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

Solution

1. Preparation

• Tools Required: Socket set, multimeter, OBD-II scanner, trim removal tool.
• Ensure the vehicle is parked on a flat surface and the ignition is off.
• Disconnect the negative battery terminal to prevent electrical shock.

2. Fuse Inspection and Replacement

• Locate the fuse box, typically found under the dashboard or in the engine bay.
• Identify the power window fuse using the diagram on the fuse box cover.
• Remove the fuse using pliers or a fuse puller; check for continuity.
• If blown, replace with a fuse of the same amperage (usually 30A).

3. Switch Testing and Replacement

• Remove the door panel using a trim removal tool to access the power window switch.
• Disconnect the switch connector and use a multimeter to test for continuity.
• If the switch is faulty, replace it with a new unit and reassemble the door panel.

4. Motor and Regulator Inspection

• With the door panel removed, test the power window motor by applying direct battery voltage to the motor terminals.
• If the motor does not operate, it may require replacement.
• Check the window regulator for any obstructions or wear; replace if damaged.

5. Wiring Inspection and Repair

• Inspect the wiring harness for any visible damage, fraying, or corrosion.
• Repair or replace any damaged wires using appropriate connectors and electrical tape.
• Secure all connections and reassemble the door panel, ensuring no wires are pinched.
