Solution

1. Preparation

Tools Required: Screwdriver set, multimeter, fuse puller
Disconnect the battery to prevent electrical shock and short circuits.

2. Check and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Use the fuse puller to extract the power window fuse.
Visually inspect the fuse for a break in the filament. If broken, replace with a fuse of the same amperage rating.
Reconnect the battery and test the power windows.

3. Inspect Power Window Switch

Remove the door panel using a screwdriver and trim removal tool.
Disconnect the switch harness from the window switch.
Use a multimeter to check for continuity across the switch terminals while pressing the switch.
If no continuity is detected, replace the power window switch and reassemble the door panel.

4. Examine Wiring and Connections

Visually inspect the wiring harness connected to the window motor for any signs of wear or damage.
Ensure all connections are secure and free from corrosion.
Repair or replace damaged wiring as needed.

5. Test the Window Motor

Disconnect the window motor from the wiring harness.
Use a multimeter to check for voltage at the motor connector while operating the switch.
If voltage is present but the motor does not operate, replace the window motor. If no voltage is detected, further investigate the circuit.
