The Toyota Avalon is known for its comfort and luxury features, and one of those features is the rear power sunshade. This retractable shade helps keep sunlight out of the cabin and adds a touch of privacy. However, some owners may want to disable the rear sunshade due to motor failure, rattling noises, or simply because they don’t use it. In this comprehensive guide, we’ll explain the reasons for disabling it, the tools required, step-by-step instructions, and alternative solutions.
Why Disable the Rear Sunshade?
Here are the most common reasons Avalon owners choose to disable the power rear sunshade:
- Motor Failure: The motor can wear out and cause clicking or grinding noises.
- Stuck Shade: Sometimes the sunshade won’t retract properly and blocks the rear window view.
- Noise: Loose parts can rattle while driving, especially on rough roads.
- Cost of Repair: Replacing the sunshade motor assembly can be expensive, often costing several hundred dollars.
- Preference: Some drivers prefer not to use it and simply want it out of the way.
Quick Picks: Useful Tools & Parts for Disabling the Rear Sunshade
- Plastic Trim Removal Tool Set – Helps remove panels without scratching interior surfaces.
- Magnetic Screwdriver & Bit Set – Perfect for removing screws behind the rear seat and panels.
- Digital Multimeter – Useful if you want to disable the sunshade electrically by pulling its fuse or connector.
Methods to Disable the Rear Sunshade
There are two main approaches to disabling the Avalon’s rear sunshade: electrical disconnection and mechanical removal. Which method you choose depends on whether you want to keep the unit in place or remove it entirely.
Method 1: Electrical Disconnection (Quick & Reversible)
This is the easiest way to disable the rear sunshade without removing it from the car.
- Turn off the ignition and disconnect the negative battery terminal to avoid electrical issues.
- Access the rear sunshade wiring harness. This is usually located behind the rear seat or under the rear deck trim.
- Unplug the connector that powers the sunshade motor.
- Reconnect the battery and test—your sunshade should now remain permanently retracted and won’t respond to the button.
- If you want to restore it in the future, simply plug the connector back in.
Method 2: Fuse Removal
Disabling via fuse is another simple method, but it may also disable other accessories depending on Toyota’s wiring layout.
- Locate the Avalon’s fuse box (usually under the dash or in the engine bay).
- Refer to the fuse diagram in the owner’s manual to identify the fuse for the “Rear Sunshade” or “Rear Power Shade.”
- Remove the fuse using a fuse puller or pliers.
- Test the system—the sunshade should no longer activate.
- If other systems stop working, you may need to reconnect the fuse and try Method 1 instead.
Method 3: Mechanical Removal (Permanent Solution)
If you don’t plan on ever using the sunshade again, mechanical removal is the most permanent fix.
- Fold down the rear seats to access the rear deck area.
- Use a trim removal tool to carefully detach the rear deck cover.
- Locate the sunshade assembly mounted behind the rear seats.
- Disconnect the wiring harness from the motor.
- Unbolt the sunshade assembly using the correct socket size.
- Remove the unit entirely and reassemble the rear deck cover.
- This eliminates both weight and the possibility of future rattles.
