how to troubleshoot the power windows not working in my Toyota Camry Seventh Generation (2012-2017)

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked safely and turned off.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Replace the Fuse

• Locate the fuse box, typically under the dashboard or in the engine compartment.
• Refer to the fuse diagram to identify the power window fuse.
• Remove the fuse using a fuse puller or pliers.
• Inspect the fuse for continuity; replace it with a new fuse of the same amperage if blown.

3. Inspect and Test the Window Switch

• Remove the door panel to access the window switch assembly.
• Disconnect the switch connector.
• Use a multimeter to test for continuity across the switch terminals while pressing the switch. Replace the switch if it is faulty.

4. Test the Relay

• Locate the power window relay in the fuse box.
• Remove the relay and test it using a multimeter or swap it with a similar relay to see if operation resumes.
• Replace the relay if it is found to be defective.

5. Check Wiring and Connections

• Visually inspect the wiring harness for any frayed or damaged wires.
• Ensure all connectors are securely attached.
• Repair or replace any damaged wiring as necessary.

6. Test Window Motors

• Remove the door panel to access the window motor.
• Disconnect the motor connector.
• Use jumper wires to connect the motor directly to the battery to test its operation.
• Replace the motor if it does not operate when powered directly.
