BCM interchangeable

Good afternoon,

If you are thinking of getting a used BCM, you will need the exact number on the module itself.

If you find one, then the used one needs to be flashed to your VIN number to work. Flashing a used BCM has about a 50-50 chance of working. Most dealers will not touch it unless it is a new one.

I attached the module from Rock Auto. The OEM GM numbers are there for you to match up.
