Frequently Asked Questions
Do I need to do any programming or flashing myself?
Absolutely not. This is the main benefit of our service. We handle all the programming for you before the part is shipped. Once you receive it, you simply install it. In some cases, a security or crank relearn procedure may be needed, which can be done without a high-end scan tool.
How do I provide my VIN number?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. You can typically add it as a note during checkout or send it to us in a message referencing your order number. We cannot ship your part until we receive the VIN.
Is this a brand new part?
This is a quality, fully tested, and functional OEM module that has been meticulously inspected and prepared to meet or exceed original factory specifications. It is programmed with the latest software for your vehicle.
Will this fix my specific problem?
While this 2004-2005 Malibu PCM is the solution for a wide range of electronic and performance issues, we always recommend a proper diagnosis by a qualified mechanic. If your vehicle’s symptoms match those of a failed PCM and you have relevant trouble codes, this part is very likely the correct fix.
