Restore Your Minivan’s Reliability and Performance
Is your 2005 Chevrolet Uplander experiencing frustrating issues like stalling, a persistent check engine light, or a complete no-start condition?

This genuine GM engine computer is the definitive fix, pre-programmed specifically for your vehicle to restore its original performance and dependability.

Frequently Asked Questions
Do I need to do any programming myself?
No. This is the biggest benefit of our service. We program the ECM to the VIN you provide during checkout. When you receive it, it’s ready to be installed without any need for special tools or a trip to the dealership.
Where is the ECM located on my 2005 Chevy Uplander?
The ECM is typically located in the engine compartment on the driver’s side (LH side), often near the battery or air filter housing.
What is a VIN and why do you need it?
The VIN (Vehicle Identification Number) is your car’s unique 17-digit serial number. It contains specific information about your vehicle’s engine, transmission, and factory options. We use it to load the exact correct software onto your 2005 Chevy Uplander ECM 12591279 for a perfect match.
Is this a new part?
No, this is a fully tested, genuine GM part that has been sourced from a salvaged vehicle. This allows us to provide a reliable and affordable solution for keeping your vehicle on the road.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of your old ECM, then yes, this part will resolve the issue. However, if the light is on due to other problems (like a bad sensor or wiring issue), those problems will still need to be addressed separately.
How do I provide my VIN?
After you complete your purchase, you will need to send us a message with your vehicle’s 17-digit VIN. We cannot program and ship your part until we receive this information.
