from an unnecessary repair.
Common Symptoms of a Failing GM BCM
- ✔ Erratic or non-functional interior/exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security or anti-theft system preventing the vehicle from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers turning on by themselves or not responding to the switch.
- ✔ False warning lights appearing on the instrument cluster.

Installation and Post-Install Notes
Installation is typically straightforward, involving locating the old module (often under the dash or steering column), disconnecting the battery, swapping the electrical connectors, and mounting the new unit. However, on some models, additional steps may be required:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration may be necessary on certain models to ensure proper brake light and traction control functionality.
