Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.
Ensure the work environment is safe and organized.

2. Inspect and Replace Fuses

Tools Required: Fuse puller or needle-nose pliers
Locate the fuse box under the dash and/or in the engine compartment.
Remove the power window fuse and inspect it for continuity.
If the fuse is blown, replace it with one of the same amperage (refer to the owner's manual for specifications).

3. Test and Replace Power Window Switch

Tools Required: Multimeter, screwdriver
Remove the panel surrounding the power window switch.
Disconnect the switch connector and use the multimeter to check for continuity.
If the switch fails the test, replace it with a new switch.

4. Inspect Wiring and Connectors

Tools Required: Visual inspection tools, multimeter
Inspect the wiring harness for frays, cuts, or disconnections, especially where the harness passes through the door.
Repair any damaged wiring or replace the harness if necessary.

5. Test and Replace Window Motor

Tools Required: Jumper wires, screwdriver
Disconnect the window motor from its connector.
Use jumper wires to connect the motor directly to the battery to check for operation.
If the motor does not work, replace it with a new window motor.

6. Reassemble and Test

Reconnect all connectors and reassemble the door panel.
Reconnect the negative battery terminal.
Test each power window to ensure proper functionality.
