Common Issues

The Toyota Avalon's rear sunshade is known to experience problems, particularly with retracting. Many owners report that the sunshade gets stuck in the up position and won't go down. This issue can be frustrating and potentially dangerous as it obstructs rear visibility, especially at night or in low-light conditions.

Causes of Malfunction

Several factors can contribute to the rear sunshade failure:

  • Worn-out plastic gear: Inside the sunshade motor assembly, there's a small plastic gear that can become brittle and fail due to heat exposure.
  • Motor failure: The electric motor responsible for raising and lowering the sunshade may stop functioning.
  • Control unit issues: Problems with the electronic control unit can prevent proper operation.
  • Mechanical binding: The sunshade mechanism might become misaligned or jammed.

Temporary Fixes

If your Avalon's rear sunshade is stuck, try these temporary solutions:

  • Manual assistance: Open both rear doors and gently push inward on the vertical sunshade bars while someone activates the sunshade button.
  • Lubrication: Apply a dry lubricant to the wheels connecting the vertical bars to the horizontal bar and into the tracks within the horizontal bar.
  • Fuse removal: Locate and remove the appropriate fuse (usually a 10A fuse) in the interior fuse box to stop the grinding noise and prevent further damage.

Long-Term Solutions

For a permanent fix, consider these options:

  • Replace the entire assembly: This is the most comprehensive but expensive solution, costing between $1,500 to $2,000 at a dealership.
  • Replace the motor/gear unit: A more cost-effective option is to replace just the faulty motor and gear assembly.
  • Install a metal gear: Some aftermarket suppliers offer metal replacement gears that are more durable than the original plastic ones.

Professional Repair

If you're not comfortable with DIY repairs, it's best to consult a professional mechanic. They can:

  • Properly diagnose the issue
  • Replace necessary components
  • Ensure the sunshade is correctly aligned and functioning

Preventive Measures

To avoid future problems:

  • Regular maintenance: Periodically lubricate the sunshade mechanism.
  • Gentle operation: Avoid forcing the sunshade if it meets resistance.
  • Limit usage: Consider using the sunshade only when necessary to reduce wear and tear.

When to Consider Disabling

If repairs are too costly or impractical, you might choose to disable the sunshade:

  • Remove the dedicated fuse (if applicable to your model)
  • Unplug the sunshade button harness
  • Have a mechanic remove the sunshade button and install a matching cover plate

Remember, a non-functioning sunshade is better than one stuck in the up position, which can significantly impair visibility.
