Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Fuse

Locate the power window fuse in the fuse box.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it with a new fuse of the same rating if blown.

3. Examine and Replace Power Window Switch

Remove the door panel carefully using a trim removal tool.
Disconnect the power window switch connector.
Test the switch with a multimeter; replace if faulty.

4. Test and Replace Window Motor

Use jumper wires to connect the window motor directly to the vehicle battery.
If the motor does not operate, disconnect and replace it with a new one.
Reinstall the motor and ensure it is properly secured to the window regulator.

5. Inspect and Repair Window Regulator

If the motor works, check the window regulator for any signs of damage or binding.
If damaged, remove the regulator and replace it with a new one.
Ensure proper alignment and secure all bolts to manufacturer specifications.
