Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, and a replacement fuse if necessary.
Ensure the vehicle is in park and the ignition is off.
Disconnect the battery to avoid electrical shock.

2. Check and Replace Fuse

Locate the fuse box under the dashboard or hood.
Identify the power window fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it if blown with the same amperage rating.

3. Inspect Power Window Switch

Remove the door panel using a flathead screwdriver to pry off clips.
Disconnect the power window switch harness.
Check for any visible damage; use a multimeter to test for continuity when the switch is pressed.
Replace the switch if faulty.

4. Test Window Motor

Reconnect the power window motor harness.
Use a multimeter to check for voltage when the switch is activated.
If voltage is present but the motor does not operate, remove the motor and connect it directly to the battery.
Replace the motor if it does not run with direct power.

5. Inspect Window Regulator

Remove the window motor from the regulator assembly.
Manually move the window up and down; listen for grinding noises.
Check for any obstructions or damage to the regulator; replace if necessary.
