Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shock.
Tools Required: Screwdriver set, multimeter, socket set.

2. Inspect and Replace Fuses

Locate the fuse box, typically under the dashboard or in the engine compartment.
Remove the cover and identify the fuse associated with the power windows.
Use a fuse puller or needle-nose pliers to remove the fuse.
Inspect the fuse; if it is blown, replace it with a new fuse of the same amperage rating.
Reconnect the battery and test the power windows.

3. Test and Replace Power Window Switch

Remove the door panel using a screwdriver and trim removal tools.
Disconnect the power window switch connector.
Use a multimeter to test the switch for continuity.
If the switch is faulty, replace it with a new switch and reconnect the wiring.

4. Check and Replace Window Motor

If the switch is functional, test the window motor by applying direct battery power using jumper wires.
If the motor does not operate, it may need replacement.
To replace, disconnect the power connector and remove the motor mounting screws.
Install the new motor and connect it properly.

5. Inspect Wiring and Connectors

Check the wiring harness for any frays, breaks, or corrosion.
Repair or replace any damaged wiring or connectors.
Ensure all connections are secure and free of corrosion.
