Solution

1. Preparation

Gather tools and parts required.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the power window fuse and inspect for continuity using a multimeter.
If blown, replace with a fuse of the same amperage (check owner's manual for specification).

3. Test and Replace the Window Switch

Remove the door panel to access the window switch.
Disconnect the switch connector and test for continuity using a multimeter.
If defective, replace the switch with a new one (ensure it matches OEM specifications).

4. Inspect Wiring and Connections

Visually inspect the wiring harness for frays, breaks, or corrosion.
Clean any corroded connectors and ensure secure connections.
Repair or replace damaged wiring as necessary.

5. Test and Replace the Window Motor

If the switch is working but the window is still unresponsive, remove the motor.
Apply direct battery voltage to the motor to check functionality.
If the motor does not operate, replace it with a new motor (ensure it is compatible with the RAV4 XA50).
