Get Your Work Van Running Right: The No-Hassle PCM Solution
If your 2005-2007 GMC Savana 3500 is giving you headachesโstalling, shifting erratically, refusing to start, or flashing a constant Check Engine Lightโyou know how frustrating it can be. Every hour your van is down, you’re losing time and money. Often, the culprit behind these baffling issues is a failing Powertrain Control Module (PCM), the computer that serves as your vehicle’s brain.
From the Shop Floor: “A customer’s 2006 Savana 3500 work van came into my shop last month. It had an intermittent no-start and was throwing a U0100 (Lost Communication with ECM/PCM) code. The driver was stranded twice in one week. After confirming the wiring and grounds were solid, we pinpointed a failing PCM, likely from years of heat cycles in the engine bay. It’s a classic failure I’ve seen hundreds of times on these GM vans and trucks. A new, correctly programmed module is the only reliable fix.”

Expert Pro Tip: Ensure a Perfect Connection
Before you install your new PCM, take a moment to inspect the vehicle’s harness connectors. Over the years, dirt, oil, and moisture can build up on the pins, causing a poor connection that can mimic PCM failure. I always recommend using a can of quality electrical contact cleaner and a small nylon brush to gently scrub both the male and female pins. A clean, solid connection is critical for the new module to function correctly.
Simple Installation: Get Back on the Road in Under an Hour
Replacing the PCM on your Savana or Express van is a straightforward job you can do with basic hand tools. No complex procedures are requiredโjust swap the module and you’re done.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On most 2005-2007 Savana and Express vans, the PCM is located in the engine compartment, on the driver’s side (LH) towards the rear.
- Disconnect Connectors: Carefully unclip the wiring harness connectors from the old PCM. They have locking tabs that need to be released.
- Remove Old Module: Unbolt the old PCM from its mounting bracket and remove it from the vehicle.
- Install New Module: Mount your new, pre-programmed PCM, reconnect the wiring harnesses securely, and re-attach the negative battery terminal.
- Final Step: Start the engine. The vehicle will recognize the new module, and you’ll be ready to go.
