Remove the fuse using a fuse puller and inspect it for continuity.
- If blown: Replace with a fuse of the same amperage (usually 20A).

3. Test Power Window Switch

Reconnect the battery temporarily.
Use a multimeter to test the window switch for continuity:
- Disconnect the switch connector.
- Place the multimeter probes on the switch terminals and press the switch to check for continuity.
If defective: Replace the power window switch.
