Solution

1. Preparation

Gather tools including a multimeter, socket set, flathead screwdriver, and Torx bits.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse with a fuse puller or pliers.
Inspect the fuse for breakage; replace it with a fuse of the same amperage if necessary.

3. Check and Replace Relay

Locate the power window relay in the fuse box.
Remove the relay from its socket and test it by swapping it with a similar relay (e.g., horn relay).
If windows operate with the swapped relay, replace the faulty relay with a new one.

4. Inspect Wiring and Connectors

Remove the door panel using a flathead screwdriver and Torx bits.
Check wiring harness for frays, breaks, or corrosion.
Clean and resecure any loose connectors, then reassemble the door panel.

5. Test and Replace Window Motor (if necessary)

With the door panel removed, locate the window motor.
Use a multimeter to test for voltage at the motor connector when the switch is activated.
If no voltage is present, the issue may lie with the switch or wiring.
If voltage is present but the motor does not operate, replace the window motor.
