2004-2006 Scion xB Rear Window Regulator: Failure Signs and Replacement Guide
Learn to diagnose a failing rear window regulator in your first-gen Scion xB and what to look for when buying a used replacement.
- The most common failure is a snapped or frayed cable, causing the window to make grinding noises or drop into the door.
- This part (69803-52030) is only for the REAR RIGHT (passenger side) door on 2004-2006 Scion xB models with power windows.
- When buying a used regulator, carefully inspect the cables for fraying and the plastic clips/pulleys for cracks.
- Replacement is a DIY-friendly job, typically taking about an hour and a half with basic hand tools.
Symptoms of a Failing Window Regulator
When a window regulator in a 2004-2006 Scion xB begins to fail, it usually provides several warning signs. The issue is almost always mechanical wear on the regulator's cables or plastic parts, rather than a problem with the electric motor.
- Grinding, Clicking, or Scraping Noises: This is the most common early symptom. As the internal steel cables start to fray, or plastic pulley wheels break, you'll hear a distinct grinding or clicking sound when you operate the window.
- Window Drops Inside the Door: This indicates a complete failure. A cable has snapped or the clips holding the glass have broken, causing the window to fall suddenly and completely into the door panel. This may be accompanied by a loud snapping sound.
- Slow, Jerky, or Crooked Movement: If the window struggles to move, stutters on its way up or down, or tilts to one side, the regulator is binding. This puts extra strain on the motor and is a clear sign that the mechanism is worn out.
- Window Won't Stay Up: The window may slowly slide down on its own, either while driving or when parked. This means the regulator can no longer support the weight of the glass.
- Motor Runs, But Window Doesn't Move: If you can hear the motor whirring when you press the switch, but the glass stays put, the connection between the motor and the regulator is broken, or the regulator is completely detached from the glass. This confirms the regulator is the problem, not the switch or motor.
Compatibility Warning: This guide is for the rear right (passenger side) power window regulator, OEM part number 69803-52030. It will not fit the front doors, the rear left door, or models with manual crank windows. Always verify the specific door position before purchasing.
Known Issues, Recalls, and TSBs
For the 2004-2006 Scion xB, there are no specific recalls or Technical Service Bulletins (TSBs) for the window regulator itself. Failures are typically due to age and normal wear and tear on the cables and plastic components.
However, there is a significant safety recall for the driver's side master power window switch (NHTSA Campaign ID: 12V491000) that can affect window operation. This recall addresses a lack of lubricant in the switch, which can cause it to feel sticky, short circuit, and potentially overheat or melt. If you are experiencing erratic window behavior from the driver's controls, ensure this recall has been performed on your vehicle.
Buying a Used Window Regulator: What to Check
A used OEM window regulator can be a reliable and cost-effective alternative to a new part, often outlasting cheap aftermarket replacements. When inspecting a used part, pay close attention to the common failure points.
- Inspect the Cables: Carefully examine the steel cables. They should be taut and free of any fraying, kinks, or rust. Run your fingers along their length to feel for any broken strands.
- Check All Plastic Components: Look closely at the plastic pulleys the cables run on and the clips that attach to the window glass. These parts can become brittle with age. Reject any regulator with visible cracks, stress marks, or broken pieces.
- Verify the Electrical Connector: Make sure the electrical connector on the motor is intact and matches the one in your vehicle's door harness. Some aftermarket parts are sold with incorrect connectors.
- Confirm Part Number and Fitment: The OEM part number for the rear right regulator is 69803-52030. Ensure the part you are buying is from a 2004-2006 Scion xB and is for the correct door (rear passenger side).
Pro Tip: If possible, connect the used regulator's motor to a 12V power source before installation. Briefly applying power should make the motor run smoothly in both directions, confirming it works before you go through the trouble of installing it.

Frequently Asked Questions (FAQ)
My window dropped into the door. How can I secure it until I can fix it?
You will need to remove the door panel. Once inside, you can usually slide the glass up by hand. Use strong tape (like duct tape or packing tape) over the top of the door frame and onto both sides of the glass to hold it in the closed position. Alternatively, a small suction cup with a wedge can be used to prop it up from the inside.
Can I just replace the motor or the cables?
Generally, no. The window regulator and motor for the Scion xB are sold as a complete assembly. The failure is most often in the regulator's cables or plastic guides, not the motor itself. Attempting to repair the regulator assembly is not practical; replacement of the entire unit is the standard repair.
Does this part fit the front door or the driver's side?
No. Each door on the vehicle uses a unique window regulator. This part, 69803-52030, is specifically for the rear right (passenger side) door. You must purchase the correct part for the specific door you are repairing.
The window works from its own switch but not the driver's master switch. Is the regulator bad?
Unlikely. If the window operates correctly using the switch on its own door, the regulator and motor are working. The problem is almost certainly in the driver's side master switch panel or the wiring between it and the rear door. Check for the power window switch recall (NHTSA 12V491000) first.
