Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent electrical shorts.
Ensure a clean working environment.

2. Check and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the fuse for the power windows using a fuse puller.
Inspect the fuse; if it's blown, replace it with a new fuse of the same amperage (check owner's manual for specifications).

3. Inspect Window Switch

Remove the door panel using a socket set and trim removal tools.
Disconnect the wiring harness from the window switch.
Use a multimeter to test for continuity in the switch.
If the switch is faulty, replace it with a new one and reconnect the wiring harness.

4. Test Window Motor

If the switch is working, proceed to the window motor.
Disconnect the motor from the window regulator.
Use jumper wires to connect the motor directly to the battery to check if it operates.
If the motor does not work, replace it with a new motor.

5. Reassemble the Door Panel

Reconnect all wiring harnesses and ensure no wires are pinched.
Align the door panel and secure it with screws.
Reconnect the battery and test the power windows.
