Solution

1. Preparation

Gather tools: flathead screwdriver, Phillips screwdriver, multimeter, socket set.
Disconnect the negative battery terminal to ensure safety.

2. Check and Replace Fuse

Locate the fuse box under the dashboard or in the engine compartment.
Remove the power window fuse using the fuse puller.
Inspect the fuse; if blown, replace it with a new fuse of the same amperage.
Reconnect the battery terminal and test the windows again.

3. Inspect and Replace the Window Switch

Remove the door panel using a flathead screwdriver and a Phillips screwdriver.
Disconnect the electrical connector from the window switch.
Use a multimeter to check for continuity in the switch.
If faulty, replace with a new switch.
Reassemble the door panel and reconnect the battery to test.

4. Test and Replace the Window Motor

If the switch is functional, access the window motor by removing the door panel.
Disconnect the motor’s electrical connector.
Use a multimeter to check for voltage at the motor when the switch is pressed.
If no voltage is present, the wiring may be damaged; repair or replace as needed.
If voltage is present but the motor does not operate, replace the window motor.

5. Inspect Window Regulator

If the window motor is functional, the issue may lie with the window regulator.
Inspect the regulator mechanism for any binding or damage.
If damaged, remove the regulator assembly and replace it with a new one.
Reassemble the door panel and reconnect the battery to test.
