Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.
Tools Required: Multimeter, socket set, flathead screwdriver, Torx screwdriver.

2. Check and Replace Fuses

Locate the fuse box (usually found under the dashboard or in the engine compartment).
Identify the fuse for the power windows (refer to the owner’s manual for the specific fuse location).
Use a multimeter to check for continuity in the fuse.
If the fuse is blown, replace it with a new one of the same amperage.

3. Inspect and Repair Wiring

Remove door panels carefully using a flathead screwdriver or Torx screwdriver.
Visually inspect the wiring harness for frayed wires or broken connections.
Repair any damaged wires by soldering or using heat-shrink connectors.
Ensure all connectors are securely fastened.

4. Test Window Motors

Disconnect the window motor connector.
Using a multimeter, check for voltage at the connector while operating the switch.
If voltage is present but the motor does not operate, replace the motor.
If no voltage is present, trace the wiring back to the switch or control module for further inspection.

5. Reassemble and Test

Reattach the door panels securely after repairs are completed.
Reconnect the battery.
Operate the window switches to confirm functionality.
