Solution

1. Preparation

Gather tools: multimeter, socket set, flat-head screwdriver, Phillips screwdriver, and possibly a replacement fuse or switch.
Ensure the vehicle is in park and the ignition is off.
Disconnect the vehicle battery for safety.

2. Inspect and Replace the Fuse

Locate the fuse panel, usually found under the dashboard or in the engine compartment.
Identify the power window fuse using the diagram on the fuse panel cover.
Remove the fuse using a fuse puller or pliers.
Check for continuity using a multimeter; replace if blown with an equivalent fuse (typically a 30A fuse).

3. Test the Window Switch

Remove the door panel using a flat-head screwdriver and Phillips screwdriver.
Disconnect the window switch connector from the door panel.
Use a multimeter to check for voltage at the connector when the switch is pressed; it should show battery voltage (approximately 12V).
If no voltage is detected, consider replacing the switch.

4. Inspect Wiring Harness

Visually inspect the wiring harness in the door for any frayed wires or loose connections.
Tape or replace any damaged wires to ensure proper connectivity.

5. Test Window Motor

Disconnect the window motor from the door assembly.
Use a multimeter to test the motor for resistance; if it reads open (infinite resistance), the motor is faulty.
Apply direct battery power to the motor terminals to check if it operates; if it does not, replace the motor.
