Solution

1. Preparation

Gather necessary tools: screwdriver set, multimeter, fuse puller, and a panel removal tool.
Disconnect the negative terminal of the battery to ensure safety while working on the electrical system.

2. Inspect and Replace Fuse

Locate the fuse box (typically under the dashboard on the driver's side).
Remove the cover and locate the power window fuse.
Use a fuse puller to remove the fuse and check if it is blown (a broken metal strip indicates a blown fuse).
If the fuse is blown, replace it with a new one of the same amperage.

3. Test and Replace Relay

Locate the power window relay in the fuse box or relay box.
Remove the relay and check its functionality by swapping it with a similar relay from another circuit (if available).
If swapping does not resolve the issue, replace the relay with a new one.

4. Repair or Replace Window Switch

Remove the door panel using a panel removal tool to access the window switch assembly.
Disconnect the window switch harness and test with a multimeter for continuity.
If the switch is faulty, replace it with a new switch compatible with the RAV4.

5. Inspect Wiring Harness

Visually inspect the wiring harness for any signs of wear, fraying, or disconnection.
If damage is found, repair the wiring using appropriate electrical connectors or replace the entire harness if necessary.

6. Reassemble and Test

Reconnect the window switch harness and reassemble the door panel.
Reconnect the negative battery terminal.
Test all power windows to ensure they are functioning properly.
