Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and the ignition is turned off.
Gather necessary tools: multimeter, socket set, flat-head screwdriver, and a replacement fuse if needed.

2. Check and 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 or the owner’s manual.
Remove the fuse using a fuse puller or pliers and inspect for continuity with a multimeter.
If the fuse is blown, replace it with a new fuse of the same amperage rating.

3. Inspect Window Switch

Remove the door panel using a socket set and flat-head screwdriver to access the window switch.
Disconnect the switch connector and visually inspect for damage or corrosion.
Clean the contacts with electrical cleaner and reconnect the switch to test functionality.

4. Test Power Window Motor

If the switch is functional, apply direct battery voltage to the power window motor terminals using jumper wires.
If the motor operates, the issue may be with the wiring or switch; if it does not operate, replace the motor.

5. Check Wiring and Connections

Inspect the wiring harness leading to the window motor and switch for any signs of wear or damage.
Repair or replace any damaged wiring and ensure all connections are secure.
