Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative terminal of the battery to prevent any electrical shock or short circuit.

2. Inspect and Replace Fuse

Locate the fuse box, typically found 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 and inspect it for a break.
Replace with a new fuse of the same amperage rating.

3. Test and Replace Window Switch

If the fuse is intact, remove the door panel using a trim removal tool.
Disconnect the window switch connector and test for continuity with a multimeter.
If the switch is faulty, replace it with a new switch and reconnect.

4. Inspect and Replace Window Motor

If the switch is functioning, check the window motor by disconnecting it from the harness.
Test the motor directly with a power source; if it does not operate, replace the window motor.
To install, align it with the window regulator, secure it with bolts, and reconnect the wiring harness.

5. Reassemble Components

Reattach the door panel by aligning it with the clips and securing it with screws.
Reconnect the negative terminal of the battery.
