Solution

1. Preparation

Gather tools: screwdriver set, multimeter, wire connectors, and electrical tape.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box beneath the dashboard or under the hood.
Remove the power window fuse using a fuse puller or pliers.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage (typically 30A).
Reconnect the battery and test the windows.

3. Repair or Replace Window Switch

If the fuse is intact, access the window switch assembly by removing the door panel.
Disconnect the wiring harness from the switch.
Test the switch with a multimeter for continuity.
If defective, replace the switch with a new one and reassemble the door panel.

4. Inspect and Replace Window Motor

If the switch is functioning, check the window motor.
Access the window motor by removing the door panel.
Disconnect the wiring harness from the motor and apply direct battery voltage to test.
If the motor does not operate, remove it by unscrewing the mounting bolts and replace it with a new motor.
Reassemble the door panel after installation.

5. Check and Repair Wiring

If the motor fails to respond, inspect the wiring loom for damage.
Repair any exposed wires using electrical connectors and tape.
Reconnect all components and test the window operation again.
