Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.
Tools Required: Screwdriver set, multimeter, wire stripper/crimper, torque wrench.

2. Inspect and Replace the Fuse

Locate the fuse box inside the vehicle (usually under the dashboard or near the driver's side kick panel).
Use the fuse puller to remove the power window fuse.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage.

3. Test and Replace the Power Window Switch

Remove the door panel using a screwdriver to access the window switch.
Disconnect the window switch connector.
Use a multimeter to test for continuity across the switch terminals when pressed.
If there is no continuity, replace the power window switch with a new one.
Reconnect the door panel after the replacement.

4. Check and Repair Wiring

Inspect the wiring harness running through the door for any signs of wear, fraying, or disconnection.
If damaged wires are found, strip the ends and use a wire stripper/crimper to reconnect or replace the wiring.
Ensure all connections are secure.

5. Test and Replace the Window Motor (if necessary)

If the previous steps do not resolve the issue, the window motor may need replacement.
Disconnect the motor from the window regulator.
Apply direct power from a battery to the motor terminals to test its operation.
If the motor does not operate, replace it with a new window motor.
Reassemble the door panel and reconnect the negative battery terminal.
