Is Your Savana 1500 Running Rough or Not Starting at All?
If you’re dealing with a persistent check engine light, erratic engine behavior, stalling, or a complete no-start situation in your GMC Savana, a failing Powertrain Control Module (PCM) is often the culprit. As the brain of your vehicle’s engine, when the PCM goes bad, it can cause a host of frustrating and difficult-to-diagnose problems. You’re not just buying a part; you’re buying a solution to get your reliable workhorse back on the road.
This isn’t just another part pulled from a shelf. We provide a fully tested, reliable PCM that is pre-programmed specifically for your van. Simply provide us with your Vehicle Identification Number (VIN) after purchase, and our technicians will flash the module with the latest, most stable software updates directly from GM. This ensures perfect compatibility and optimal performance, right out of the box.
Expert Pro Tip: Check Before You Swap
In my 20+ years on the shop floor, I’ve seen countless PCMs replaced only for the new one to fail shortly after. Before installing your replacement module, take a moment to inspect the main electrical connectors for any signs of corrosion or moisture. On these Savana and Express vans, the PCM is located in the engine bay (left rear), and water intrusion from a bad cowl seal can seep down and damage the pins. Cleaning the connectors with a dedicated contact cleaner can prevent a repeat failure and ensure a solid connection.

Simple Plug-and-Play Installation Guide
You can get this job done with basic hand tools right in your driveway. Follow these steps for a smooth installation:
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 15 minutes for the system capacitors to discharge.
- Locate the PCM: On your 2005-2007 Savana 1500, the PCM is located in the engine compartment on the driver’s side, near the firewall.
- Disconnect the Connectors: Carefully unclip and remove the electrical wiring harness connectors from the old module. Inspect them for any damage or corrosion as mentioned in our pro tip.
- Remove the Old Module: Unbolt the old PCM from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed PCM onto the bracket and securely tighten the bolts.
- Reconnect Everything: Plug the wiring harness connectors firmly into the new module until they click into place. Reconnect the negative battery terminal.
- Final Steps: Your vehicle may need to complete a CASE (Crankshaft Angle Sensor Error) relearn procedure, which can often be done with a capable scan tool or by driving the vehicle under specific conditions. This is a normal final step for this repair.
