my Toyota Corolla E140 (2006-2013) power windows won't go down

Solution

1. Preparation

• Gather tools: socket set, multimeter, flathead screwdriver, Phillips screwdriver, and a trim removal tool.
• Disconnect the battery to avoid electrical shorts.

2. Inspect and Replace the Fuse

• Locate the fuse box; refer to the owner's manual for the exact location.
• Remove the fuse related to the power windows using the fuse puller.
• Inspect the fuse for any signs of damage; replace if blown (use a fuse of the same amperage).

3. Access the Window Switch

• Use a trim removal tool to carefully pry off the panel covering the window switch.
• Remove the screws securing the switch using a Phillips screwdriver.
• Disconnect the wiring harness from the switch.

4. Test and Replace the Window Switch

• Use a multimeter to test the switch for continuity; if faulty, replace with a new switch.
• Reconnect the new switch to the wiring harness.

5. Access and Test the Window Motor

• Remove the door panel using a socket set and trim removal tool to expose the window motor.
• Check for any visible damage or loose connections.
• Test the motor directly by applying power from the battery; replace if the motor fails to operate.

6. Reassemble Components

• Reinstall the door panel and secure it with screws.
• Reattach the window switch panel.
