Expert Insight: The Critical Role of VIN Programming
Many don’t realize that on these 2004 GM vehicles, a replacement PCM must be programmed with your specific Vehicle Identification Number (VIN).

Simply installing a non-programmed or junkyard unit will result in a no-start condition. We handle this essential programming for you, ensuring the module communicates perfectly with your vehicle right out of the box. This is the key to a successful and stress-free repair.
