Pro-Tip from a 20-Year Vet: Check Your Grounds First!
Before you condemn your computer, do yourself a favor and check the basics. On these GM trucks and vans, poor ground connections are notorious for causing bizarre electrical problems that mimic a bad PCM. Grab a wrench and check the main battery-to-chassis ground, the engine block-to-frame ground strap, and the grounds near the PCM itself. A few minutes spent cleaning and tightening these connections can save you a lot of time and money. If your grounds are solid and the problems persist, you can be confident that the 1999-2002 Savana 3500 PCM 16265035 is the component you need.
Frequently Asked Questions
What information do you need from me?
After you place your order, we will need your vehicle’s 17-digit Vehicle Identification Number (VIN). This is crucial for us to program the module correctly for your specific van.
Do I need to have the dealership program this part?
No. This module arrives pre-programmed and ready for installation. The only additional step is a simple security relearn procedure (often called a VATS or Passlock relearn) that you can do yourself in about 30 minutes with just the ignition key. We include instructions for this process.
Will this fix my specific check engine light codes?
This module will correct any codes that are caused by a faulty computer. If the code is for a failed sensor or a wiring issue, you will still need to repair that underlying problem. However, a new PCM often resolves persistent, unexplainable codes that remain after other parts have been replaced.
Is this a genuine OEM part?
Yes, this is a genuine OEM component that has been meticulously inspected and prepared for programming. We ensure it meets or exceeds original factory specifications for reliability and performance. This is the quality part your 1999-2002 Savana 3500 PCM 16265035 needs.
