Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to ensure safety while working on the electrical system.

2. Check and Replace the Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the power window fuse (refer to the owner’s manual for the exact fuse location).
Remove the fuse using a fuse puller or pliers, and inspect it for continuity.
- If blown, replace it with a new fuse of the same amperage (e.g., 30A).
- If not blown, proceed to the next step.

3. Test the Power Window Switch

Remove the power window switch from the door panel.
Use a multimeter to set it to continuity mode.
Test each terminal on the switch to ensure it functions correctly.
- If defective, replace the switch with a new one.

4. Inspect Wiring and Connectors

Carefully remove the door panel to access the wiring harness.
Inspect for any frayed wires or loose connections.
Repair or replace damaged wiring as necessary, ensuring all connectors are secure.

5. Test the Window Motor

With the door panel still removed, locate the window motor.
Connect a portable power source directly to the motor terminals.
- If the motor operates, the issue is likely with the switch or wiring.
- If it doesn’t operate, replace the window motor.
