End the Frustration and Restore Your Envoy’s Performance
Is your GMC Envoy XUV, Trailblazer, or Rainier suddenly acting up? Unexplained stalling, harsh shifting, a persistent check engine light, or a complete no-start condition can be incredibly frustrating. These aren’t just annoyances; they’re signs that the very brain of your vehicle, the Powertrain Control Module (PCM), may be failing. Instead of guessing with expensive diagnostics or settling for a generic, unprogrammed unit, get the definitive, reliable solution designed to get you back on the road with confidence. This is a direct-replacement, professionally programmed 2004-2005 Envoy XUV PCM that arrives ready for installation.

An Expert’s Insight: Why These PCMs Fail
As a technician with over two decades of experience, I’ve seen countless GMT360 platform vehicles like the Envoy, Trailblazer, and Saab 9-7X. The P12 PCM in these trucks is generally robust, but its location on the driver’s side of the engine block exposes it to years of intense heat cycles and constant vibration. Over time, these factors can cause microscopic cracks in the internal solder joints on the circuit board, leading to intermittent connections and the unpredictable, frustrating symptoms you’re likely facing. Replacing it with a professionally prepared 2004-2005 Envoy XUV PCM like this one, which has been verified and programmed with fresh software, is the most reliable way to solve these deep-seated electronic issues for good.
Frequently Asked Questions
Do I need to do any programming myself?
No. This PCM arrives at your door fully programmed to the VIN you provide after purchase. In most cases, it is a direct 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 and takes about 30 minutes. Instructions are readily available online.
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 need this to load the correct, vehicle-specific software onto your module before we can ship it.
Where is the PCM located on my Envoy XUV?
On the GMC Envoy XUV and related platforms (Trailblazer, Rainier, etc.), the PCM is located on the driver’s side of the engine block, below the alternator. It is a silver metal box with three large electrical connectors.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original PCM (indicated by codes like P0601-P0606 or communication errors), then this part is the correct fix. However, if the light is on due to a faulty sensor or another component on the vehicle, you will still need to diagnose and repair that separate issue. This module will allow your vehicle’s diagnostic system to function correctly again.
My original part has a different number on it. Will this still work?
Yes. General Motors often uses multiple part numbers for the same component over its production life. This PCM, part number 19210065, is the correct service replacement for all the part numbers listed in the description, including 12573576, 12584593, and others. As long as your vehicle is listed, this is the correct computer.
