Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse associated with the power windows using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers and inspect it for continuity.
If blown, replace it with a fuse of the same amperage rating.

3. Inspect and Replace the Window Switch

Use a screwdriver to remove the panel covering the power window switch.
Disconnect the switch from the wiring harness.
Test the switch with a multimeter for continuity. If defective, replace it with a new switch.
Reconnect the new switch and secure the panel back in place.

4. Test and Replace the Window Motor

Remove the interior door panel to access the window motor.
Disconnect the motor’s wiring harness.
Use a multimeter to check for voltage at the motor connector when pressing the window switch.
If voltage is present but the motor does not operate, remove the motor and replace it with a new one.
Reinstall the door panel and ensure all connections are secure.

5. Verify Wiring and Connections

Inspect wiring harnesses and connectors for damage or corrosion.
Repair or replace any damaged wiring as necessary.
Reconnect all connectors securely.
