Is Your Rendezvous Running Rough? Let’s Get It Fixed.
If you’re dealing with a 2003-2005 Buick Rendezvous that’s suddenly developed a mind of its ownโstalling at lights, shifting erratically, or throwing a persistent Check Engine Light that no amount of part-swapping seems to fixโyou’re likely staring down a failing Powertrain Control Module (PCM). As the central computer for your engine and transmission, when the PCM starts to go, it can create a cascade of confusing and frustrating symptoms.
Over my 20+ years in the shop, I’ve seen these specific GM modules cause some real head-scratchers. The internal circuit boards can develop micro-fractures from years of heat cycles and vibration, leading to intermittent connections that are a nightmare to diagnose without experience.
A Technician’s Real-World Experience
“A customer’s 2004 Rendezvous came in last week with these exact symptoms. It had a hard start condition, a P0601 (Internal Control Module Memory Check Sum Error) code that would come and go, and the transmission would occasionally slam into gear. The owner had already replaced a couple of sensors with no luck. After verifying the power and ground circuits to the PCM were solidโa critical first stepโwe knew the module itself was the culprit. Swapping in a properly programmed unit like this one had the vehicle running perfectly in under 30 minutes. It’s a common failure point on these platforms.”
The Direct, Reliable Solution: Programmed and Ready to Install
This isn’t just a replacement part; it’s a complete solution. We are offering a genuine quality Powertrain Control Module, part number 89017735, that arrives at your doorstep programmed specifically for your vehicle. You don’t need to pay for expensive dealership programming or tow your vehicle anywhere. Just provide us with your Vehicle Identification Number (VIN) during checkout, and we’ll handle the rest.
We flash the module with the latest, most stable software updates directly from GM. These updates are crucial, as they often contain fixes for factory drivability issues, improve transmission shift points, and enhance overall performance and fuel efficiency that weren’t available when your Rendezvous first rolled off the line.
Key Benefits of This Programmed PCM
- โ Solves Common Failure Symptoms: Directly addresses issues like random stalling, no-start conditions, harsh shifting, poor fuel economy, and false sensor codes.
- โ VIN-Programmed for You: Arrives ready for installation with the latest GM software loaded for your specific vehicle. No extra programming needed.
- โ Simple Installation: Located in the left-hand (driver’s side) of the engine compartment, typically inside the air filter housing assembly. It’s a straightforward swap for any competent DIYer.
- โ Restores Communication: Fixes communication errors between the engine, transmission, and other vehicle modules, eliminating confusing dash warnings.
Installation Note: Security Relearn Procedure
After installing the new PCM, you will need to perform a simple security relearn procedure so the module recognizes your key. This typically involves turning the key to the ‘ON’ position for 10-12 minutes, then off, and repeating two more times. This allows the PCM to sync with your vehicle’s anti-theft system. It’s an easy process that requires no special tools.
