An Expert’s Note on VIN Programming
As a technician with over two decades of experience, I can’t stress this enough: VIN programming is not optional. Your Blazer S10 has specific settings for its engine, transmission, tire size, and emissions equipment. Simply installing a generic or junkyard PCM will, at best, result in poor performance and warning lights. At worst, it can prevent the vehicle from starting altogether due to anti-theft system conflicts. Our process ensures this 2005 Chevy Blazer S10 PCM 89017749 is a true clone of your original, but with the benefit of the latest factory software for peak reliability.
Frequently Asked Questions
Do I need to do any extra programming after I receive this?
No. This PCM is shipped fully programmed to the VIN you provide. In most cases, it is a simple plug-and-play installation. Some vehicles may require a security relearn procedure, which is a simple process that can be done without any special tools. We include instructions for this procedure.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information.
Where is the PCM located on a 2005 Chevy Blazer S10?
On the 2005 Blazer S10 and Jimmy S15, the Electronic Control Module (PCM) is typically located in the engine compartment, on the right-hand (passenger) side, often near the firewall or inner fender.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the PCM (common codes include P0601, P0602, P0606, U0100), then this part is the correct solution.
