Have a failed, water-damaged, corrupted, or non-communicating GM Body Control Module (BCM)?

Lacorte Automotive offers a complete mail-in remanufactured BCM replacement service for supported Chevrolet, GMC, Cadillac, Buick, and other GM vehicles.

You send us your original BCM, and we provide a compatible remanufactured replacement BCM, transfer the applicable vehicle-specific data and configuration, professionally bench test the replacement, and ship everything back to you.

YOU SEND YOUR ORIGINAL BCM — WE PROVIDE THE REPLACEMENT

You do NOT need to purchase or send us a donor BCM.

We supply the compatible remanufactured replacement, and every BCM supplied through this service is backed by our 3-Year Warranty.

SUPPORTED GM BRANDS

Applications may include:

• Chevrolet
• GMC
• Cadillac
• Buick
• Pontiac
• Saturn
• Hummer
• Other supported GM applications

Compatibility depends on the vehicle year, platform, original BCM part number, hardware/software version, installed options, and vehicle configuration.

Not sure if we support your BCM? Send us a clear picture of the BCM label along with your VIN before ordering.

COMMON BCM FAILURE SYMPTOMS

A failing BCM may potentially cause:
