Fixing Power Windows That Won't Roll Up or Down in a Toyota Highlander XU70 (2020-Present)

Step 1: Check the Fuses

Tools Required: Fuse puller or needle-nose pliers, multimeter (optional).
Locate the Fuse Box:
- The fuse for the power windows is typically located in the cabin fuse box, which can be found under the dashboard on the driver's side.
- Refer to the owner's manual for the exact location and diagram of the fuse box.
Inspect the Fuses:
- Remove the fuse for the power windows (commonly labeled as 'P/W' or 'Power Window').
- Inspect the fuse for any signs of damage (broken filament).
- If using a multimeter, set it to continuity mode and check if the fuse is intact.
Replace the Fuse:
- If blown, replace it with a fuse of the same amperage.

Step 2: Inspect the Window Switch

Tools Required: Flathead screwdriver, multimeter.
Remove the Door Panel:
- Carefully pry off the door panel using a flathead screwdriver or a trim removal tool to access the window switch.
- Disconnect any electrical connectors to the door panel.
Test the Window Switch:
- Using a multimeter, check for continuity when pressing the switch.
- If the switch is faulty, replace it with a new OEM switch.

Step 3: Check the Window Motor

Tools Required: Socket set, screwdriver, multimeter.
Access the Window Motor:
- With the door panel removed, locate the window motor at the bottom of the door assembly.
Test the Motor:
- Disconnect the motor's electrical connector.
- Use a multimeter to check for voltage when the window switch is pressed.
- If there is no voltage at the connector, the issue may be upstream (wiring or switch).
- If voltage is present, the window motor may be defective.
Replace the Window Motor (if necessary):
- Remove the motor by unscrewing the bolts holding it in place.
- Disconnect the motor from the window regulator.
- Install the new motor in reverse order, ensuring it is properly aligned with the window regulator.

Step 4: Check Wiring and Connections

Tools Required: Wire strippers, electrical tape, multimeter.
Inspect Wiring:
- Check the wiring harness leading to the window switch and motor for any signs of wear, fraying, or disconnection.
- Repair any damaged wires by splicing in new wire and securely insulating with electrical tape.
Reconnect Everything:
- Once any repairs are made, reconnect all connectors and the door panel.

Repair Instructions

Reassemble the Door Panel

Reattach the Door Panel:
- Align the door panel with the door frame and press it into place, ensuring all clips are firmly seated.
- Reconnect any electrical connectors for locks or lights.
Test the Windows:
- Before fully securing the door panel, test the window operation to ensure it is functioning properly.
Secure the Panel:
- Replace all screws and any trim pieces removed during disassembly.

Final Checks

Recheck the operation of all windows to ensure everything is functioning as expected.
Make adjustments if necessary to window alignment or operation.

By following these steps, you should be able to diagnose and repair the power window issue in your Toyota Highlander XU70. If problems persist after these checks, consider seeking assistance from a professional technician for further diagnostics.
