how to troubleshoot my Honda Accord 10th Generation (2018-2022) power window not working

Solution

1. Preparation

• Gather tools: multimeter, socket set, flathead screwdriver, Phillips screwdriver.
• Ensure the vehicle is parked safely and power is off. Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Fuse

• Locate the fuse box (usually under the dashboard or in the engine compartment).
• Remove the power window fuse (consult the owner's manual for specific fuse location).
• Inspect the fuse; if blown, replace it with a fuse of the same amperage.

3. Test and Replace Power Window Switch

• Remove the door panel using a flathead screwdriver and Phillips screwdriver.
• Disconnect the power window switch connector.
• Use a multimeter to check for continuity across the switch terminals.
• If there is no continuity, replace the switch with a new one.
• Reconnect the switch and carefully reinstall the door panel.

4. Inspect Wiring and Connections

• With the door panel removed, visually inspect the wiring harness for any signs of damage or wear.
• Check all connections to ensure they are secure. Repair or replace any damaged wiring.
• If necessary, use electrical tape to insulate any exposed wires.

5. Check and Replace Window Motor

• If the switch tests good and the wiring is intact, the window motor may be faulty.
• Disconnect the power window motor from the wiring harness.
• Use a multimeter to test for voltage at the motor connector when the switch is activated.
• If voltage is present but the motor does not operate, replace the window motor.
