how to troubleshoot Honda Accord 9th Generation (2013-2017) power window not working

Solution

1. Preparation

• Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, and a repair manual for specific torque specifications.
• Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Inspect and Replace the Fuse

• Locate the fuse box using the vehicle's manual.
• Identify the power window fuse and remove it using a fuse puller.
• Inspect the fuse for any signs of failure. If blown, replace it with a fuse of the same amperage.

3. Replace the Window Switch

• Remove the door panel using a screwdriver and trim removal tool to access the switch.
• Disconnect the electrical connector from the switch.
• Test the switch for continuity; if faulty, replace it with a new one.
• Reconnect the new switch and reassemble the door panel.

4. Test/Replace the Window Motor

• If the switch is functional, locate the window motor by removing the door panel.
• Disconnect the motor wiring harness.
• Test the motor directly by applying battery voltage from a separate power source.
• If the motor does not operate, replace it with a new window motor.

5. Inspect/Replace the Window Regulator

• If the motor is functional but the window does not move, check the window regulator.
• Remove the window from the regulator if necessary.
• Inspect the regulator for any signs of damage or binding.
• Replace the regulator if it is faulty.
