2001-2010 PT Cruiser Rear Window Regulator: Wagon vs. Convertible & Motor Guide
Don't get stuck with the wrong part; learn the key differences between wagon and convertible regulators and why the motor connector matters.
- Regulators for 4-door Wagons and 2-door Convertibles are NOT interchangeable; this guide is for Wagons only.
- Failure is common and usually caused by snapped cables or broken plastic clips.
- Before buying a used part, verify if it includes the motor and that the electrical connector matches your vehicle's.
- Failure is not a direct safety risk, but it leaves the vehicle interior exposed to weather and theft.
Critical Compatibility Warning: Wagon vs. Convertible
Warning: The most important thing to know when buying this part is that rear window regulators for the 4-door Wagon and 2-door Convertible models are NOT interchangeable. The convertible has a completely different rear quarter window and regulator mechanism. All information in this guide applies ONLY to the 4-door Wagon models. Do not attempt to fit a wagon regulator into a convertible.
Symptoms of a Failing Rear Window Regulator
When a window regulator starts to fail, it usually gives one or more clear warning signs. The most common cause is the fraying and snapping of the internal steel cables or the breaking of plastic guide clips.
- Window Drops Into the Door: This is the most dramatic symptom. You may hear a loud pop or snap, followed by the glass sliding all the way down into the door shell. This indicates a complete failure, usually a snapped cable.
- Grinding, Clicking, or Popping Noises: Any unusual noises when operating the window are a bad sign. Grinding or clicking often means the cable is frayed and bunching up, or the motor gears are struggling.
- Crooked or Jammed Window: If the window tilts to one side as it moves or gets stuck partway up or down, it's often because a guide clip has broken or the regulator rails are bent. This prevents the glass from moving smoothly in its tracks.
- Slow or Erratic Movement: A window that moves much slower than it used to is a sign of a failing motor or excessive resistance in the regulator mechanism. Sometimes the window may work intermittently.
Known Issues, TSBs, and Recalls
There are no specific recalls or Technical Service Bulletins (TSBs) from Chrysler for the rear window regulators on the 2001-2010 PT Cruiser. However, the failure of the regulator assembly, particularly the cables and plastic components, is a widely known common issue. The wiring in the door hinge area can also become frayed over time from repeated opening and closing, which can mimic a failed motor or switch. There was a safety recall (NHTSA 07V-149) for some 2005-2006 models concerning the fixed rear quarter glass separating from the vehicle, but this does not involve the movable door window or its regulator.
Pro Tip: Before assuming the regulator or motor is bad, check the window switch itself. The switches in the center console are also known to fail and can produce similar symptoms, such as a window that will go down but not up.
Buying a Used PT Cruiser Rear Window Regulator: What to Check
A used OEM regulator can be a cost-effective and reliable replacement, but a thorough inspection is key. Here’s what to look for:
- Confirm It's for a Wagon: First and foremost, ensure the part is from a 4-door wagon, not a 2-door convertible. They are completely different.
- Inspect the Cables: Look closely at the steel cables. They should be taut and free of any fraying, kinks, or rust. A frayed cable is a regulator that's about to fail.
- Check the Plastic Clips: Examine the plastic clips that attach to the bottom of the window glass. Look for any cracks, stress marks, or signs of brittleness. These are a primary failure point.
- Motor Included or Not?: Clarify if the assembly includes the motor. If it does, you'll need to verify the electrical connector.
- Verify the Motor Connector: There may be variations in the motor's electrical connector over the 10-year production run. The initial prompt mentioned a 2-pin connector for later models. It is critical to compare the connector on the used part to your original one to ensure it will plug into your vehicle's wiring harness. If you plan to reuse your old motor, make sure the regulator you're buying has the correct mounting points.

Replacement Overview & Difficulty
Replacing the rear window regulator is a common DIY job for those with basic mechanical skills. The process involves removing the interior door panel, peeling back the weather shield, unbolting the window glass from the regulator, and then unbolting the regulator assembly itself. You will need tools like a 10mm socket, Torx bits, and a Phillips screwdriver. It's important to tape the window glass in the 'up' position to prevent it from falling while you work.
Frequently Asked Questions (FAQ)
Will this regulator fit my 2005 PT Cruiser Convertible?
No. This part is only for the 4-door wagon models. The rear quarter window on the convertible uses a completely different regulator that is not interchangeable.
Can I just replace the broken plastic clips instead of the whole regulator?
While some aftermarket companies sell repair kits with just the plastic clips, it's often not a permanent solution. If the clips broke due to age and brittleness, the cables are likely also worn and near the end of their service life. Replacing the entire assembly is usually the more reliable long-term repair.
Do I need to buy a new motor with the regulator?
Not always. If your window failed because of a snapped cable (you could still hear the motor running), you can often reuse your existing motor. However, if the window stopped working with no noise, or moves very slowly, the motor itself may be the problem. Many regulators are sold as a complete assembly with the motor, which can simplify installation.
What tools are required for this job?
You will typically need a set of screwdrivers (Phillips), Torx bits (T27 or T30 for door panel screws), a 10mm socket with a ratchet and extension, a panel removal tool to avoid scratching the door panel, and painter's tape to hold the window glass in place.
