my Toyota RAV4's windows won't go down, what could be the issue?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the vehicle's battery to ensure safety while working with electrical components.

2. Inspect and Replace Fuses

• Locate the fuse box, typically found under the dashboard or in the engine compartment.
• Identify the fuse associated with the power windows using the fuse diagram.
• Remove the fuse using a fuse puller and inspect for a break in the filament.
• Replace with a new fuse of the same amperage.

3. Check Window Switch

• Remove the door panel to access the window switch.
• Disconnect the switch connector and inspect for corrosion or damage.
• Use a multimeter to test continuity across the switch terminals when pressed.
• If faulty, replace the switch with a new one.

4. Inspect Wiring and Motor

• With the door panel removed, check the wiring harness leading to the window motor for signs of wear or disconnection.
• If no visible issues are found, connect the window motor directly to a power source to test its operation.
• If the motor does not operate, replace it with a new window motor.

5. Reassemble Components

• Reinstall the door panel securely, ensuring all clips and screws are properly fastened.
• Reconnect the vehicle's battery.
